Connecting the DC cable to the DC switch
NOTE: For installation of the DC cables, use a torque wrench as well as the in-
cluded open-ended wrench for counter-resistance.
1 Pre-fit DC cable pair with the pre-installed screw and counternut onto the DC+
and DC busbar of the DC switch.
2 Option for 2 cable pairs: Insert spacer sleeve between 2 DC cables and pre-as-
semble in pairs with the provided screws and counternuts onto the DC+ and DC
busbar of the DC switch.
3 Slide the DC input plate up onto the housing base and secure. [

4.5 Inserting the overvoltage protection
Information on the overvoltage protection: See
verter/manual" category.
4.6 Creating equipotential bonding
NOTE
Depending on the local installation specifications, it may be necessary to earth the device with a second
ground connection. To this end, the threaded bolt on the underside of the device can be used.
↻ The device has been installed on the mount.
1 Strip the insulation from the equipotential bonding cable.
2 Furnish the stripped cable with an M8 ring cable lug.
