The conductor cross sections apply for maximum currents:
(1) For PVC-insulated copper cables (at 70℃ )
(2) When routed in conduits for electrical installations
(3) When air temperature surrounding the conduits does not exceed 30℃
(4) For cable lengths up to 30 m
Connect the Protective Earthing (PE) cable first.
Connect other cables as shown in the connection terminal representations on the preceding
and following pages.
Ensure that the UPS is isolated before removing front terminal protective panel.
5.3 Suggested cable and protective devices
Caution!
All cables should always use copper cable type.
In order to gain access to the external electrical connections it is necessary to remove the
front terminal protective panel of the UPS. Before the cables are connected they shall be
passed through the cable glands to hold them in position and tightened.
Notice!
Should there be any variation in the conditions it will be necessary to verify whether
the cable dimensions satisfy the requirements of IEC-287 and DIN VDE 0298. In cases
where the cables are so long that they cause a drop in voltage of >3%, a larger dimen-
sion shall be selected.
