Operating conditions for shaft heights 180 and 225
Carefully take into account the following operating conditions when operating motors in a Zone
22 hazardous area:
• Provide speci󹪝c operating instructions for the motors for when they are used in hazardous
areas (see link and documentation in the Intranet/Internet).
• Zone 22 (option M39):
– Marking: II 3D Ex tc IIIB T155 °C Dc IP55 -15°C ≤ Ta ≤ +40°C
– Device group II, category 3D
– Protection a󹪜orded by the enclosure, tc
– Maximum surface temperature 155°C (according to EN 60079-0: 2012 general
requirements)
– Use in ambient temperatures -15 °C up to +40 °C at installation altitudes up to 1000m
• Evaluate the temperature sensor embedded in the motor winding.
• Safely and reliably shut down explosion protected separately driven fans when an overload
condition occurs. PTC sensors are integrated as standard for overload protection, which must
be evaluated according to EN 60079-14.
• Attach the twist protection provided for the signal connector in compliance with regulations.
• Use Ex-certi󹪝ed cable glands for the power connection. Close and seal unused threads using
Ex-certi󹪝ed screw plugs.
• The thermal stability of the connecting cables must be at least 80°C. Plastic-insulated,
󹪞exible cables must have the same durability as heavy-duty, rubber-insulated cables.
SIEMENS MOTION-CONNECT power and signal cables meet these requirements.
• The motors have a ground connection at the bearing shield/enclosure. Additionally ground
the motors at this connection point.
• Belt drives are only permissible if buildup of a static charge is ruled out in the machinery.
• Keep the motors free of dust layers >5mm.
