Before connecting, check the installation boxes, plugs and, if present, the terminal box
for possible damage, corrosion, dirt and moisture.
To ensure the degree of protection, ensure that the plug screw connections, the seals
and sealing surfaces of the plugs and the terminal box are seated correctly and protect-
ed.
Note!
To maintain the degree of protection, the turnable connection boxes should not be
changed more than 5 times by turning the knob.
Plug-in and terminal box connections must not be subjected to mechanical stress. If re-
quired provide torsional, tensile and thrust loads as well as a bend protection.
In the case of main connection via the terminal box additionally the following must be consid-
ered:
The cable ends must only be stripped to such an extent that the insulation is close to the
cable lugs or terminals. Absolutely avoid protruding wire ends.
The cable lugs used must correspond to the dimensions and cross-sections of the ter-
minals and cables.
The screw connections of the electrical connections are tightened by the specified tight-
ening torque (refer to
9.2 table 4
/
9.3 table 5
).
The protection degree remains..
Note!
All entries that are not required are closed with metal locking elements. The
sealing elements must be functional and undamaged.
