and Battery Cabinets
Note: If you use flexible conduit to connect the UPS and
battery cabinets, you may be able to achieve the service
clearances by moving the UPS. If this is the case, you
must still leave 12 inches (305 mm) clearance at the front
and back of the UPS for ventilation. Do not block the ventilation
holes on each side of the front panel.
103 Location Requirements
• Install the FERRUPS as close as possible to the equipment it will protect. If this distance is more than 25 feet
(7.6 meters), transient noise can reappear in the electrical distribution system.
• If the FERRUPS batteries are in a separate cabinet, the battery cabinet should be as close to the FERRUPS as
possible. If the batteries will be farther away from the unit than the standard cables allow, call the nearest Best
Power office for assistance.
104 Receiving and Moving the FERRUPS and the Batteries
Note the FERRUPS and battery cabinet weights in the User Manual. Before you unload or move the FERRUPS
or the battery cabinet, make sure your method of moving them is appropriate for their weights.
105 Storage and Operating Environment
Storage Temperature: Store a FERRUPS with internal batteries or a battery cabinet at –20° to +40°
Celsius (–4° to +104° F). Batteries will have a longer shelf life if you store them
below 25° C (77° F). A UPS without internal batteries may be stored at –20° to
+60° Celsius (–4° to +140° F).
Operating Temperature: 0° to 40° Celsius (32° to 104° F), up to 95% relative humidity without
condensation. The batteries last longer if the operating temperature stays below 25°
C (77° F).
Ventilation: The air around the UPS must be clean, dust-free, and free of corrosive chemicals or
other contaminants. The air must be free to circulate around the UPS cabinet and
any battery cabinets. Do not place the UPS or batteries in a sealed room or
container.
High Altitude Operation: The maximum operating temperature drops 1° Celsius per 300 meters above sea
level (2° F per 1000 feet above sea level). Maximum elevation is 3000 meters
(10,000 feet).

106 Bypass Switches
If your FERRUPS model does not have a power cord and plug, you should have a Best Power bypass switch.
The cabinet for these switches may be separate (external) or attached to the back of the UPS (internal).
The bypass switch has four positions (see Table 5 below). In the UPS or LINE positions, AC input power is
still connected to the input terminals inside the UPS once it is installed. To disconnect AC input power
during maintenance or service, turn the bypass switch to SERVICE. For Make-Before-Break switches, please
note that you must press the red button before you can change the switch position.
Table 5: Bypass Switch Positions
Bypass switches may be Make-Before-Break (MBB) or Break-Before-Make (BBM).
Make-Before-Break switches make a new connection before they break the present connection. For example, if
you turned the switch from “UPS” to “LINE,” the bypass switch would connect your protected equipment to AC
input power before disconnecting the equipment from UPS output power. Make-Before-Break switches are not
for use with 208 VAC.
Break-Before-Make switches break the present connection before they make a new one. If you turned a Break-
Before-Make switch from “UPS”to “LINE,” the switch would disconnect your protected equipment from UPS
output power before connecting the equipment to AC input power.
Bypass switches come in four models, and each model has its own ratings for current and voltage. Table 6 below
lists the ratings and weights for Best Power bypass switches.
Table 6: Bypass Switch Ratings and Weights
Switch Position Explanation
LINE Connects the loads (protected equipment) directly to AC line input and disconnects UPS output. AC
line input is still connected to the UPS itself.
OFF Disconnects the protected equipment from both UPS output power and AC input power.
SERVICE
UPS
Like the LINE position, SERVICE connects the loads (protected equipment) directly to AC line input
and disconnects UPS output. However, since SERVICE also disconnects AC input, this is the
appropriate switch position during UPS maintenance or repair.
Connects the UPS output to the protected equipment.

200 Overview of UPS Installation
Figure 6 below shows a typical installation for FERRUPS units that do not have an input power cord and plug.
This diagram shows a unit with a separate battery cabinet and a separate bypass switch. In units with internal
bypass switches, the switch is attached to the back of the UPS, and the UPS is already wired to the switch.

