Only if the information described in this operating instructions
manual are realised correctly, the safety function and
therefore the compliance with the Machinery Directive and
the Explosion Protection Directive is maintained.
2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Purpose
The solenoid interlock has been designed to prevent in conjunction
with the control part of a machine, movable safety guards from being
opened before hazardous conditions have been eliminated. The
components can be used in explosion-endangered areas of Zone 22
equipment category 3D. The installation and maintenance requirements
to the standard series EN 60079 must be met.
Conditions for safe operation
Due to the specific impact energy, the components must be fitted
with a protection against mechanical stresses. The specific ambient
temperature range must be observed. The user must provide for a
protection against the permanent influence of UV rays.
Solenoid interlocks with power to lock principle may only
be used in special cases after a thorough evaluation of
the risk of accident, since the safety guard can be opened
immediately on failure of the power supply or upon activation
of the main switch.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required safety
level.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.

3. Mounting
3.1 General mounting instructions
Fitting is only authorised in a de-energised condition.
The enclosure must be mechanically protected.
Four mounting holes are provided for fixing the enclosure. The use of
a protective ground wire is imperative. The enclosure must not be used
as an end stop. Any mounting position. The mounting position must be
chosen so as to avoid the penetration of dirt in the used holes.
Please observe the recommendations regarding maximum
impact energy, actuating speed and tightening torque in the
technical data. The distance between the actuator flange and
the switch enclosure must be < 3 mm when the actuator is
inserted.
Mounting of the actuators: See mounting instructions actuators.
The actuators AZ/AZM 415-B1, -B2 and -B3 are authorised for use in
conjunction with the EX-AZM 415.
Please observe the relevant requirements of the standards
ISO 12100, ISO 14119 and ISO 14120.
4. Rear side Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by
authorised personnel in a de-energised condition.
The contact labelling can be found in the wiring compartment of the
switch.
If the risk analysis indicates the use of a monitored interlock
they are to be connected in the safety circuit with the contacts
indicated with the symbol .
Cable glands (included in delivery) are only authorised for permanent
cables. The constructor must provide for the necessary strain relief. The
conductors of the connecting cables must not obstruct the movement of
the switching lever. Unused openings must be sealed with EX-certified
locking screws (included in delivery).

5. Set-up and maintenance
5.1 Functional testing
The safety function of the safety components must be tested.
The following conditions must be previously checked and met:
- The installation is executed according to the instructions
- The connection is executed correctly
- The cable is correctly executed and connected
- The safety component is not damaged
- Remove particles of dust and soiling
- Check cable entry and connections
5.2 Maintenance
In case of correct installation in accordance with the instructions
described above, the component requires little maintenance. For use in
extreme conditions, we recommend routine maintenance including the
following steps:
1. Check the correct fixing of the actuator and the safety switchgear
2. Remove particles of dust and soiling
3. Check cable entry and connections in a de-energised condition
Do not open the device when live.
Adequate measures must be taken to ensure protection
against tampering either to prevent tampering of the safety
guard, for instance by means of replacement actuators.
