(*) The 4-20 mA pressure probes are connected as follows: white to Ux and black to +Vdc, green not used
(**) 230 Vac SSR output, maximum switchable power 15VA
Important: Class A software: the safety devices providing overload and high pressure protection must control the compressor directly, and consequently need
to be wired in series with compressor contactor control signal. For the type of cable to use, refer to power+ manual (cod. +0300048IT).
