§
Connect the cable inside the housing as follows:
– Route the cable through the cable gland.
– Close and tighten the cable gland in accordance with the applicable regulations.
– Strip the casing from a section of the cable end (see illustration). The shielding (1)
must have contact with the clamps (2).
– Expose approx. 15 cm (6 inches) of the individually isolated wires (3) for installation.
– Route the cable through the cable gland.
– Make sure the shield is in contact with the clamps, because the cable is grounded
by the shield.

Connecting the wires inside the indicator:
– Expose approximately 5 cm (2 inches) of the isolated wires for installation.
– Remove approximately 1 cm (1/2 inch) of the isolation from the wires and affix ferrules
to the wire ends.
