Intended use
=
DANGER
Misuse and explosive environment. Explosion haz-
ard! Risk of burns! Not for use in categories 1 and
2/zones 0 and 1 and zones 20 and 21. Use only in
permitted categories/zones. Use device only in ac-
cordance with the operating conditions defined in
the mounting and wiring instructions. Use device
only in accordance with the intended purpose de-
fined in the mounting and wiring instructions.
The device complies with the European standards for explosion protec-
tion EN 60079-0, -1, -7 and -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. Devices with a positive break A are used in safety cir-
cuits to monitor the position of mobile safety guards to EN ISO 14119
(EN 1088) type 1 and 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.
=
DANGER
Untight if mounted without an actuator. Electric
shock hazard! Only operate with an actuator.
Mount the device on an even surface. Ensure that the device cannot be
moved from its position. Ensure this in case of failure, too. For protec-
tion against unauthorized manipulation, use e.g. one-way safety
screws. These are optionally available. The enclosure is equipped with
two terminals for a protective conductor: one inside the enclosure for
a wire cross-section of max. 1.5 mm² and an external one for max.
4 mm² wire. To avoid electrostatic charging: include the device in the
equipotential bonding (earthing) via the internal or external protective
earth conductor. Observe the instructions in the standards EN ISO
12100, EN ISO 14120 and EN ISO 14119.
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 1.5 A or
6 A (gG/gN), see product label.
- 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).
Cleaning
=
DANGER
Live parts. Electric shock hazard! When cleaning:
observe degree of protection IP67.
- Use a damp cloth to clean devices in explosive areas. This prevents
electrostatic charge.
- In case of damp cleaning: use water or mild, non-scratching,
non-chafing cleaners.
- Do not use aggressive cleaners or solvents.
Disposal
- Observe national, local and legal regulations concerning disposal.
- Recycle each material separately.
Maintenance, service, repair
=
DANGER
Live parts. Electric shock hazard! Do not repair de-
fective or damaged devices. Replace them.
=
DANGER
Explosive atmosphere. Explosion hazard! Risk of
burns! Observe maximum switching cycles.
=
DANGER
Explosive atmosphere. Explosion hazard! Risk of
burns! Do not rebuild or modify the device in
any way.
With rough conditions, we recommend routine maintenance as follows:
1. Check actuator for easy operation.
2. Remove all dirt.
3. Check sealing of the cable or conduit connections.
N.B.
Do not use the device as mechanical endstop. Any mounting position is
possible. Reconstruction and alterations to the device which might af-
fect the explosion protection are not allowed. Furthermore, EN 60079-
