NOTE: Schneider Electric recommends to connect the optional temperature
sensor kit E3SOPT003 (R25=5 kohm, B25/50=3275) to J2 to monitor the
battery temperature.
NOTICE
RISK OF EQUIPMENT DAMAGE
•
Connect the Schneider Electric shunt trip coil LV429390 to the
recommended battery breaker to protect the battery.
•
The battery breaker contact drive (J6–1) can provide a maximum of +24 V,
200 mA to the shunt trip coil. If this value is exceeded it can damage the
UPS.
Failure to follow these instructions can result in equipment damage.
Input connections are considered Class 2/SELV.

Backfeed Protection
10–30 kVA 3:1
Backfeed Protection
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
In systems where backfeed protection is not part of the standard design, an
automatic isolation device (backfeed protection option or other device meeting
the requirements of IEC/EN 62040–1) must be installed to prevent hazardous
voltage or energy at the input terminals of the isolation device. The device must
open within 15 seconds after the upstream power supply fails and must be rated
according to the specifications.
Failure to follow these instructions will result in death or serious injury.
When the UPS input is connected through external isolators that, when opened,
isolate the neutral or when the automatic backfeed isolation is provided external to
the equipment or is connected to an IT power distribution system, a label must be
fitted at the UPS input terminals, and on all primary power isolators installed
remote from the UPS area and on external access points between such isolators
and the UPS, by the user, displaying the following text (or equivalent in a language
which is acceptable in the country in which the UPS system is installed):
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Risk of Voltage Backfeed. Before working on this circuit: Isolate the UPS and
check for hazardous voltage between all terminals including the protective
earth.
Failure to follow these instructions will result in death or serious injury.
An additional external isolation device must be installed in the UPS system. A
magnetic contactor or a circuit breaker with UVR (Under Voltage Release)
functionality can be used for this purpose. In the shown examples, the isolation
device is a magnetic contactor (marked with a MC1 for single mains systems and
marked with a MC1 and MC2 for dual mains systems).
The isolation device must be able to withstand the electrical characteristics as
described in Input Specifications, page 11.
NOTE: The 24 V source should be generated from the input source in single
mains configurations and from the both the input and bypass source in dual
mains configurations.
