4.3 Connection in terminal box
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.
4.3.2 Connecting cables with terminals
; Remove the cap from the screwed cable gland.
Remove the cap only in those places where cables are inserted.
; 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.
; Connect the thermal overload protector (TOP).
Use a screwdriver to do so.
During the connection work, ensure that no cables splice off.
The terminal strip is equipped with a penetration prevention device.
; Insert the strands until they meet resistance.
; Seal the terminal box.
4.3.3 Cable routing
No water may penetrate along the cable in the direction of the cable gland.
Fans installed lying flat
Make sure that the cable is routed in the form of a loop (water trap).
Ill. 2: Fan installed lying flat, cable routed as a water trap.
Fans installed in upright position
When routing the cable, ensure that the screwed cable glands are
arranged at the bottom. The cables must always be routed downwards.
