Installation, mounting and 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
Leakage caused by untight cover. Explosion haz-
ard! Risk of burns! Tighten the cover appropriately.
Oberserve tightening torque 0.5 - 0.6 Nm.
=
DANGER
Leakage caused by defective, faulty or incorrectly
installed cable gland. Explosion hazard! Risk of
burns! Install cable gland correctly. Check cable
gland for tightness (min. IP64) where it meets
the cable.
Single-wires must be stripped at least 5 mm, multi-wires must be
stripped at least 5 mm and equipped with 5 mm long conductor fer-
rules. Mount the solenoid interlock and actuator on an even surface.
The solenoid interlock Ex STM 295 has to be fixed with 3 screws for
which 3 fixing holes are provided. The electrical connection may only
be carried out by authorised personnel. They must take care that the
accessibilty of actuators or spare actuators is prevented because of
the danger of manipulation. Ensure that the device cannot be moved
from its position. Ensure this in case of failure, too. For protection
against manipulation use oneway safety screws. With other fastening,
e.g. riveting or welding, ensure that the immersion depth of the coded
actuating bracket does not change. Operational use of the auxiliary
unlocking device must be eliminated by appropriate measures. When
mounting the actuator and switch, observe the requirements of EN
ISO 14119, especially the sections 5.1 to 5.4! Observe the instructions
in the standards EN ISO 12100 and EN ISO 14120.
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 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 IP64.
- 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, service and 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 de-vice in
any way.
=
DANGER
Live parts. Electric shock hazard! Explosion haz-
ard! Open device only while it is in zero
potential state.
=
NOTICE
In all operational life phases of the device, meas-
ures that are constructively and organizationally
suitable for protection against manipulation or
against circumvention of the safety device, e.g. by
using a spare actuator.
With careful mounting as described above, only minor maintenance is
necessary. We recommend a routine maintenance as follows:
1. Check switching function.
2. Check for tight installation of the switch and actuator.
3. Check for alignment of solenoid interlock and actuator.
4. Remove all dirt.
5. Screw and close cover correctly, tightening torque 0.5 ... 0.6 Nm.
