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 / 88.50 In-Ibs ].

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
/
265.52 In-Ibs ].
4. Check secure fit of all connected cables.
ð The device is connected to the power grid.

Resid. current monitoring (RCMU)
The device is equipped with an all-pole sensitive residual current monitoring unit (RCMU) according to IEC/EN 62109-2
and VDE 0126-1. The RCMU monitors AC- and DC residual currents and disconnects the device redundantly from the pub-
lic grid in the event of residual current steps of > 30mA redundant from the public electricity grid. If the residual current
monitoring unit malfunctions, the device is immediately disconnected from the public grid on all poles. The functionality
of integrated RCMU shall be observed in document 'RCMU Functionality blueplanet 87.0-165TL3' on our homepage.
If local regulations require the use of an external residual current device, the recommendations in the document 'Confir-
mation of compatibility with earth-leakage circuit breakers (RCD) blueplant 87.0-165TL3' on our homepage shall be ob-
served.
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 48]].
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.
