such as communication via Local Bus, recording manual operations, certain measurements and the
datalogger must be activated.
The auxiliary supply can be provided by modules from the Ekip Supply range or by direct connection to the
terminal box.
Direct connection must guarantee the following operating conditions:

IMPORTANT: if connection is direct, the power supply must be galvanically insulated
and provide the insulation characteristics established by standard IEC 60950 (UL
1950) or equivalent.
