Electrical Connections
WARNING: Risk of electrical shock. Failure to observe may result in
personal injury, death, or equipment damage.
Important Note When Using Residual Current Circuit Breakers
Local regulations in some geographic areas or industrial branches may
require residual current circuit breakers.
Then observe the following points:
Residual current circuit breakers are to be installed only between the
power supply and the melter.
Only residual current circuit breakers sensitive to pulsating current or
universal current (> 30 mA) may be used.
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!
CAUTION: Lay CAN bus cable with a bending radius > 60 mm (2.4 in).
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 connection cable must have a cross-section appropriate
for the maximum power consumption (refer to section Technical Data).
External Control/Signal Circuits
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.
