Installation of the grounding conductors occurs in five steps:
1. Install an M25 metric-thread cable screw connection (included in delivery) in the
"Grounding" cable feed-through (see figure Page 31).
- Remove the dummy plug covering the cable feed-through.
- Insert the metric-thread cable screw connection into the opening in the
housing.
- Screw the counter-nut onto the cable screw connection thread inside the
housing.
2. Remove the protective insulation from the conductor and fit a suitable cable end
sleeve to the exposed end of the conductor.
3. Feed the grounding conductor through the metric-thread cable screw connection
into the housing of the Sunny Island 3324/4248.
4. Insert the conductor with the cable end sleeve into the ground connection
terminal and tighten the screw firmly (torque 4.0 Nm to 5.7 Nm).
5. Then tighten the metric-thread cable screw connection.
