If there is no grounding system in the building where the device is installed, a
grounding line must be installed by qualified personnel. Periodical checks should be
carried out to ensure that the grounding installation is in working condition. The fuse
should be located sufficiently close to the device so that the cable coming out of the
device can be connected to it without tension. Connection of cables to fuses should
be done by qualified personnel.
Make sure you connect the cables to the right place.
Loose cable connections can cause accidents.
Cable sections, residual current relay, and fuse ampere values, calculated
according to device capacity and cable lengths can be seen in the table below.
The cable cross-sections in this table are calculated for a maximum of 10 m.
For cable lengths longer than 10 m, consult your electrician.
