• 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.

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).
