7.Close the external battery cabinet circuit breaker.

8.Scroll through the measurements menu and verify that battery polarity and voltage are proper and within prescribed limits (see sections 7.3.2 and 7.3.5). For the

80 kVA model, the voltages will be about +260 and –260. For the 120 kVA model, the voltages will about +312 and –312 volts.

9.Close Parallel Isolator Switch (IA2) to position “I” (ON). UPS power is now present on the output terminal block and “LOAD PROTECTED” will appear on the LCD display. After 45-120 seconds, the battery LED will change from Flashing Green to Solid Green. This state change will take up to one minute.

On initial start-up follow steps 9-14. On re-start stop at 9.

10.Perform load transfer to Maintenance Bypass

Use Menu COMMANDS on UPS control panel and choose “LOAD TO BYPASS” (see sections 7.3.2 and 7.3.6) to transfer the load to the bypass source.

Close Maintenance Bypass Switch (IA1) to position “I” (ON). The LCD display will show “MANUAL BYP. CLOSED” and the LED indicators will appear as follows:
