the connection to the power supply system.
6.2.4.1
Connecting a bridging bar to sizes 1 and 2
WARNING
Hazardous voltage!
Ensure there is no live voltage before mounting the bridging bars.
If you use the transfer switching equipment for switching between two sources (in
compliance with IEC 60947-6-1), a bridging bar must be used on the load side.
If you use the 3KC0 transfer switching equipment as a load transfer switch for switching
between two loads (in compliance with IEC 60947-3), you must mount a bridging bar on the
line side. You can mount the bridging bar on either the top or the bottom of the transfer
switching equipment.
The bridging bar is not included in the scope of supply. You can order the bridging bar as an
accessory. You will find further information on the bridging bar in chapter Bridging bars
(Page 58).
