Chapter 2.4.4 “EMC-conforming assembly and
construction” on page 918.
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 galvanic
isolation.
It is recommended to mount the modules on an grounded mounting plate, or an grounded DIN
rail, independent of the mounting location.
