6.2.3 Connection
There is a "DC —" and a "DC +" connection available for each ring cable lug (max. 70
mm²) for the battery feed cables in the Sunny Island 5048.
Install the DC connections in the following sequence:
1.
First sheathe the cable screw connection over the cables and then insert the cables
into the housing of the Sunny Island 5048.
2.
Install an M25 metric-thread cable screw connection (included in delivery) on the
"DC —" and "DC +" cable feed-through.
- Insert the cable screw connection thread into the cable feed-through opening.
- Screw the counter nut onto the cable screw connection thread inside the
housing and tighten it.
3.
Remove the protective insulation from each conductor and fit a suitable ring cable
lug to the exposed end of the conductor.
If no cable protection exists, then the DC cables must be protected against
ground faults and short circuits. The internal DC fuse of the Sunny Island
5048 is designed such that it can interrupt currents of up to 10000 A.
For short-circuit currents greater than 10000 A, an additional thermal fuse
is absolutely essential ("SI-BattCase.01-250").
Only connect the external fuse/battery cables to the battery after all other
installation work is finished.
