Initial Startup and Electrical Checks

7.1L14-30P Plug-in Connections—Including the PD-001 Distribution Box

! WARNING

Miswiring power to the input (L1-L2-N-G) or connecting to single phase voltages (L-N-G only) may damage the UPS. A qualified electrician should verify that the L14-30R is properly wired before attaching the UPS.

If the configuration program has been used to set the L-N voltage at 100, 110 or 115, then the input phase angle is required to be 180 degrees.

If the configuration program as been used to set the L-N voltage at 127 VAC, then the input phase angle is required to be 120 degrees (leading or lagging).

1.Verify that the input and output circuit breakers are off.

2.During initial system checks, unplug all loads (or open load disconnects).

3.Inspect all wiring, cables and connection.

4.If external battery cabinets are used, verify that the battery interconnect cables are fully inserted in the sockets. Turn on the battery cabinet circuit breaker.

5.If you are using a distribution box that includes a manual bypass switch, place the switch in BYPASS position.

6.Plug in the UPS input plug.

7.Turn on the branch circuit disconnect to apply voltage to the UPS input.

8.If no manual bypass switch is used, there will be no output voltage at this time. If a manual bypass switch is used, the Bypass lamp will light by the switch

9.Close the input circuit breaker located on the distribution box. The green Line lamp should illuminate on the front panel.

10.Press the Start button for 1 second. The Bypass lamp will light for several seconds before the Inverter lamp turn on continuously. If the batteries are determined to charged above 80%, an automatic battery test will run for about 15 seconds.

11.Close the output circuit breaker on the rear of the UPS. If a manual bypass switch is used, the Inverter lamp by the switch will light. If a manual bypass switch is used, transfer the switch to the Inverter position. The output terminal block will be powered at this time.

12.Perform a Manual Battery Test by pressing the ON button for 1 second. The front Battery lamp will light for about 15 seconds and then extinguish, leaving only the Inverter and Line lamps illuminated.

13.Review all setting option provided by the configuration program. Some changes require that the UPS be OFF. If this is the case, these should be programmed before powering the loads. The configuration program is described in the next section.

14.Connect all loads for normal operation.
