WIRING STEPS FOR THE S-Vent FAN
• Make sure the power cable is disconnected from power supply (Fig. 1).
• Take off the lid of the terminal box located on the motor casing (Fig. 2).
• Route the power cable wires through the cable gland on the terminal box, then strip the wires for 7-8 mm (Fig. 3).
• Connect the wires to the terminal box in compliance with the wiring diagram and considering the terminal marking. The three-phase
motors must be star-connected (Fig. 3 und 4). For doing that insert the wires into the metal part of the terminals against insulation
stop and fix those with the screws.
• Cover the terminal box with the lid (Fig. 4).

The air direction must match the pointer direction of the fan casing.
To check the impeller direction turn the fan on for a short run.
If the impeller rotation is wrong, change any two phase conductors on the motor terminals. For that change the respective wires on the
terminal block in the terminal box.
