! Disconnect the equipment from power (unplug from the wall socket) before beginning
any installation work.

any work on the equipment that affects this cable gland.
Use a torque wrench and tighten the cable gland to 5 Nm.
§ Prepare and install the cable as follows.
– Guide the cable through the cable gland.
– Close and tighten the cable gland in accordance with the applicable regulations.

have contact with the clamps (2).
– Expose approximately 15 cm (4 inches) of the wires (3) for connection to the terminals.
– Guide the cable through the cable gland.
– It is important to make sure that the shield is in contact with the clamps, because the

of the isolated wires for installation.
– Remove the casing from approximately 1 cm (1/2 inch) of the wires and attach ferrules to
