2.
Remove the protective insulation from each of the conductors and fit a suitable
cable end sleeve to the exposed ends of each conductor.
3.
Install the "DC negative" and "DC positive" cables, one after the other. First feed
the negative 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 one of the "DC negative"
connection terminals and tighten the retaining screw firmly (torque 4.0 Nm to
5.7 Nm).
5.
Then insert the positive conductor through the metric-thread cable screw
connection into the "DC positive" terminal of the Sunny Island 3324/4248 and
tighten the retaining screw firmly (torque 4.0 Nm to 5.7 Nm).
6.
Then tighten both of the metric-thread cable screw connections firmly.
No other devices should be connected to the cables connecting the batteries
with the Sunny Island 3324/4248 DC connection. Connection of other DC
devices to the batteries should be done using separate cables leading directly
to the batteries.
