Danger!
Explosion hazard from connection damage
Manipulating connections outside of the specified ambient temperature range can lead to
material damage, resulting in an unwanted failure of the connection. This could result in an
increased explosion hazard in potentially explosive atmospheres.
Only manipulate connections in the specified ambient temperature range.
Temperature range: -5 C° ... +70 C°
Danger!
Danger to life from incorrect installation
Incorrect installation of cables and connection lines can compromise the function and the
electrical safety of the device.
Observe the permissible core cross-section of the conductor.
■
When using stranded conductors, crimp wire end ferrules on the conductor ends.
■
Use only one conductor per terminal.
■
When installing the conductors the insulation must reach up to the terminal.
■
Observe the tightening torque of the terminal screws.
■
The following section describes the different connection details of the motherboard with
particular reference to the torques required for a safe installation.
For any terminal connections, observe the following cable and connection information.
Screw Terminals: Cable and Connection Information
Permissible wire core section:
■
- Screw terminals with flexible or rigid wires: 0.2-2.5 mm²
Insulation stripping length: 7 mm
■
If you use stranded connectors: Crimp on wire end ferrules
■
Ensure that connectors are mechanically locked
■
Torque required for tightening terminal screws: 0.4-0.5 Nm
■
Spring Terminals: Cable and Connection Information
Permissible wire core section:
■
- Spring terminals with flexible or rigid wires: 0.5-2.5 mm²
Insulation stripping length: 10 mm
■
Ensure that connectors are mechanically locked
■
Torque required for tightening terminal screws: 0.4-0.5 Nm
■
Tip
Double-check that the correct torques are used when un- and reinstalling the terminal during
wiring activities!
