S The UPS cabinet is shipped with a debris shield covering the ventilation grill on top
of the unit. Do not remove the debris shield until installation is complete. However,
remove the shield before operating the UPS. Once the debris shield is removed, do
not place objects on the ventilation grill.

common battery source. In a separate battery system, multiple UPMs are each
powered from separate battery sources.
S UPMs in distributed bypass and parallel systems must use a separate battery
system.
S On a UPS configured for separate rectifier inputs, all sources that feed the separate
rectifier inputs must be derived from a common ground point.
S A Field Installed UPM (FI-UPM) is always designated as UPM 4.
