the unit. It should be installed in a location free from:

• Corrosive gases or liquids

• Excessive vibration

• Airborne metallic particles

Mount the unit to a solid, non-flammable surface capable of bearing the weight using the

mounting bracket provided on the unit.

3.2 Proper Ventilation

In order to maintain air circulation for adequate cooling, minimum clearance around the unit

must be maintained. Allow six inches on each side and top, and 18 inches below.

Ensure air intake and exhaust openings are not obstructed. If the unit is mounted in a small

room, cabinet, or building, ensure there is adequate ventilation to provide sufficient cooling

for the unit.

3.3 Source Branch Circuit Protection

Branch circuit protection must be installed in the circuit sourcing the drive. See Table 2 for

recommended circuit breaker sizing, which is based on 125% of the rated input current.

Fuses may be used for circuit protection; consult local electrical code for proper sizing.

Installation of a disconnection means within sight of the drive is recommended.

3.8 Routing Power Cables

Note: Continuous metal conduit should be used for all power cables to reduce radiated

electromagnetic interference (EMI). The conduit must be securely connected to the drive

enclosure drive and the motor case for proper grounding. Consult local electrical code for

proper grounding methods.

Route power cables through the supplied openings in the bottom of the enclosure. Use

appropriate conduit or strain relief devices. Conduit hubs should be IMC or rigid steel

conduit and should be UL listed. Conduit hub locations are shown in Figure 5.

Important Note: Remove all metal shavings after cutting new openings.

Figure 5 – Essential Series Conduit Locations

3.9 Control Wiring

WARNING! When the drive is turned OFF using a control switch connected

to the AUX terminals, dangerous voltage may still be present on the input lines and

elsewhere inside the enclosure.

The output of the drive can be controlled with a switch connected between the AUX1 and

COM terminals and/or the AUX2 and COM terminals. When AUX1 to COM and AUX2 to

COM are closed, the drive enters run mode after a delay of approximately three seconds. If

AUX1 and AUX2 are closed when the unit is powered on, the output is energized after a

delay of approximately 16 seconds. When AUX1 or AUX2 to COM are open, the drive is

stopped.

To use a 0-5 VDC transducer or a 4-20 mA analog transducer, the optional analog I/O

board is required. Contact Phase Technologies if this upgrade is needed. Figure 6 shows

control terminal locations.
