(*) The 4-20 mA pressure probes are connected by attaching white to Ux and black to +Vdc, green is not used

Caution: if the PEC version inverters (with class B software structure) are not used, the thermal protection devices for overload and high pressure must

act directly on the compressor actuator, and must therefore be wired in series with the compressor contactor coil control. For the types of cable to be used,

see the power+ manual ( +0300094EN).
