I/T network and industrial operating modes
Overload, and Bypass
AC source in tolerance.
Overload, and Bypass

tolerance.
Output short circuit and
Bypass AC source in
tolerance.
Output short circuit and
Bypass AC source not
in tolerance.
Selection of protection devices

When sizing the upstream circuit breakers, the parameters presented below must be taken into account:
Line current values
power rating
5 kVA
7 kVA
11 kVA
Discrimination of upstream/downstream protections mentioned in paragraph 2.6 is achieved for a 30 m
cable length and 10 mm
Circuit breaker capacity must be selected according to the installation, length and cross section of cables.
Mode Industrial mode
Same as I/T network mode, but the UPS
does not return to normal mode if overload
released.
Load is transfered to Bypass AC source
with 10 milliseconds output break. The
UPS does not return to normal mode if
overload released.
Load is transfered to Bypass AC source,
the UPS returns to normal mode if the
short circuit is released by downstream
circuit breaker action (see section 2.6).
The load is transfered to Bypass AC source
with 10 milliseconds output break. The
UPS does not return to normal mode if the
short circuit is released by downstream
circuit breaker action (see section 2.6).

I/T network mode
Load is transfered to Bypass AC
source.
UPS returns to normal mode if
overload released.
The UPS shuts down and load is not
transfered to Bypass AC source.
The load remains powered by the
UPS.
The UPS shuts down after 3 minutes
if the short circuit remains.
The load remains powered by the
