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.
