• Lead the connection lines through the cable entries into the enclosure in accordance
EN
with the operating instructions. Make sure that the conductor diameter matches the
EN
nominal diameter of the cable entry.
• Tighten the hexagon nuts of the cable entry firmly such that the tightness of the
EN
enclosure and the strain relief protection at the connection points are guaranteed.
EN
The tightening torques are given in the operating instructions of the components.

• Install the connection lines in such a way that the permissible minimum bending radii
EN
values are not undershot for the respective conductor cross-section and in a way that
prevents mechanical damage to the conductor insulation from sharp-edged or
EN
movable metal parts during installation.

Connection terminals
Tighten the screws of the connection terminals to the specified tightening torque.

Explosion hazard due to insufficient protective measures!
Non-compliance results in severe or fatal injuries.
• Select suitable cables to ensure that the maximum permissible
conductor temperatures are not exceeded.
• When using core end sleeves, attach them using a suitable tool.
• Observe the insulating capacity and separation distances between
intrinsically safe and non-intrinsically safe circuits according to
IEC/EN 60079-14, section 12.
• Use only separately tested cable entries and stopping plugs with
an EU Type Examination Certificate.
• Guide the conductor insulation so that it reaches the terminal.
• Do not damage the conductor when removing the insulation
(e.g. nicking).
• Always connect the protective conductor.
Information regarding the equipotential bonding (PA), earthing (PE)
and intrinsically-safe circuits is given in the documentation of the installed
devices.
