damage
ATTENTION!
Electro-magnetic interferences can lead to malfunctions of the
control device and to destruction of the components!
The control device is permitted for operation at home and at commercial
facilities. Operation under different electro-magnetic conditions can lead
to damage or malfunctions.
Malfunctions due to electro-magnetic interferences are disturbances,
which affect the device from outside.
Pay attention to the following points:
– Lay the signal cables separate from the power supply cables and
cables to the electrical consumers.
– Electrical consumers like e.g. illuminants, pumps, relays and
contactors, which are connected to the control device should not emit
impermissibly high interferences. If you connect inductors like e.g. a
magnet valve, relay, transformer, throttle or engine, the interferences
of the consumers must be suppressed.
6.2 Connecting the control device, consumers and sensor
1. Connect the power line to the sauna control as per the electrical circuit diagram.
2. Connect the 203/400V consumers to the sauna control as per the electrical circuit
diagram.
3. Connect the sensor to the sauna control as per the following figures.
4. Place the shielding on the PE as per the circuit diagram. Do not place the shielding
on the PE if there are disturbances/interferences.
In this process pay attention to the following points:
Observe the technical data for power lines, cables to the electrical consumers and the
signal cables.
Lay the cables in such a way that they are not accessible to the user of the cabin. If this
is not possible then the cables should be provided with cord grip.
Lay all the neutral cables on the bus bar N.
Lay all the grounding conductors on the bus bar PE.
