S
If the load requires a neutral, a bypass source neutral must be provided. If the load
does not require a neutral and there is no neutral conductor connected at the
bypass input, a neutral to ground bonding jumper must be installed. DO NOT install
both a source neutral and a bonding jumper. See Table 3‐4, Table 3‐5, Table 3‐6 or
Table 3‐7 for neutral bonding jumper wire sizes. The bonding jumper must be
copper wire.
C A U T I O N
HIGH IMPEDANCE GROUND SOURCES - If the supply source is a high impedance ground (IT) type, the
neutral‐forming transformer kit must be used instead of pulling a neutral from the source. In no
circumstances shall a neutral to ground bonding jumper be installed in the UPS.
C A U T I O N
DELTA SOURCES (TN‐S) - The UPS cannot be operated from a mid‐point or end‐point grounded delta supply
source. With this type of supply source, there is no capability to provide an output neutral. In no
circumstances shall a neutral to ground bonding jumper be installed in the UPS.
S
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.
S
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.
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
On a UPS configured as an Input Output Module (IOM), requirements for bypass
input wiring, termination, conduit, and bypass breaker are not applicable.
S
A Field Installed UPM (FI-UPM) is always designated as UPM 4.
S
The Eaton 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.
