15. Reinstall all UPS cover panels.
16. If the UPS will not be operated immediately, switch the bypass

switch to SERVICE and push the DC disconnect switch on the

back panel of the external battery cabinet closest to the UPS.
When starting the UPS, apply input power to the UPS by

closing the service circuit breaker or turning the bypass switch

to the LINE position. If an external battery cabinet is

connected, unlock and pull out the DC disconnect switch on its

back panel.

17. The UPS front panel display automatically turns on whenever

input power is present and at least one power module is

installed. Set up the initial operating parameters through the

front panel display (see

Initial Startup Parameters" on

page 56).

NOTE The unit has no physical On/Off switch. The UPS On/Off function must be

accessed through the front panel display.
NOTE If the UPS has been manually set to operate in Bypass or Battery mode, change

the System mode menu selection (menu 2) to Auto to return to normal Auto mode

operation.

18. Test proper operation of optional external control signals and

computer communication before connecting the load. (See

DB-9 Port Pin Functions" on page 71 for details.)

19. If there are receptacles on the UPS rear panel, plug the

equipment to be protected into the UPS output receptacles.
DO NOT protect laser printers with the UPS because of the

exceptionally high power requirements of the heating elements.

20. Turn on the equipment that is connected to the UPS.
21. If there is an external bypass switch, turn it to UPS. Otherwise,

close the load distribution circuit breaker(s).

NOTE The total volt-ampere load must not exceed the volt-ampere rating of the entire

cabinet. See Balancing Receptacle Loads" on page 58 for additional information.
