UPSs for Internal Batteries

22 990-6204C-001
Overview For Internal Batteries

The impedance of the bypass paths need to be controlled in a parallel UPS

system. When operating in bypass mode, the parallel load sharing is determined
by the total impedance of the bypass path comprising cables, switchgear, static
bypass switch, and cable formation.

NOTICE
RISK OF EQUIPMENT DAMAGE
To ensure correct load sharing in bypass operation in a parallel system, the
following recommendations apply:
• The bypass cables must be the same length for all UPSs.
• The output cables must be the same length for all UPSs.
• The input cables must be the same length for all UPSs in a single mains
system.
• Cable formation recommendations must be followed.
• The reactance of busbar layout in the bypass/input and output switchgear
must be the same for all UPSs.
If the above recommendations are not followed the result can be uneven load
sharing in bypass and overload of individual UPSs.
Failure to follow these instructions can result in equipment damage.

Backfeed Protection For Internal Batteries

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 16.
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.
NOTE: The backfeed box in the diagrams is a customized device – please
contact Schneider Electric for details.
