WARNING
indicates a situation which may
result in serious injury or death.
Intended use
=
DANGER
Misuse and explosive environment. Explosion haz-
ard! Risk of burns! Not for use in zones 0 and 1
and zones 20 and 21. Use only in permitted zones.
Use device only in accordance with the operating
conditions defined in the mounting and wiring in-
structions. Use device only in accordance with the
intended purpose defined in the mounting and wir-
ing instructions.
The device, design similar to DIN EN 50047, complies with the Europe-
an standards for explosion protection EN IEC 60079-0, EN 60079-1,
EN IEC 60079-7 and EN 60079-31. It is intended for use in hazardous
areas of zones 2 and 22 according to EN 60079-14. Comply with the re-
quirements of EN 60079-14, e.g. with regard to dust deposits and tem-
perature limits. The device is used in safety circuits to monitor the po-

EN 60947-5-1.
Installation, mounting, dismantling
=
DANGER
Live parts and explosive atmosphere. Electric
shock hazard! Explosion hazard! Risk of burns!
Connecting and disconnecting only to be performed
by qualified and authorised personnel. Connecting
and disconnecting only in non-explosive
environment.
CAUTION
indicates a situation which may
result in minor or moderate
injury.
DANGER
indicates a situation which will
result in serious injury or death.
=
DANGER
Untight if mounted at low temperatures. Electric
shock hazard! Mount carefully at low temperatures.
=
DANGER
Untight if mounted without an actuator. Electric
shock hazard! Only operate with an actuator!
=
DANGER
Leakage caused by untight cover. Explosion haz-
ard! Risk of burns! Tighten the cover appropriately.
Oberserve tightening torque 0.4-0.5 Nm.
Mount the device on an even surface. If the turning angle of the guard
door is directly fixed to the cam of the device, the guard door opens at
7° cam travel. Please observe: The wider the guard door, the bigger
the opening of the guard door! Mount the device in such a way that the
cam and the door hinge are in one line. After fixing the device, carry
out the positive linkage between cam and guard door. Therefore, use
the offset positioned boreholes in the cam. Ensure that the device can-
not be moved from its position. Ensure this in case of failure, too. For
protection against unauthorized manipulation, use e.g. one way safety
screws. These are optionally available. When mounting the device,
observe the requirements of EN 14119, especially the paragraphs 5.1
to 5.4! Observe the instructions in the standards EN ISO 12100 and
EN ISO 14120.
Application and operation
=
DANGER
Live parts. Electric shock hazard! Protective cover
over contacts must be intact.
=
DANGER
In case of overloaded contacts too high operation
temperatures. Explosion hazard! Risk of burns! For
short-circuit protection, use fuse size
3 A/6 A (gG/gN).
- Use device only within the permitted electrical load limits (see
technical data).
- Use device only within the permitted ambient temperature range
(see product label and technical data).
- Use only Ex approved and certified cable glands which meet at least
the degree of protection IP66/IP67 and are suitable for the corre-
sponding explosion protection and for the temperature range.
Special conditions / »X« Marking
- Install the device protected against impacts (max. impact energy 4 J).
