- When the device is installed on a mobile frame and the actuator is installed on a
mobile door, ensure that the device cannot be damaged by simultaneous opening of
the frame and the door.
- After installation, check for correct operation of the auxiliary release (if present) and
the escape release button (if present).
- No work that can cause high-intensity electrostatic discharges (e.g. stripping or rubbing
plastic surfaces or other materials that can be electrostatically charged) may be carried
out in the vicinity of devices that are supplied with electrical energy, even if they are
switched off or not wired.
- Always attach the following instructions to the manual of the machine in which the
device is installed.
- These operating instructions must be kept available for consultation at any time and
for the whole period of use of the device.
6.2 Do not use in the following environments
Attention: Do not use in environments where dust and dirt may in any way
penetrate the head and deposit there. In particular where metal dust, concrete or
chemicals are spread.
- In environments where continual changes in temperature cause the formation of
condensation inside the device.
- In environments where the application causes the device to be subjected to strong
impacts or vibrations.
- In environments containing explosive or inflammable gases or dusts.
- In environments where ice can form on the device.
- In environments containing strongly aggressive chemicals, where the products used
coming into contact with the device may impair its physical or functional integrity.
- Prior to installation, the installer must always ensure that the device is suitable for

6.4 Maintenance and functional tests
Attention: Do not disassemble or try to repair the device. In case of any
malfunction or failure, replace the entire device.
Attention: In case of damages or wear it is necessary to change the whole
device including its actuator. Correct operation cannot be guaranteed when the device
is deformed or damaged.
- The device installer is responsible for establishing the sequence of functional tests
to which the device is to be subjected before the machine is started up and during
maintenance intervals.
- The sequence of the functional tests can vary depending on the machine complex-
ity and circuit diagram, therefore the functional test sequence detailed below is to be
considered as minimal and not exhaustive.
- Perform the following sequence of checks before the machine is commissioned and
at least once a year (or after a prolonged shutdown):
1) Lock the protection and start the machine. The guard must not open when the
actuator is pulled with a holding force of F
2) Try to start the machine while the guard is open. The machine must not start.
3) Check correct actuator to device alignment. If the actuator inlet is worn, replace the
entire device and actuator assembly.
4) When the auxiliary release (if present) is activated, the protection must open freely
and the machine must not start.
5) If the guard is closed but not locked, it must not be possible for the machine to start.
6) All external parts must be undamaged.
7) If the device is damaged, replace it completely.
8) The actuator must be securely locked to the door; make sure that none of the
machine operator's tools can be used to disconnect the actuator from the door.
9) If you have difficulty inserting the actuator in the switch, never apply oil or grease
to the switch head; instead, check the actuator alignment as described in paragraph
INSTALLATION INSTRUCTIONS. If it is still difficult to insert the actuator, replace the
entire device.
- The device has been created for applications in dangerous environments, therefore
it has a limited service life. Although still functioning, after 20 years from the date
of manufacture the device must be replaced completely. The date of manufacture is
placed next to the product code (see paragraph MARKINGS).
6.5 Wiring
Attention: Check that the supply voltage is correct before powering the device.
- Keep the charge within the values specified in the electrical operation categories.
- Only connect and disconnect the device when the power is off.
- Do not open the internal device cover under any circumstances.
- Discharge static electricity before handling the product by touching a metal mass
connected to earth. Any strong electrostatic discharge could damage the device.
- Always connect the protection fuse (or equivalent device) in series to the safety
electrical contacts.
- Always connect the protection fuse (or equivalent device) in series with the power
supply for each device (see paragraph ELECTRICAL DATA).
- Comply with the minimum and maximum sections of electrical conductors admitted
by terminals. The device contains two internal screw terminals for connecting the fol-
lowing wire types:
