Attention
Before any work is started, ensure that the cables are free of tension and
no power can be switched on.
To prevent a deformation of the bus-bar and to keep the foot of the
terminal free of torsion, it is recommended to hold the cable when
removing the terminal screw. The grounding Protection prevents
inappropriately high contact tension with reachable metal pieces. The
grounding of the Protect D is realized via the grounding screw
(
/ PE). Before UPS start ensure that the Protect D is grounded
according the regulations, e.g. VDE 0100.
Before starting the connection, check that:
• the values of the mains voltage (input voltage) and frequency complies
with the values on the label on the UPS,
• the grounding connection complies with the IEC norms or with the
regional regulations,
• the UPS is connected to the mains via a separate and fused line in a pre-
switched NS distribution,
• the power fuse in the LV distribution has the same or higher value as
indicated on the label on the rear of the UPS appliance.
