• The tightening torque refers to cable glands installed by the manufacturer:
• Recommended: 3.5 Nm
• Maximum: 10 Nm
• This value may be different depending on the type of cable. However, the maximum value
must not be exceeded.
• Only suitable for fixed installation. The operator must pay attention to a suitable strain relief of
the cable.
• The cable glands are suitable for a low risk of mechanical danger (4 Joule) and must be mounted in
a protected position if larger impact energy levels are expected.
• To maintain the ingress protection of the housing: Install the housing cover, cable glands and blind
plugs correctly.
Cable entry: Electronics compartment
