The electric connection of the fan is carried out in accordance with the operating mode (single-phase or three-phase) according to the connection diagram. The connection diagram is indicated on the cover of the Wistro terminal box. The cables must be provided with insulated plug terminals. If necessary, the fan can be protected by an external protective device (for example, an engine protection switch).
The Wistro terminal box is protected by a casing on the b side of the forced ventilation unit and can be rotated 90 degrees due to its square shape. Installation/disassembly of the fan can be carried out using conventional tools without the help of qualified personnel. The protection class is guaranteed even with side voltage on the power cable.
Advantages:
- There is no need for special tools (for example, crimping pliers), since installation is carried out using screw terminals;
- The motor is connected to a standard terminal box (single-phase and three-phase connection is possible);
- Protection class IP66;
- The possibility of replacement without qualified personnel;
- Significantly low costs and high functionality.
