When making cable terminations inside the enclosure, ensure that the cable length from the
terminal strip/connector to the terminal housing is sufficient so that no strain is placed on the
connector assembly when the housing is in the fully open position.
After making the wiring connections as described in the next section, ensure the nut on the
cable gland is tightened properly to seal around the cable. Ensure that this seal is watertight.
