7.5.2 Making the grid connection
4-pole connection, TN, TT system
↻ Grid connection is prepared.
1. Loosen nut and lock washer at the marked grounding point.
2. Lay the grounding cable onto the grounding point. Secure it with the nut and
lock washer provided [ W_17 /
3. Place the cable lug of cores L1 / L2 / L3 on the busbar in accordance with the la-
beling and secure it with a nut, screw and lock washer (fastening elements in
scope of supply) [ W_17 /
4. Check secure fit of all connected cables.
ð The device is connected to the power grid.
Residual current monitoring unit (RCMU):
The device is equipped with an AC/DC-sensitive residual current monitoring unit in accordance with IEC/EN 62109-2 and
VDE 0126-1. The AC/DC-sensitive residual current monitoring unit monitors AC and DC residual currents and redundantly
disconnects the device from the grid in the event of residual current jumps of > 30 mA. In the event of a malfunction in
the residual current monitoring unit, all poles of the device are immediately disconnected from the public grid. The func-
tionality of the integrated RCMU is described in the document 'RCMU functionality +device type' on our website.
If local regulations require an external residual current circuit breaker (RCD), the recommendations in the document
"Confirmation of compatibility with residual current circuit breakers (RCD)" on our website must be observed.
NOTE
Observe the general earthing recommendation of the existing mains system.
NOTE
If an external residual current circuit breaker is necessary due to the installation specification, a type A residual
current circuit breaker must be used.
If the type A is used, the insulation threshold must be set to greater than/equal to (≥) 200 kOhm in the "DC pa-
rameters" menu [see [See section 9.4.2} Page 53]].
For questions regarding the appropriate type, please contact the installer or our KACO new energy customer
service.

If the connection is made in a TN-C grid, connect the PEN grounding cable to the ground earthing point.
