Safety instructions

• 

The fan must never be carried by the connection cable, terminal box, impeller, guard grille, inlet connection or 

silencer.

• 

In the case of open transport, ensure that no water can penetrate the motor or other sensitive components.

• 

It is recommended that the fan be transported to the installation site in its original packaging. 

Caution: Careless loading or unloading may cause damage to the fan.

• 

Carry out loading or unloading carefully.

• 

Use lifting equipment designed for the load.

• 

Observe the transport arrows on the packaging.

5.  Description

5.1.  GB, GBG and GBV with EC motor

The fans are driven by EC motors. The fans must be controlled with a potentiometer (0-10V). All motors are suitable for 

50/60 Hz. The input voltage for single-phase units is in the range 200V and 277V, for three-phase units the input voltage is 

380 and 480V.

The maximum fluid temperature is +120°C.

Note

When installing EC motors, ensure that RCDs of type class: B or B+ are present in the circuit.
