Install cable gland for backup connection
Even if you do not wish to use the connection, you must mount the cable gland to the inverter to prevent moisture from entering the inverter.
Procedure:
- Remove the union nut with sealing plug from the M20x1.5 cable gland.
- Insert the cable gland into the hole on the rear of the inverter and tighten it from the inside using the counter nut.
- Tighten the union nut on the cable gland incl. sealing plug hand-tight.
