Vents-us VKP 100, User Manual

DISCONNECT THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.

CONNECTION OF THE UNIT TO POWER MAINS IS ALLOWED BY A QUALIFIED 

ELECTRICIAN WITH A WORK PERMIT FOR THE ELECTRIC UNITS UP TO 1000 V AFTER 

CAREFUL READING OF THE PRESENT USER’S MANUAL.

THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE 

MANUFACTURER’S LABEL. 

•  The unit is rated for connection to 1~120 V/60 Hz power mains. 
•  The unit must be connected to power mains using insulated electric 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 external power input must be equipped with an automatic circuit breaker built into the stationary wiring to open the electric circuit 

in case of overload or short-circuit. The circuit breaker installation place must provide quick access for emergency shutdown of the unit. 
The trip current of the automatic circuit breaker QF must exceed the maximum current consumption of the unit (refer to the technical 
data table).  The recommended trip current of the circuit breaker is the next current in the standard trip current row following the 
maximum current of the connected unit.  The automatic circuit breaker is not included in the delivery set. 

To connect the fan to the power network it is necessary to:
- shut off the power network (Pic.12);
- remove the cover from the terminal box (Pic.13);
- remove the clamping bar (Pic. 14);
- lay out the cables through the terminal box lug, remove the insulation from the cables ends for ¼ of an inch (6-7mm) length, connect them 
to proper terminals up to the stop of insulation and fix with screws (Pic.14);
- place back the clamping bar, tighten up the lug and install the cover on the terminal box (Pic.15).
