Accessories for electrical connection

5.3.1.

Parking frame

Figure 19: Parking frame, example with SH plug/socket connector and cover

Application

Parking frame for safe storage of a disconnected plug or cover.

For protection against touching the bare contacts and against environmental
influences.

5.3.2.

External earth connection

Figure 20: Earth connection for multi-turn actuator

Application

External earth connection (U-bracket) for connection to equipotential compensation.

Terminal cross sections and earth connection tightening torques

Tightening torques

Terminal cross sections

Conductor type

3 – 4 Nm

2.5 mm² to 6 mm²

Solid wire and stranded

3 – 4 Nm

1.5 mm² to 4 mm²

Fine stranded

For fine stranded (flexible) wires, connection is made via cable lugs/ring terminals. When connecting
two individual wires with a U-bracket, cross sections have to be identical.
