Procedure:
2. Open the inverter (see inverter installation manual).
3. Push one filler plug from the inside out of the bottom of the inverter enclosure.
4. Attach the cable gland to the enclosure opening
using the counter nut. Ensure that the grooved side of
the counter nut is facing the inverter enclosure.
5. Gauge the length from the communication terminal to the counter nut on the cable gland using
the cable, and mark the position on the cable. Be sure to take the permitted cable route into
account (see Section 5.1).
6. Below the marked position, remove 20 mm from the
cable sheath. This will enable contact between the
screening clamp and the cable shield in the cable
gland.
7. Unscrew the swivel nut of the cable gland but do not remove it.