300 AC Installation of the UPS and Bypass Switch
(for Qualified Personnel Only)
301 Starting ACInstallation
1.Find the FERRUPSID label on the back panel, and note the following:
Model Number:__________ Input Voltage:__________ Output Voltage:__________
2.Next, find the bypass switchs ID label, and write down the following:
Model Number:__________ Make-Before-Break (MBB) or Break-Before-Make (BBM)? __________
External (Separate) or Internal (Attached)? __________
3. Now, answer the questions below. Remember that the FERRUPS provides single-phase power only.
a. Does the input voltage at the AC service panel match the input voltage on the UPS ID label?
Service panel voltage: ________ = UPS Input Voltage: ________ lYes lNo
b. Does the output voltage on the UPS ID label match the voltage your loads (protected equipment) will
need?
Load voltage: ________ = UPS Output Voltage: ________ lYes lNo
If the answer to either a. or b. is No, call the nearest Best Power office for assistance.
CAUTION
Read the cautions below before you begin AC installation:
A.All UPS units contain hazardous AC and DC voltages. Because of this, a qualified electrician must install
the UPS and AC line service. The electrician must install AC line according to local and national codes.
B.This equipment relies on protection devices in the building installation. These devices must be installed
within sight of the UPS.
C.Before you install, maintain, or service the UPS, always remove or shut off all sources of AC and DC
power and shut off the UPS. You must disconnect AC line input at the service panel, turn the DC switch
OFF and shut the UPS down to make sure it will not supply output voltage.
D.Whenever AC and/or DC voltage is applied, there may be AC voltage at the UPS terminals; this is true
because the UPS can supply power from AC input or from its batteries. To avoid equipment damage or
personal injury, always assume that there may be voltage at the UPS terminals.
E.Before you install the bypass switch, make sure that the bypass switch is OFF.
F.To reduce the risk of fire or electric shock, install the FERRUPS and the batteries in a temperature-
controlled and humidity-controlled indoor area free of conductive contaminants. See Section 105 for
operating environment specifications.

302 Installing Models with External Bypass Switches
1. Mount the bypass switch within sight of the UPS. If you do not have a Best Power bypass switch, or if the
fuse box or panel is out of sight, you must install a separate disconnect switch next to the UPS.
2. Remove the six screws in the bypass switch front panel and remove the panel. Remove the foam packing
material that is inside the bypass switch. Then, remove knockouts in the bottom of the bypass switch for AC
Line Input, AC to UPS Input, AC from UPS Output, and AC to the UPS-protected equipment (loads).
3. Next, remove the top portion of the UPS cover.
To remove the top UPS cover, first pull the top front panel out slightly until it clicks once; the holes in the
right side of the panel can help you do this. Do not strain the ribbon cable behind this panel. If you need
to remove the panel completely, you can disconnect the ribbon cable, but the display will not operate until
you reconnect it. Remove the three screws on each side of the UPS and one screw on the top of the UPS
(toward the back). Then, lift the cover off the UPS. See Figure 7.
4. Remove the knockouts in the FERRUPS back panel for AC Input and AC Output.
5. Install the conduit adapters. AC Input and AC Output conductors must be run through separate conduit. UPS
output circuits shall be installed in dedicated conduit systems and not shared with other electrical circuits.
CAUTION
To prevent electrical shock or damage to your equipment, make sure the FERRUPS is OFF before you
remove the cover. The circuit breaker or disconnect switch must also be off at the AC input service panel.
Remove these
screws. Pull this panel forward until it
clicks once. DO NOT STRAIN
THE RIBBON CABLE BEHIND
THIS PANEL. If you need to
remove the panel,
disconnect the ribbon cable first.
The display will not operate with
the cable disconnected.
These panels are not
attached when you receive
the UPS. To attach them,
see the Startup section of
the
User Manual
.
Remove three
screws on this
side.
CAUTION
To prevent electrical shock or damage to your equipment, make sure the AC input is OFF at the service
panel and the bypass and AC Disconnect switches are OFF before you connect any wires to the bypass
switch terminal strip.

