4.3 Connecting the cables
The device has external leads.
●
Connect the cables according to your application. When doing so,
observe Chapter 4.4 Connection diagram.
4.3.1 Cable routing
Water must be prevented from reaching the cable exit 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.
