UPS Startup

W A R N I N G

Only qualified service personnel (such as a licensed electrician) should perform the

UPS installation and initial startup. Risk of electrical shock.

Verify that UPS installation has been carried out correctly and the UPS ground has been connected. Figure 6 on page 23 and Figure 14 on page 39 show the location of the switches and breakers.

NOTE Bypass startup is recommended whenever the load is connected to the UPS.

Bypass Startup

You can start up the UPS in Bypass, allowing utility to power the load. To start up the UPS with the Maintenance Bypass switch in the BYPASS position:

1.Remove the front panel. Lift from the bottom of the panel and then pull out (see Figure 5 on page 22).

2.Verify that the Maintenance Bypass switch is in the BYPASS position.

3.Switch on utility power where the UPS is connected. The load is now powered by the utility.

4.Turn the UPS battery circuit breaker CB1 and optional CB2 to the ON position.

5.Turn the Maintenance Bypass switch to the SERVICE position.

6.Start the UPS by turning on the UPS ON/OFF switch (the position).

The UPS checks its internal functions, synchronizes to utility, performs input voltage and frequency checks, and supplies power to the output. The UPS starts in approximately three to five minutes. The UPS ON, LINE ON, BYPASSED, and LOAD indicators illuminate.
