ATTENTION
: according to safety standards, the device must be properly positioned and protected from any contact with electrical parts. The device must be fastened in such
a way that it cannot be removed without the use of tools. Disconnect the main safety switch of the installation before proceeding to any maintenance. Disconnect the power
supply of the device before proceeding to any maintenance. Do not place the device near heat sources, equipment containing strong magnets, in areas affected by direct
sunlight or rain. Prevent electrostatic discharges and sharp objects from been inserted to the device. Separate signal cables from power supply cables to prevent electromagnetic
disorders. Signal cables must never be in the same pipe with the power supply cables.
ATTENTION
: Read carefully the technical specifications and make sure that the working
conditions are appropriate. According to safety standards, the device must be fastened in such a way that it cannot be removed without the use of tools.
Dimensions are in mm. The device is mounted on panel hole with cut 29x71mm and restrained with plastic side brackets.
