Eaton Power Xpert 9395 UPS Installation and Operation Manual 164201725—Rev 15 27
– Site specific specifications and requirements
– Local codes and regulations
• 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
3.2.4 UPS System Power Wiring Preparation:
• Select wire size according to the UPS nameplate.
• Do not use wire larger than the largest size listed in Table 5 through Table 9.
• Use terminal recommendations from Table 13 through Table 16.
• Size and number of conduits must not exceed those listed in Table 17.
• Select overcurrent protection input, battery, and output breakers according to the UPS nameplate rated for
either 80% or 100%.
• Follow all applicable NEC and local codes.
For three UPM external wiring requirements, including the minimum AWG size of external wiring, see:
• Table 5 for common battery system installations
• Table 6 for separate battery system installations
Table 9 for separate rectifier feed installations.
Wire sizes listed are for copper wiring only.
For UPM two external wiring requirements, including the minimum AWG size of external wiring, see:
• Table 7 for common battery system installations
• Table 8 for separate battery system installations
• Table 9 for separate rectifier feed installations.
Because of the future upgradability to a fully rated 825 kVA UPS with the addition of the FI-UPM, the UPS
wiring is specified for 825 kVA in Table 7 and Table 8.
Wire sizes listed are for copper wiring only.
