Operating instructions

A4E420-AU03-01

Translation of the original operating instructions

4.3.3 Cable routing

Water must be prevented from reaching the cable gland along the cable.

NOTE
Damage caused by moisture penetration.

Moisture can penetrate into the terminal box if water is
constantly present at the cable glands.
→ To prevent the constant accumulation of water at the cable

glands, the cable should be routed in a U-shaped loop
wherever possible.

→ If this is not possible, a drip edge can be produced by

fitting a cable tie directly in front of the cable gland for example.

Fans installed lying flat

Make sure the cable is routed in a U-shaped loop.

Fans installed upright

When routing the cable, make sure that the cable glands are located at
the bottom. The cables must always be routed downward.
