Translation of the original operating instructions
4.3.1 Preparing connection lines for the connection
Strip the cable just enough so that the screwed cable gland is tight and
the terminals are relieved of strain. Tightening torque, see chapter 3.1
Product drawing.
NOTE
Tightness and strain relief depend on the cable used.
→ The user must check this.

Legend: CL = control lines
4.3.2 Connecting cables with terminals
WARNING
Terminals and connections have voltage even with a
unit that is shut off
Electric shock
→ Wait five minutes after disconnecting the voltage at all poles
before opening the device.
;
Remove the cap from the screwed cable gland.
Remove the cap only in those places where cables are inserted.
;
Mount the screwed cable glands with the seal inserts provided in the
terminal box.
;
Insert the line(s) (not included in the standard scope of delivery) into
the terminal box.
;
First connect the "PE" (protective earth) connection.
;
Connect the lines to the corresponding terminals.
Use a screwdriver to do so.
During the connection work, ensure that no cables splice off.

;
Seal the terminal box.
4.3.3 Cable routing
No water may penetrate along the cable in the direction of the cable gland.
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
(siphon) 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 that the cable is routed in the form of a loop (water trap).
