The ISBM and UPM sections are shipped with debris shields covering the ventilation grills on top of the
sections. Do not remove the debris shields until installation is complete. However, remove the shields
before operating the UPS. Once the debris shields are removed, do not place objects on the ventilation
grills.
•
In a common battery system, single and multiple UPMs are powered from one common battery source. In
a separate battery system, multiple UPMs are each powered from separate battery sources.
•
UPSs in distributed bypass and parallel systems must use a separate battery system.
•
On a UPS configured for separate rectifier inputs, all sources that feed the separate rectifier inputs must
be derived from a common ground point.
•
A Field Installed UPM (FI-UPM) is always designated as UPM 4.
•
The Power Xpert 9395-825/550 two UPM UPS is upgradable to a fully rated 825 kVA with the addition of
the FI-UPM. Because of this future upgradability, the UPS wire and external overcurrent protection ratings
listed in the following tables are specified for 825 kVA.
If the power rating listed on the nameplate of the installed UPS is not found in the following tables, wire the
UPS using the fully rated specifications. Otherwise, calculate the required wire, conduit, and breaker sizes
using the following guidelines in addition to those already listed in paragraph
