Electrical Connections
WARNING: Risk of electrical shock. Failure to observe may result in
personal injury, death, or equipment damage.
General Notes
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%.
Observe when Using Residual Current Circuit Breakers
Local regulations in some industrial branches require residual current circuit
breakers.
Then observe the following points:
S Residual current circuit breakers are to be installed only between the
power supply and the melter.
S Use only residual current circuit breakers sensitive to pulsating current
or universal current (> 30 mA).
Laying Cable
WARNING: Use only temperature resistant cable in warm areas of the
equipment. Ensure that cables do not touch rotating and/or hot melter
components. Do not pinch cables and check regularly for damage. Replace
damaged cables immediately!
Operating Voltage
WARNING: Operate only at the operating voltage shown on the ID plate.
NOTE: Permitted deviation from the rated line voltage is 10%.
NOTE: The power cable cross-section must comply with the maximum
power consumption (refer to section Technical Data ).
