The signal words have the following meanings:
NOTICE
indicates a situation which may
result in material damage.
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 category 1/zone
0 and zone 20. Use only in permitted categories/
zones. Use device only in accordance with the oper-
ating conditions defined in the mounting and wiring
instructions. Use device only in accordance with the
intended purpose defined in the mounting and
wiring instructions.
The device complies with the European standards for explosion protec-
tion 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 1 and 2 as well as
zones 21 and 22 according to EN 60079-14. Comply with the require-
ments of EN 60079-14, e.g. with regard to dust deposits and tempera-
ture limits. The device is used in safety circuits 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 at low temperatures. Electric
shock hazard! Mount carefully at low temperatures.
=
DANGER
Untight if mounted without an actuator. Explosion
hazard! Only operate with an actuator.
CAUTION
indicates a situation which may
result in minor or moderate
injury.
DANGER
indicates a situation which will
result in serious injury or death.
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 and EN ISO 14120.
Application and operation
=
DANGER
Live parts. Electric shock hazard! Explosion haz-
ard! 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 appropriate fuse size.
- 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 IP66.
- 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.
