WARNING: Risk of electrical shock. Failure to observe may result in
personal injury, death, or equipment damage.
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).
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!
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 ).
WARNING: Connect external control and signal circuits with suitable cable
in accordance with the NEC, class 1. To prevent short-circuiting, lay the
cables such that they do not touch printed circuits on PCBs.
