The tightening torques apply to the terminal screws of all electrical connections on the de-
vice. The values specified for the battery circuit breaker are calculated maximum values.
This means that the battery circuit breaker used must trigger no later than when reaching
this amperage.
It is recommended to use a two-pole circuit breaker between solar module and solar
charge controller.
In this way, the solar modules can be connected to or disconnected from the solar charge
controller without voltage, and no electric arcs will form at the terminals.
NOTE
If the solar module is connected to the battery connections, the solar charge
controller may be damaged.
Connect the cables correctly.
Ensure correct polarity by measurement of voltage on the cables prior to con-
nection.
Observe the connection order described below to ensure correct operation of
the solar charge controller.
Proceed in inverse order for uninstalling.
1. Ensure that all cables to the solar charge controller are without voltage due to the
open isolating device (solar module circuit breaker or battery fuse).
2. Strip all cables on the connection side and provide with ferrules if necessary:
- 30 A version: 10 mm
- 50 A version: 18 mm
