Disconnect the unit from the power supply prior to any electric work. The power mains connection
shall only be performed by a professional electrician. The nominal 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 takes 230V/50 Hz single-phase alternating current.
The connection must be made using durable, insulated and heat-resistant conductors (cables and
wires) with the minimum section of 2,5 mm
The given wire sections are for reference only. The conductor section selection shall account for
the maximum permissible wire heating which depends on the wire type, its insulation, length and
installation method (i.e. overhead, in pipes or inside the walls). The unit connection shall be made
on terminal block X1 mounted inside the control unit (see Fig. 7) in accordance with the external
connections diagram and terminal designations as shown on Fig. 11 (for PA 01W, PA 02W and PA 03W
units) or on Fig. 12 (for PA 04W unit) according to the air handling unit type.
