Safety instructions
The operations must be carried
out by electrical suitably trained
in hazardous area with knowledge
of increased safty explosion protection
IEC 60079-14.
The safety switches are not suitable for
zone 0, 1, 2 and Zone 0, 21 hazardous
areas.
The requirements of the EN 60079-0 and
EN 60079-31 regarding excessive dust de-
posits and temperature to be considered
from the user.
The temperature class and explosion
group marked on the apparatus, shall be
observed.
The requirements of the EN 60079-0
regarding excessive dust deposits and
temperature to be considered from the
user.
To ensure adherence to the temperature
class stated on the type label of the ap-
paratus, the permissible ambient tempe-
rature, the rated terminal cross section
and the self-heating of the apparatus,
that is mainly due to the power dissipa-
tion, shall be taken into account (test cri-
terion for the self-heating is an overload
of 10%).
Prior to being put into operation, the
safety switches shall be checked in ac-
cordance with the instructions as per
section 6.
Before initial operation, any foreign mat-
ter shall be removed from the apparatus.
The covers of the safety switches can
only be removed when the switch is in
the “ON” position.
Modifications to the switches or changes
of its design are not permitted!
The switches are shall be operated as in-
tended and in undamaged and perfect
condition!
Die Mindestanschlussquerschnitte der
Komponenten sind beim Anschluss
gemäß EN 60 947-1 bzw. dieser Betriebs-
anleitung zu beachten.
For replacing components, only genuine
CCH/CEAG spare parts may be used!
Repairs that affect the explosion protec-
tion, may only be carried out byCCH/
CEAG or a qualified “electrician”!
The national safety rules and regulations
for the prevention of accidents, as well
as the safety instructions included in
