8.2 External wiring
Lead the connecting wires with intact external insulation jackets through the cable entries
into the terminal compartment.
Please ensure that the cable diameter and the terminal cross section on the cable entry
are identical.
Tighten the hexagon nut of the cable entry so that the sealing of the terminal
compartment as well as the strain relief at the connection point are guaranteed. To
determine the tightening torques, please consult the operating instructions of the
individual components.
Lay the connecting wires in the terminal compartment so that:
X The minimum permissible bending radii for the respective conductor cross section are
achieved.
X No mechanical damage to the conductor isolation rubbing against sharp-edged metal
parts result.
Terminals
Tighten the screws of the connection terminals in accordance with the specified
tightening torques.
WARNING
Incorrect installation!
Z
Risk of severe injuries.
X
Please observe the thread sizes for the cable glands specified in the
equipment documentation.
X
The connecting cable should comply with relevant regulations and have
the required cross-section. The diameter must be identical to the data on
the cable entry.
X
Ensure that the maximum permissible conductor temperatures are not
exceeded by suitable selection of cables and means of running them.
X
The permissible ambient temperature around the intrinsically safe units
and components must not be exceeded.
X
When stripping insulation, it must be ensured that the conductor insulation
reaches right up to the terminals.
X
The conductor itself must not be damaged when removing the insulation.
X
The switching device combination must only be installed in a dry and clean
environment.
