CONNECTION TO POWER MAINS
POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.
THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE
MANUFACTURER’S LABEL.
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED
AND WILL VOID THE WARRANTY.
The unit is designed for connection to power mains with the parameters specified in the "Technical data" section.
The connection must be made using durable, insulated and heat-resistant conductors (cables, wires). The actual wire cross section
selection must be based on the maximum load current, maximum conductor temperature depending on the wire type, insulation,
length and installation method. The fan connection shall be made on the terminal block mounted inside the terminal box in strict
accordance with the wiring diagram and terminal designations. The external power input must be equipped with a QF automatic circuit
breaker built into the stationary wiring to open the circuit in the event of overload or short-circuit. The position of the external circuit
breaker must ensure free access for quick unit power-off. The automatic circuit breaker rated current must exceed the ventilator current
consumption, see the Technical data section or the unit label. It is recommended to select the rated current of the circuit breaker from
the standard series, following the maximum current of the connected unit. The circuit breaker is not included in the delivery set and can
be ordered separately.
