Initial Start-Up and Electrical Checks

6.0 INITIAL START-UP AND ELECTRICAL CHECKS

1. Verify that the Input Output circuit breakers are off.

2. During initial system checks, disconnect all loads (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.

5. If you are using a distribution box that includes a Manual Bypass Switch, place the switch in

BYPASS position.

6. Turn on the branch circuit disconnect to apply voltage to the input terminal block.

7. Using a voltmeter, verify the expected L1-N voltage.

If no Manual Bypass Switch is used, there will be no output voltage at this time. If a Manual

Bypass Switch is used, verify that the same voltages appear at the Output terminals. If a Manual

Bypass Switch is used, the Bypass lamp will light by the switch. If no manual bypass switch is

used, there will be no output voltage at this time.

8. After verifying proper input voltage to the UPS terminal block, turn off the branch circuit power,

close all access panels to the distribution box, and reapply input power.

9. Close the Input circuit breaker located on the distribution box. The green AC INPUT lamp should

illuminate on the front panel.

10. Press the ON button for 1 second. The BYPASS lamp will light for several seconds before the UPS

ON 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 - Press the ON button for 1 second. The front BATTERY lamp will

light for about 15 seconds and then return to only the UPS ON and AC INPUT lamps being on.

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.
