Shield/Schermo
For thermocouples K, S, R, J, T, E, N, B.
• 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

• For the three-wire connection use wires with the same section
• For the two-wire connection short-circuit terminals 1 and 3
• When shielded cable is used, it should be grounded at one
side only
