3.5-6 kVA Start-up Checklist

1.Remove POD from box. Set aside the two UPS battery fuses inside the user manual packet for later installation.

Steps 2 – 4 apply to UPS Hardwire Input / Output connections ONLY.

For standard plug connections, skip to step 5.

2.Note conduit knockouts on unit side. Remove the four screws securing the terminal block access cover.

3.Wire UPS input and/or output per NEC (NFPA 70) and all applicable local codes. Use 75 degrees C copper wire. See Site Planning Data and Table NEC Wire Specifications in the Appendix. Note that terminations used for an L-L-N-G system differ from those used for an L-N-G system as indicated by the terminal block labels below.

4.Reassemble the POD.

5.With UPS OFF, remove hex nuts on the two guide pins on the rear of the UPS.

6.While holding the unit with the Maintenance Bypass Switch on the top, guide the unit so that the UPS guidepins insert in the holes at the top and bottom. As the guidepins insert, ensure that the two sets of connectors align. Once all the connector pins make contact, push the unit onto the UPS until it is in contact with the back of the UPS.

CAUTION: If connector pins do not align, DO NOT force the unit onto the UPS. It may break the pins. Instead, try to reinstall the unit.

7.Look at the connection from the side. There should be no gap between the unit connectors and the UPS connectors. If there is, push the unit further until no

gap exists. Thread hex nuts back onto guide pins with a 7/1 6” wrench.

8.Verify the Maintenance Bypass Switch (switch SW2 on the unit) is in the ”UPS” position

9.Turn off all UPS-supported loads and plug them into the POD.

10.Install the two battery fuses (F3 and F4). The second fuse completes a circuit. The spark is a normal indication.

11.Roll unit to final position. Allow at least one foot of rear clearance. Adjust leveling feet.

12.Plug unit power cord into the wall outlet.

13.Turn ON customer-supplied wall outlet circuit breaker to supply power to UPS control circuits. The fan and the LCD display activate.

14.The LCD display prompts you to review and accept default settings (see page 11) or configure the UPS for your application.

15.After configuration, automatic self-tests begin. If self- tests are OK, the Close Breaker then Press ON message appears and an alarm sounds. Press Alarm Silence Button to silence the alarm. If any other message appears, contact Liebert at 1-800-222-5877.

16.Turn ON Output Circuit Breaker on back of UPS by turning it OFF, then ON again to reset it. Press the front panel ON button. The UPS tests the inverter and displays the Normal Operation message.

17.Green light on unit indicates power available for loads and normal UPS operation.

18.Turn on each critical load one at a time. The UPS provides filtered, regulated power to protect valuable processes and data.
