3.4 Electrical installation
33.4.1 Commissioning
The commissioning of the UPS includes the
connection of the UPS and batteries, the
verification of the electrical installation and
operating environment of the UPS, the controlled
start-up and testing of the UPS, and customer
training.
WARNING!
DANGER!
3.4.2 Recommended cable sections and
fuse ratings
When selecting the cable cross-sections and the
protective devices, follow the recommendations
in the technical specifications document or follow
local standards.
DANGER!
Do not operate in case of presence
of water or moisture.
When opening or removing the UPS
covers you are exposed to
dangerous voltages.
To reduce the risk of fire, the unit
should only connect to a circuit
provided with branch circuit
overcurrent protection for:
• D curve 63 A rating (upstream
circuit), for 6kva models,
• D curve 80 A rating (upstream
circuit), for 10kva models

DANGER!
Risk of backfeed voltage. Isolate the
UPS by installing an external
isolating device between the mains
input and the UPS.
Before working on this circuit,
check for hazardous voltage.
ABB recommends that an external isolating
device is installed between the mains input
and UPS as shown in Figure 12 to protect
against backfeed currents.
