NOTICE!
PLC damage due to wrong enclosures
Due to their construction (degree of protection IP 20 according to EN 60529)
and their connection technology, the devices are suitable only for operation in
enclosed switchgear cabinets.
To protect PLCs against:
● unauthorized access,
● dusting and pollution,
● moisture and wetness and
● mechanical damage,
switchgear cabinet IP54 for common dry factory floor environment is suitable.
Maintain spacing from:
● enclosure walls
● wireways
● adjacent equipment
Allow a minimum of 20 mm clearance on all sides. This provides ventilation and electrical isola-
tion.
It is recommended to mount the modules on an earthed mounting plate, or an earthed DIN rail,
independent of the mounting location.
