General Information
All PEP products are intended for use in industrial climates where extreme environments exist. Dirt, temperature extremes, varying humidity levels, vibration, noise, shock and electromagnetic signals must all be considered. Only when certain precautions have been followed can PEP guarantee the performance of the product stated in the data sheet.
In most cases, controllers are situated in close vicinity to electromechanical devices like relays, transformers, motor controllers and
•Earth protect the controller fixing
•Use screened/shielded cable connections
•Place cables according to relevant standards
•Observe the use of the correct cable diameter and type
•For unused module sockets, install a blank
•Leave enough room between a ‘hot body’ and the controller for air to circulate freely
•Place the controller as far away as possible from ‘noisy’ components
•Separate digital and analog cabling
•Only replace/insert modules in the carrier unit with the power OFF
•Handle the controller components with care; Modules containing highly integrated CMOS components are very sensitive to static discharges
•Try to separate analog modules from their digital cousins.
