Electrical wirings
Although this controller was designed to resist electro-
magnetic interferences in industrial environments, please
observe following safety guidelines:
• Separate the control line from the power wires.
• Avoid proximity of remote control switches, electroma-
gnetic contactors, powerful engines and in all instances
use specific filters.
• Avoid proximity of power groups, especially those with
phase control

Shield/Schermo
For thermocouples K, S, R, J.
• Comply with polarity
• For possible extensions, use
compensated cable and terminals
suitable for the thermocouples
used(compensated)
• When shielded cable is used, it should
be grounded at one side only
