Third Party Battery Breaker Requirements
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
All selected battery breakers must be equipped with instantaneous trip
functionality with an undervoltage release coil or a shunt trip release coil.
Failure to follow these instructions will result in death or serious injury.
NOTE: There are more factors to consider when selecting a battery breaker
than the requirements listed below. Please contact Schneider Electric for more
information.
Design Requirements for Battery Breaker
Battery breaker rated DC voltage > Normal battery
voltage
The normal voltage of the battery configuration is
defined as the highest nominal occurring battery
voltage. This can be equivalent to the float voltage
which may be defined as number of battery blocks x
number of cells x cell float voltage. Ex: 32 blocks of 6
cells of 2.27 = 435 VDC.
Battery breaker rated DC current > Rated discharge
battery current
This current is controlled by the UPS and must include
maximum discharge current. This will typically be the
current at the end of discharge (minimum operation
DC voltage or in overload condition or a combination).
DC landings Three DC landings for DC-cables are required.
AUX switches for monitoring One AUX switch must be installed in each battery
breaker and connected to the UPS. The UPS can
monitor one battery breaker.
14 990-5992C-001
Specifications For External Batteries
Design Requirements for Battery Breaker (Continued)
Short-circuit breaking capability The short-circuit breaking capability must be higher
than the short-circuit DC current of the (largest)
battery configuration.
Minimum trip current The minimum short-circuit current to trip the battery
breaker must match the (smallest) battery
configuration, to make the breaker trip in case of a
short circuit, up to the end of its life time.
Guidance for Organizing Battery Cables
NOTE: For 3rd party batteries, use only high rate batteries for UPS
applications.
NOTE: When the battery bank is placed remotely, the organizing of the cables
is important to reduce voltage drop and inductance. The distance between the
battery bank and the UPS must not exceed 200 m (656 ft). Contact Schneider
Electric for installations with a longer distance.
NOTE: To minimize the risk of electromagnetic radiation, it is highly
recommended to follow the below guidance and to use grounded metallic tray
supports.

For External Batteries Backfeed Protection
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
contactor can be used for this purpose. In the shown examples, the isolation
device is a 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 Specifications, page 11.
NOTE: The 24 V source should be generated from the switchgear input
source in single mains configurations and from both the switchgear input and
bypass source in dual mains configurations.
