4.5 Connection lead & terminal box
Information
In demanding environments (wet areas, open air installation) all connections must
incorporate water drainage curves. To ensure that water cannot penetrate through to the
controller housing from the connections install a terminal box lower than the motor.
4.6 Assembly in a humid atmosphere
Information
If a fan / motor is stationary for long periods in a humid atmosphere, it should be switched
ON for minimum of two hours every month to remove any moisture that may have
condensed within the motor.

4.7 Assembly of the MAXvent fan
Attention!
•Motor and accessories (protective grille etc.) must be connected to earth.
•Connection points must be reliably protected against the formation of corrosion.
Observe the following points for all types of fans:
•Do not install without suitable supports/brackets.
•Ensure adequate clearance on suction and pressure sides. When installing fans in
devices, ensure there is a suitable inlet opening through a minimum integration
distance, which corresponds to the rough diameter of a fan.
•Warping caused by the elasticity of the components must not cause the impeller to
rub against the tubular housing.
•Ensure that there is a constant gap dimension "a" (see figure below) betweenimpeller
and tubular housing.
•According to EN 14986, the minimum distance between non-moving and moving
parts must be complied with. The distance must not be less than 0.5 % of the
diameter (at least 2 mm and at most 20 mm).
Minimum gap dimension:
fan type a (min.) fan type a (min.)
FV31 / DN31 2.0 mm FV71 / DN71 3.55 mm
FV35 / DN35 2.0 mm FV80 / DN80 4.0 mm
FV40 / DN40 2.0 mm FV90 / DN90 4.5 mm
FV45 / DN45 2.25 mm FV10 / DN10 5.0 mm
FV50 / DN50 2.5 mm FV12 / DN12 6.25 mm
FV56 / DN56 2.8 mm FV14 / DN14 7.0 mm
