If the cable bracket is located in the area of the cable sealing end, shift the cable bracket so that
the cable clamps are located underneath the sealing end.
Install the floor plates again and insert the rubber sleeves into the floor plates; fasten the floor
plates with bolts size M8.
Lead the earthing of the cable sealing end directly to the earthing busbar on the right side in the
connection compartment and bolt tight, keeping the maximum possible distance to live parts.
The cables and the cable sealing ends are mounted in the connection compartment.
10.10 Assembly of cable sealing ends for three-core cables
(except for contactor panel with panel width 435 mm)
Installing a deep bottom pan in the connection compartment is only required for panels with connection of
three-core cables in the connection compartment.
Damage to the switchgear panels
Observe the manufacturer’s information about the tightening torques of the
cable lugs / cable sealing ends.
The deep bottom pan can only be installed when the associated panel is standing
on its assigned place of installation.
For space-saving installation of the switchgear, the compact construction can hinder
the installation of deep bottom pans.
Dismantle deep bottom pan.
If possible, mount the parts of the deep bottom pan in the connection
compartment through the rear access to the connection compartment.
When a zero-sequence current transformer is installed, a fault current may arise
through the earth connection.
Lead the earthing cable back through the cable clamp and the zero-
sequence current transformer, and connect it to the earthing busbar.
Do not attach phase tapes to the cable sealing ends.
