Install the connections to the Sunny Island 3324/4248 as follows:
1. Install an M20 metric-thread cable screw connection (included in delivery) in
one of the "Additional connections" cable feed-throughs (see figure Page 31).
- Remove the dummy plug covering the chosen cable feed-through in the
housing.
- Insert the cable screw connection thread into the opening in the housing.
- Screw the appropriate M20 counter-nut onto the cable screw connection
thread inside the housing.
2. Remove the protective insulation from the conductors and fit a suitable cable
end sleeve to the exposed ends of each conductor.
3. Feed the conductors through the metric-thread cable screw connection into the
housing of the Sunny Island 3324/4248.
4. Insert the first conductor with the cable end sleeve into one of the "Load_S"
connection terminal and tighten the terminal screw firmly. Then connect the
second conductor to the second "Load_S" connection terminal. The polarity of
the two conductors does not matter.
5. Now tighten the metric-thread cable screw connection firmly.
