altered. The adjustment of the ball catch (ordering suffix -2053) should
be done after mounting of the safety switch. Please adjust screws at
both sides with the same number of turns with a screwdriver.
When
mounting the actuator and switch, observe the requirements of
EN 14119, especially the paragraphs 5.1 to 5.7!
Observe the instruc-
tions in the standards EN ISO 12100 and EN ISO 14120.
Application and operation
- Use device only within the permitted electrical load limits (see
technical data).
- For short-circuit protection, use fuse size 3 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 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.
Disposal
- Observe national, local and legal regulations concerning disposal.
- Recycle each material separately.

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 switching function.
2. 2. Check for tight installation of the switch and coded actuator
3. Remove all dirt.
4. Screw and close cover correctly, torque 0.5 … 0.6 Nm.
5. Check sealing of the cable or conduit connections.
N.B.
Do not use the device as mechanical endstop. Any mounting position is
possible. It should be selected in such a way that no coarse dirt can
fall into the used slot. It should be selected in such a way that no
coarse dirt can fall into the used slot. The unused slots should be pro-
tected with the optional slotcaps (AZ 15/16-1476 is available as an ac-
cessory). Reconstruction and alterations to the device which might af-
fect the explosion protection are not allowed. Furthermore, EN 60079-
14 has to be applied for the installation of electrical equipment in haz-
ardous areas. Moreover, the ATEX test certificate and the special con-
ditions therein have to be observed. The described products have been
developed in order to assume safety functions as a part of an entire
plant or machine. A complete safety system normally covers sensors,
monitoring modules, indicator switches and concepts for safe discon-

Only for use in category 3/zone
22. Use device only in accordance with the operat-
ing 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 and EN 60079-31. It is intended for use in hazardous
areas of zone 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 2 and
EN 60947-5-1.
Special conditions, »X« marking
- Only »Ex« approved and certified cable glands may be used with
minimum IP67 degree of protection.
- If the device is installed in hazardous areas of group IIIC: exclude
strongly charge generating processes.

Mount the safety switch and the actuator on an even surface. The
electrical connection may only be carried out by authorised person-
nel. They must take care to prevent the accessibilty of actuators or
spare actuators because of the danger of manipulation. There are
three cable entries M20 x 1.5 which can be broken open at the required
position. Opened and unused cable entries must be closed by »Ex« ap-
proved and certified blank plugs with minimum IP67 degree of protec-
tion. Please ensure that, even in case of failure, the switch cannot be
moved from its position. For protection against manipulation, use one-
way safety screws which are optional available. Ensure with welding or
riveting of the actuator, that the insertion depth of the actuator is not
