Translation of the original operating instructions

4.3 Connection in terminal box

4.3.1 Preparing cables for connection

Only strip the cable as far as necessary, ensuring that the cable gland is
sealed and there is no strain on the connections. For tightening torques,
see Chapter 3.1 Product drawing.

NOTE
Tightness and strain relief are dependent on the cable
used.

→ This must be checked by the user.

4.3.2 Connecting wires to terminals

WARNING
Live terminals and connections even with device
switched off

Electric shock
→ Wait five minutes after disconnecting the voltage at all poles

before opening the device.

;

Remove the cap from the cable gland.

Only remove caps where cables are fed in.

;

Route the wire(s) (not included in scope of delivery) into the terminal
box.

;

Connect the wires to the corresponding terminals.

Use a screwdriver to do so.
When connecting, ensure that no wire ends fan out.

;

Seal the terminal box.

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.

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