The supply voltage of the unit must be connected in such a way that all poles of the network are
-
disconnected from the power supply by one element (e.g. main switch). The unit inlet phase must be
connected via a protective power circuit breaker (protective switch) according to the corresponding
current. The minimum distance between the disconnected contacts must be greater than 3mm.
Before installation, check that the cable marking corresponds to the electrical diagram. If you have any
-
doubts, please contact your supplier.
3.6.2. Power and control cables ofthe unit
the unit is equipped with a separate power supply and separate control cable (strand-type cable). Stripping
-
of cables to individual conductors is 80mm. The conductors are equipped with a crimped terminal with
insulation (sleeve).

3.6.3. Description of power and control cables
-
The correct connection and use of all or part of the conductors taken out from the unit is subject to the
selected type of control. The connection of the supply and control wires must be carried out in such a
way that they cannot in any case be interconnected or confused. This would result in the destruction of
the unit fan and possible further damage to the property and health of persons.
