2.6 Safety classification of the guard locking function
If the device is used as an interlock for personal safety, a safety
classification of the guard locking function is required.
When classifying the guard locking function, a distinction must be
made between monitoring of the interlocking function and control of the
release function.
The following classification of the release function is based on the prin-
ciple of isolating the supply of power to the solenoid.
The safety classification for the release function only applies
to devices with monitored interlock function, in power to
unlock version and with solenoid supply from 24 VDC (AUX)
(see ordering code).
By reliably isolating the power externally, it can be assumed that no
errors can occur with regard to actuation of the release function. In that
case, the device does not contribute towards the failure probability of
the release function.
The level of safety of the release function relies, therefore, exclusively
on reliable external deactivation of the power.

Fault exclusion with regard to wiring routing must
be observed.
If for a certain application the power to unlock version of
a solenoid interlock cannot be used, for this exception
an interlock with power to lock can be used if additional
safety measure need to be realised that have an
equivalent safety level.
3. Mounting
3.1 General mounting instructions
The installation may only be carried out by authorised
personnel.
For fitting the AZM 200 AS solenoid interlock, two mounting holes for
M6 screws with washers (washers included in delivery) are provided.
The solenoid interlock must not be used as an end stop. Any mounting
position. The mounting position however must be chosen so that the
ingress of dirt and soiling in the used opening is avoided. The unused
actuator opening must be sealed by means of the dust-proof flap
(included in delivery).
Minimum distance between two devices: 100 mm
Fitting of the actuator
Refer to the mounting instructions manual for the corresponding
actuator.
The actuator must be permanently fitted to the safety guards
and protected against displacement by suitable measures
(tamperproof screws, gluing, drilling of the screw heads).
Please observe the relevant requirements of the standards
ISO 12100, ISO 14119 and ISO 14120.