6.Find the terminal strip inside the bypass switch. Using the label on the back of the bypass switchs access
panel and the Installation Wiring Diagram for your UPS, make the terminal strip connections and tighten all
connections securely. Use copper wire that is the appropriate size for the current draw. See Figure 8 for a
sample label.
Figure 8
7.Find the proper output neutral-to-ground connection in Figure 13 on pages 18-19. At the UPS terminal strip,
connect the neutral-to-ground (neutral-to-earth) wire to the proper output terminal before making any other
connections to the UPS. The neutral-to-ground wire is a green and yellow wire labeled WIA-0424. One end
of this wire is already connected to ground (earth) on the UPS terminal strip.
8.Notice that there is a cable routed out of the left side of the bypass switch cabinet. The wires in this cable
must be connected to the UPS logic board to provide bypass status signals to the UPS. To connect the wires,
follow the steps below. If you plan to use the Emergency Power Off feature, see Appendix A.
a) Route the wires through the UPS grommet shown below and to connector J13 on the logic board.
b) Pull the 8-pin connector at J13 apart as shown. The portion you remove from the connector has 8 possible
connection points.

c) Loosen the standard screws on the J13 connector as shown in Figure 9.
d) If your bypass switch is Make-Before-Break (MBB), connect the red and black pair of wires to the
terminals marked 3 and 4 in Figure 9, with the red wire going to 3 and the black wire going to 4.
e) For all external bypass switches, connect the white and black pair of wires to 5 and 6, with the white wire
going to 5 and the black wire going to 6.
Note:If you need to make a connection for an Emergency Power Off signal, complete the steps in
Appendix Abefore you go on.
f) Tighten the screws to secure the connections (torque specification is 2.61 inch-pounds/0.3 N-m), and
reattach the connector to J13 on the logic board.
g) Use the tie-wraps provided to secure the cable. See Figure 9.
9.Using the Installation Wiring Diagram (Figure 10, 11,or 12) for your UPS, make the UPS terminal strip
connections and complete the ACinstallation wiring. Read the notes with each diagram carefully. See
Figure 13for UPS terminations.
Make all connections exactly as shown on the Installation Wiring Diagram to make sure the phasing is
correct. Good ground connections are necessary to reduce electrical noise and make UPS and load operation
safe. Follow the grounding guidelines on the installation wiring diagram.
Torque for these connections should be 10.6-12.3 inch-pounds (1.2-1.4 Newton-meters).
10.If your UPS has one or more separate battery cabinets, go on to Section 400to install them. If not, go to
Section 500to set UPS parameters and perform the phase check.

NOTE 2:The UPS bypass switch must be installed within sight of
the UPS. To properly install, complete the voltage and phase
check procedure in Section 500. The wires coming from the
side of the switch must be connected as described in step 8
on pages 13-14.
NOTE 3:The customer must provide and install this ground
(earth) connection per NEC Sections 250-5(d), 250-26, 250-91
and 250-92, or local code requirements. This grounding electrode
conductor must be at least #8 AWG (8.36 mm2) per NECtable
250-94. If the UPS input circuit conductors are larger than #8
AWG (8.36 mm2), Best Power requires the grounding electrode
conductor to be the same size (ampacity) as the largest UPS
input circuit conductor. See NEC Section 110-3(b). Conduit is not
considered an acceptable grounding electrode conductor. Best

conductor through metallic conduit. This conductor may require
protection from physical damage according to local code
requirements.
NOTE 4:All AC circuit conductors, including the neutral and
equipment grounding conductors, must be the same size
(ampacity), have the same rating (75° C copper wire), and be
sized according to the input circuit breaker. The UPS input and
output conductors must be run through separate conduits.
NOTE 5:The customer must provide output overcurrent
protection. See NECSection 240-21 or local requirements. See
Table 12 on page 11 for maximum output overcurrent protection
device ratings.
