WARNING
Danger due to live metal parts!

If a cable lug connection is used, the live metal parts are located outside the switch.

Make sure that the protection against accidental contact are mounted on the switch
to guarantee ingress protection IP2x!
WARNING
Danger due to twisted cable lug connection!

Due to mechanical load of the cable, the cable lug connection may be twisted on the
clamping plate. The protection against accidental contact guarantees the anti-twist
protection.

Use the switch with mounted protection against accidental contact or separate

anti-twist protection only!
WARNING
Danger due to live metal parts if only one conductor or conductors with a small
cross-section are mounted!

If only one conductor or at least one conductor with a cross-section ( 70 mm

is used,
it is possible to come into contact with live metal parts even if the protection against
accidental contact is mounted since the openings of the protection are not completely
sealed.

To reach the ingress protection IP2X, a suitable cover has to be attached in addition
to the protection against accidental contact.

Allowed cross-section diameters, see tab. 8-1.
