3. Install and operate the device.
Selection and installation of devices and their integration in control
systems demand qualified knowledge of all the relevant laws, as well
as the normative requirements of the machine manufacturer.
In case of doubt, the German language version of these instructions
shall prevail.
Scope of delivery
1 device, 1 mounting and wiring instructions, carton.
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.
CAUTION
indicates a situation which may
result in minor or moderate
injury.
WARNING
indicates a situation which may
result in serious injury or death.
DANGER
indicates a situation which will
result in serious injury or death.
Intended use
=
DANGER
Misuse and explosive environment.
Explosion
hazard!
Risk of burns!
Not for use in categories 1
and 2/zones 0 and 1 and zones 20 and 21. Use only
in permitted categories/zones. Use device only in
accordance with the operating conditions defined
in the mounting and wiring instructions. Use device
only in accordance with the intended purpose de-
fined in the mounting and wiring instructions.
The device complies with the European standards for explosion protec-
tion EN 60079-0, -1, -7, -18 and -31. It is intended for use in hazardous
areas of zones 2 and 22 according to EN 60079-14. Comply with the re-
quirements of EN 60079-14, e.g. with regard to dust deposits and tem-
perature limits. The Ex STM 295-3G/D solenoid interlocks secure that
movable protective guards such as fences, doors or covers in combina-
tion with the control circuitry of a machine, such as safety timers or
standstill monitors, cannot be opened until dangerous situations (e.g.
over-run movements) have been terminated.
There are two versions available:
1. Spring-to-lock principle: lock by spring, unlock by power supply of
electromagnet.
2. Power-to-lock principle: lock by power supply of electromagnet, un-
lock by spring.
This version may only be applied after careful risk
analysis because in case of power failure, immediate access
is given.
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.
If no external fuse with min. 1,500 A switching capacity is connected,
the maximum possible short-circuit current of the supply source
must be limited to a switch-off capacity of the internal fuse to 50 A.
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 295-3G/D 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).
