3. If you are installing power management software, connect your
computer to the UPS communication port using the supplied
communication cable.
4. 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.
5. 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.)
6. Plug the equipment to be protected into the UPS output
receptacles. Turn on the equipment that is connected to the
UPS.
DO NOT protect laser printers with the UPS because of the
exceptionally high power requirements of the heating elements.
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.
