This UPS contains its own energy source (batteries). The output receptacles may carry hazardous voltage
even when the UPS is not connected to an AC supply. When AC input voltage is present, the Eaton 9PXM
system can provide output voltage even though its batteries are disconnected. To confirm that there is no
UPS output voltage, always disconnect all of the AC input sources and unplug all two battery modules per
slot of internal batteries; if the UPS has one or more separate battery cabinets (EBMs), open (push in) the
DC emergency disconnect switch button on each battery cabinet or unplug two battery modules in each
slot of the battery cabinet.
•
To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity controlled, indoor
environment, free of conductive contaminants. Ambient temperature must not exceed 40°C (104°F). Do
not operate near water or excessive humidity (95% maximum).
•
For optimum battery life, ambient temperature should not exceed 25°C (77°F). Battery life is substantially
reduced if ambient temperature is higher.
•
Do NOT attempt to move the cabinet with the power or battery modules installed.
The UPS power modules (UPMs) are installed in the left hand slots of the UPS facing the user. Battery modules
are installed in the left or right hand slots (it takes two battery modules per slot to equal one battery string).
Removal of the power modules and battery modules is the reverse of these procedures.
Install the UPMs into the Eaton 9PXM cabinet: as follows:
1.
Remove the front cover(s) of the cabinet. The covers have magnetic latches on the left and right sides that
hold them in place.
2.
Insert the power modules into the left hand slots of the cabinet. Push each module firmly until it contacts
the connections in the rear of the slot.
3.
Tighten the captive screw
4.
To install the battery modules

•
NOTE 1
Place battery modules beside all power modules in the UPS cabinet. Two battery
modules installed on top of each other are required for each battery slot and can be
removed separately.
NOTE 2
If you are installing a super charger module in the UPS, the super charger can be
installed in any of the left side slots. In the EBM, the super charger can only be installed
in the lower left side slot.
NOTE 3
The installation procedures of the optional battery cabinet (EBM) battery, and super
charger modules are identical to the UPS units.
NOTE 4
Battery modules are shipped fully charged. It is recommended to charge the batteries
for 48 hrs. after installation to ensure full power. If AC power fails before full battery
charge, backup will be available but for a reduced duration.
Slide the lower battery module fully into the slot until it contacts the connections in the rear of the slot.
Repeat the procedure with the upper battery module.
Install the retaining bracket and tighten the captive screw with a Phillips screwdriver.
