External wiring
Run the connecting cables with intact external insulation jackets through the cable entries
into the connection chamber.
Make sure that the cable diameter and the clamping cross-section on the cable entry
are identical.
Tighten the hexagon nuts of the cable entry in such a way that the tightness of the
connection chamber and the strain relief protection at the connection point are
guaranteed. To determine the tightening torques, refer to the operating instructions
of the individual components.
Run the connecting wires in the connection chamber such that:
- the bending radii for the respective conductor cross-section do not fall below the
minimum permissible values.
- mechanical damage to the conductor insulation due to rubbing against sharp-edged
metal parts is avoided.
Terminals
Tighten the screws of the connection terminals in accordance with the specified
tightening torques.

Protective earth conductor

- The protective earth conductor must always be connected to the enclosure using
a cable lug (2). Place a washer (1) above and below the cable lug and secure the
screw (4) using a locking device (3).
- Regardless of the operating voltage, connect all bare, non-energised metal parts
to the protective system.
- The external protective earth conductor is designed to be fitted with a cable lug.
The cable must be run and fixed near to the enclosure to prevent movement of
the cable.
