NOTICE
Damage to the switchgear panels
Observe the manufacturer's information about the tightening torques of the
cable lugs / cable sealing ends.
INFORMATION
The connection points of the cable sealing ends (1) and the floor openings in the
floor cover (6) are not lying perpendicularly one above the other.
Mount the cables and the cable sealing ends with a slight inclination
towards the rear side; please refer to the side view shown below.
INFORMATION
The deep bottom pan can only be installed when the associated panel is standing
on its assigned place of installation.
INFORMATION
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.
INFORMATION
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.
INFORMATION
Do not attach phase tapes to the cable sealing ends.
