2. Connect the telephone cable to the front side of the control panel. Attach the front side of the control panel to its back side using the supplied countersunk head screws as shown below. Press the control panel front side to click to complete installation.

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.

• The unit is rated for connection to single-phase 230 V/50 Hz or three-phase 400 V/50 Hz power mains (refer to Technical data) in compliance with wiring diagrams.
• The unit must be connected to power mains using durable, insulated and heat-resistant conductors (cables and wires). The actual wire cross section selection must be based on the maximum load current, maximum conductor temperature depending in the  wire type, insulation, length and installation method.
• The external power input must be equipped with an automatic circuit breaker QF built into the stationary wiring to open the circuit in the event of overload or short-circuit. The position of the external automatic circuit breaker must ensure free access for  quick poweroff of the unit.
  The trip current of the automatic circuit breaker must exceed the maximum current consumption of the unit (refer to the “Technical data” section). 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 and can be ordered separately.

ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY.
DO NOT LAY THE VENTILATION UNIT POWER CABLE IN CLOSE PROXIMITY TO THE CONTROL PANEL CABLE!
DO NOT COIL THE CABLE FROM THE CONTROL PANEL IN LOOPS WHILE LAYING IT.

Route the cables to the control unit via the cable glands on the air handling unit.
Complete the electric connections in compliance with external wiring diagram via the terminal blocks in the control unit.
