General Information
S To conform with a European standard regarding electro-magnetic
compatibility (EMC), only shielded cable may be connected. The cable
must be connected to ground in compliance with the standard regarding
electromagnetic compatibility.
S Inductive loads (e.g. solenoid valves) connected to the melter must be
equipped with a protective device (e.g. recovery diode) that disables the
inductive voltage generated when an inductive load is switched off.
S The permitted voltage deviation is 10%.
S In Field bus mode (option Field bus communication) the unit can not be
controlled via the interface.
