In case of inadequate or improper use or manipula-
tions of the device, personal hazards or damage to
machinery or plant components cannot be exclud-
ed.
Warning about misuse!
Observe
the relevant
instructions of EN ISO 14119.
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 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 Ex STM 295 solenoid
interlocks secure that movable protective guards such as fences,
doors or covers in combination 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 terminat-
ed.
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.
Special conditions and »X« marking
If no external fuse with min. 1,500 A switching capacity is connected,
limit the maximum possible short-circuit current of the supply source
to a switch-off capacity of the internal fuse to 50 A.
