Safety information
=
In this document, the warning triangle is used
together with a signal word to indicate a
hazardous situation.
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 60079-0, -1 and -31. It is intended for use in explosive hazard-
ous areas of zones 1 and 2 as well as zones 21 and 22 according to EN
60079-14. Comply with the requirements of EN 60079-14, e.g. with re-
gard to dust deposits and temperature limits. The device is applied on
machines and plants where an emergency-stop command is required
along the complete pull-wire. Pulling or breaking the pretensioned
wire triggers the switching function of the emergency pull-wire switch
and thus lead to contact latching. The reset can only be carried out
manually by unlocking with the push-button.
Special conditions and »X« marking
- The device's connection cables must have a fixed installation and be
set up in a manner that protects them from mechanical damages.
- If the connection is in an explosive area, the connection cable has to
be connected in an enclosure which complies with the requirements
of an approved ignition protection degree according to EN 60079-0,
par. 1.
CAUTION
indicates a situation which may
result in minor or moderate
injury.
DANGER
indicates a situation which will
result in serious injury or death.
Installation, mounting, dismantling
=
DANGER
Live parts and explosive atmosphere. Electric
shock hazard! Explosion hazard! Before commis-
sioning, check device for correct installation. Com-
ply with national regulations.
=
DANGER
Live parts. Explosive atmosphere. Electric shock
hazard! Risk of burns! Connecting and disconnect-
ing only to be performed by qualified and author-
ised personnel. Connecting and disconnecting only
in non-explosive environment.
Before mounting the pull-wire, remove the red PVC sheath from the
the pull-wire in the clamping range of the pull-wire (see »Mounting
notes wire thimbles«)! After fitting the wire, pull strongly on it several
times, as the pull-wire and the wire thimble will deform. Subsequently,
retense the wire using the DUPLEX wire clamp, eye-bolt or tensioner.
Application and operation
- Use device only within the permitted electrical load limits (see
technical data).
- For short-circuit protection, use fuse size 6 A (gG/gN).
- Use device only within the permitted ambient temperature range
(see product label and technical data).
Cleaning
- Use a damp cloth to clean devices in explosive hazardous 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.
Service, maintenance, repair
=
DANGER
Live parts. Explosive atmosphere. Electric shock
hazard! Explosion hazard! Risk of burns! Do not
repair defective or damaged devices. Replace them.
Do not rebuild or modify the device in any way.
With careful mounting as described above, only minor maintenance is
necessary. We recommend a routine maintenance as follows:
1. Check pull-wire function.
2. Removal of dirt.
3. Check sealing of the cable or conduit connections.
Disposal
- Observe national, local and legal regulations concerning disposal.
- Recycle each material separately.
