UNPAckING AND INSPEcTION - PAGE 3
Section 3: Unpacking and Inspection
The Comm/net Systems TPA 250 Series fuse panel was carefully packaged at the
factory to withstand the normal rigors of shipping. However, you should carefully
inspect the box and contents to confirm that no damage has occurred in transit. Most
shipping carriers require notification of shipping damage within twenty-four hours of
delivery, and it is the responsibility of the recipient to inspect the shipment immediately
upon receipt.
3.1 Package Contents
Included with your product are the following items:
y TPA 250 Series fuse panel
y Rear lacing bar assembly
y Clear plastic input safety covers
y Mounting hardware kit with necessary screws and washers
y Optional lacing bar kit or rear rack support kit (if ordered)
Section 4: Installation
4.1 Installation Preparation
When selecting an installation location, ensure that all of the following conditions are
met before proceeding.
4.1.1 Elevated Operating Ambient Temperature
If you install the panel in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient. Therefore,
take care to install the equipment in an environment compatible with the maximum
ambient temperature (TMA) specified in Section 5.
4.1.2 Reduced Air Flow
Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
4.1.3 Mechanical Loading
Mounting of the equipment in the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
4.1.4 Circuit Overloading
Give consideration to the connection of the equipment to the supply circuit and
the effect that overloading of the circuits might have on overcurrent protection and
supply wiring. Use appropriate consideration for equipment nameplate ratings when
addressing this concern.
4.1.5 Reliable Earthing
Maintain reliable earthing of rack-mounted equipment. Pay particular attention to
supply connections other than direct connections to the branch circuit (e.g., use of power
strips).
4.1.6 Disconnect Device
A readily accessible disconnect device must be incorporated in the building
installation wiring.

NOTICE
y THIS PRODUCT MUST BE INSTALLED WITHIN A RESTRICTED
ACCESS LOCATION WHERE ACCESS IS THROUGH THE USE
OF A TOOL, LOCK AND KEY, OR OTHER MEANS OF SECURITY,
AND IS CONTROLLED BY THE AUTHORITY RESPONSIBLE
FOR THE LOCATION. THIS PRODUCT MUST BE INSTALLED
AND MAINTAINED ONLY BY QUALIFIED TECHNICIANS.
y SUITABLE FOR MOUNTING ON CONCRETE OR
OTHER NONCOMBUSTIBLE SURFACE ONLY.
Step 1. Select either position 1, 2, or 3 to install the mounting ears (see Figure 3).
Step 2. Attach the mounting ears with included 10-32 hardware (see Figure 4).
Step 3. Select the equipment rack location for installation of the fuse panel then
secure the panel to the equipment rack by tightening hardware into the
mounting ears (see Figure 5).
4.2.1 Optional Cable Lacing Bar Kit (750-283-10)
Step 1. Attach the rear cable lacing bar assembly by tightening the (4) 10-32 socket
head screws into the threaded holes located on each side of the chassis
towards the rear (see Figure 5).
4.2.2 Optional Rear Rack Support Kit (750-277-10)
An optional telescoping rear rack support kit (750-277-10) is available to help secure
the panel to the rear of the equipment rack and to distribute panel weight evenly. In
addition to the standard lacing bar included with the TPA 250 fuse panel, a new lacing
bar is included with this kit which can be repositioned on any of the available lacing bar
holes depending on the depth of the equipment rack. Use a hex key to relocate the new
lacing bar if needed. See Pages 15 & 16 for mechanical dimensions of rear rack support
kit.
Step 1. Slide the rails of the rear rack support assembly into the lacing bar assembly
from section 4.2.1 (see Figure 6).
Step 2. Secure the mounting ears to equipment rack via the slotted holes or PEM nuts.

CAUTION
DO NOT ENERGIZE THE PANEL BEFORE
CHASSIS GROUND IS CONNECTED.
WARNING
DO NOT USE HARDWARE WITH A LENGTH EXCEEDING
3/4 INCH FOR CHASSIS GROUND CONNECTIONS.
The chassis ground is located on both sides of the panel. Two-hole lug landing
positions are provided. See table below for termination information. A minimum of #4
AWG chassis ground cable is required.

WARNING
FAILURE TO REINSTALL THE INPUT SAFETY COVERS
WILL CREATE AN ELECTRICAL HAZARD.
Included with each TPA 250 series fuse panel are (4) input safety covers which are
designed to help isolate the input terminations.
Step 1. Align the notch found on the included plastic safety covers with the slots
located at the rear of the panel.
Step 2. Firmly insert into place until fully seated (see Figure 10).
4.6 Output Connections
CAUTION
y DO NOT PERFORM THIS STEP ON
CIRCUITS WITH FUSES INSTALLED.
y ENSURE NO POWER IS PRESENT ON THE CIRCUIT
BEING WIRED BEFORE PROCEEDING.
NOTICE
SEE APPENDIX C ON PAGE 18 FOR TERMINAL SPECIFICATION
AND CABLE WHIP ORDERING INFORMATION.
There are (12) positive latching DC connector positions for the output circuits found
on the TPA 250 fuse panel, available in either 40A or 100A connector configurations.
Cable whips are available in a variety of lengths and wire gauges. Contact Comm/net
sales for cable whip ordering information. Refer to the front of the panel for the circuit
mapping card for circuit mapping information.
Step 1. Insert the DC plugs into the output receptacles until they click. The connectors
are keyed to ensure correct polarity (see Figure 11).

NOTICE
y USE BUSSMANN TPA TYPE FUSES ONLY.
y FUSES MUST CARRY A 10kA OR HIGHER INTERRUPT RATING.
Step 1. Ensure that connected loads are in the off position, then firmly insert a TPA
fuse of sufficient ampacity into the position to be fed (see Figure 12).
Step 2. Turn on the connected load.
4.8 Alarm Installation
NOTICE
WHEN DAISY CHAINING, THE ALARM MUST
BE MONITORED NORMALLY OPEN.
The TPA 250 series fuse panel has Form-C dry alarm contacts for remote alarm
monitoring. If alarm monitoring is required, (2) 8p8c (RJ-45) modular jacks are provided
for alarm connections. The (2) jacks support easy daisy chaining of panels.
The 8p8c modular jacks are located on the left side of the panel. Refer to mechanical
drawings found in Appendix A for more details.
Step 1. Plug in a UTP cable with a TIA/EIA T568B termination into the alarm jack (see
Figure 13). Refer to Table 4 for termination pinout information.
Step 2. Connect the cable to the site alarm monitoring system.
Step 3. If daisy chaining is required, connect a UTP cable with TIA/EIA T568B
termination into the second jack and connect the other end to the next panel
in the chain. Repeat this process until all panels are connected.
