DESIGN AND FUNCTIONING The fan casing is made of an aluminium frame, fastened with aluminium angles, and removable heat and sound insulating two-layer aluzinc panels. Due to a casing made of aluzinc with increased corrosion-resistant properties and a heat-insulating material, the fan can be used for outdoor installation.
MOUNTING AND SET-UP BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN OBJECTS (E.G. FOIL, PAPER). WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT MAINTENANCE AND REPAIR. Before installing the fan, make sure that there is no visible damage to the impeller, check the integrity of the insulation of the supply wires. Make sure the impeller rotates freely without touching the flange and the casing.
The terminal designations are shown on the label inside the fan casing. Power supply parameters and examples of wiring diagrams depending on the unit model VS 355 4E VS 400 4E, VS 450 4E VS 500 4E...

A humidity sensor can be connected in the same way. The connection of external control devices in the integrated terminal boxes is carried out on the KL3 terminal blocks in strict accordance with the terminal designation.

current and reduces torque characteristics. This type of regulation is especially suited for turbomachinery such as centrifugal pumps and fans. Regulation by variation of torque optimizes the torque during startup and reduces in-rush current in the circuit. These conditions are suitable for mechanisms with constant load resistance.
