external battery cabinets (see , “
5.2 Standard Battery Cabinet Installation or 5.1 Battery Cabinet Options ”).
2. Ensure that all power modules and battery modules are properly installed into the UPS cabinet.
3. If you are using power management software, connect your computer to either the DB9 or USB

4. When starting the UPS, apply input power to the UPS by closing the service circuit breaker:
• If external battery cabinets are installed, close the DC emergency disconnect switch button on the
back of each external battery cabinet. Insert the switch key supplied with the cabinet into the button
and turn clockwise 1/2-turn. Pull the button out to close the switch. Turn the key back counter-
clockwise, and remove the key.
5. The UPS control panel display automatically turns on whenever input power is present and at least one
power module is installed (see , “
6.1 UPS Startup ”).
6. Set up the initial operating parameters through the control panel display (see “
6.5 Initial Startup Parameters ” ).
7. If applicable, test proper operation of optional external control signals and computer communication before
connecting the load. (See “
8.5 DB-9 Communication Port ” for details.)
8. If there are receptacles on the UPS rear panel, plug the equipment to be protected into the UPS output
receptacles.
NOTE DO NOT protect laser printers with the UPS because of the exceptionally high power
requirements of the heating elements.
9. Turn on the equipment that is connected to the UPS.
10. If there is an external bypass switch, ensure a proper phase check has been completed then turn the
switch to UPS. Otherwise, close the load distribution circuit breaker(s).
