DANGER!
Danger to life due to electric potential
Use of inappropriate cables can lead to short circuits and subsequent
fires.
Damage to the insulation can be dangerous to life.
Therefore:
– All the cables, which lead to the sauna, must be designed for at least
150 °C.
– Use cables as per specifications in Table 1 and electrical circuit
diagram (see annexure). The specified cross sections are designed
for copper cables. In case of aluminum cables the cross sections
should be appropriately increased.
– The cross sections can increase due to the length of the cables, the
type of cable laying or special regulations.

The patch cable can be delivered with a standard length of 5 or 10m. If
another length is desired then the cable must be configured by the
electrician
. Another option would be to bridge a stretch by installing two
network sockets (CAT 5).
