Installation, mounting and dismantling
=
DANGER
Live parts and explosive atmosphere. Electric
shock hazard! Explosion hazard! Risk of burns!
Ignoring this message will lead to serious injuries
or death. Connecting and disconnecting only to be
performed by qualified and authorised personnel.
Connecting and disconnecting only in
non-explosive atmospheres.
=
DANGER
Untight if mounted without an actuator. Electric
shock hazard! Ignoring this message will lead to
serious injuries or death. 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. Due to
the danger of manipulation: Prevent accessibility to actuators and
spare actuators. For protection against unauthorized manipulation,
use e.g. one-way safety screws. These are optionally available. With
other fastening, e.g. riveting or welding, ensure that the immersion
depth of the coded actuating bracket does not change. When mounting
the device, observe the requirements of EN ISO 14119, especially sec-
tions 5.1 to 5.4! TThe 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. 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! Ignoring this
message will lead to serious injuries or death.
Protective cover over contacts must be intact.
=
DANGER
In case of overloaded contacts too high operation
temperatures. Explosion hazard! Risk of burns!
Ignoring this message will lead to serious injuries
or death. For short-circuit protection use fuse size
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).
Cleaning
=
DANGER
Live parts. Electric shock hazard! Ignoring this
message will lead to serious injuries or death.
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.
Maintenance, repair and service
=
DANGER
Live parts. Electric shock hazard! Ignoring this
message will lead to serious injuries or death. Do
not repair defective or damaged devices. Replace
them.
=
DANGER
Explosive atmosphere. Explosion hazard! Risk of
burns! Ignoring this message will lead to serious
injuries or death. Observe maximum switching
cycles.
=
DANGER
Explosive atmosphere. Explosion hazard! Risk of
burns! Ignoring this message will lead to serious
injuries or death. Do not rebuild or modify the de-
vice in any way.
With rough conditions, we recommend routine maintenance as follows:
1. Check actuator for easy operation.
2. Check the switchgear for damage.
Damage can influence the explosion protection!
Damaged switchgear must be replaced!
3. Remove all dirt.
4. Check sealing of the cable or conduit connections.
Disposal
- Observe national, local and legal regulations concerning disposal.
- Recycle each material separately.
N.B.
Do not use the device as a mechanical endstop. Any mounting position
is possible. Reconstruction and alterations to the device which might
affect the explosion protection are not allowed. Furthermore, EN
60079-14 has to be applied for the installation of electrical equipment
in explosive areas. The described products were developed in order to
assume safety functions as part of an entire plant or machine. A com-
