PLC enclosure
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.
