NOTE All power modules in the Eaton 9170+ UPS cabinet must be of the same type:
Split-phase power modules have brown labels; universal (single-phase) power modules have
black labels. Do not mix brown and black modules in the same UPS cabinet.
NOTE Do NOT install more than seven power and/or optional battery charger modules in
the system.
3. Insert the power modules into the upper slots of the cabinet. To
insert a power module:
Lower the front slightly and lift the rear edge over the safety stop
on the center support rail. Keep the module handle extended until
the module is fully inserted (see Figure 48).
Raise the power module handle to secure the module into the
cabinet. Be sure the handle latch snaps into place. Tighten the
thumbscrew on the handle.
