When sizing the upstream circuit breakers, the parameters presented below must be taken into account:
Line current values
power rating
7 kVA
11 kVA
Discrimination of upstream/downstream protections mentioned in paragraph 2.6 is achieved for a 30 m
cable length and 10 mm² cross section.
Circuit breaker capacity must be selected according to the installation, length and cross section of cables.
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.
