Safety Instructions for Electric Drives and Controls
To be observed with electrical drive and filter components:
High electrical voltage on the housing!
High leakage current! Danger to life, danger of
injury by electric shock!
⇒ Connect the electrical equipment, the housings of all
DANGER
electrical units and motors permanently with the safety
conductor at the ground points before power is
switched on. Look at the connection diagram. This is
even necessary for brief tests.
⇒ Connect the safety conductor of the electrical
equipment always permanently and firmly to the
supply mains. Leakage current exceeds 3.5 mA in
normal operation.
⇒ Use a copper conductor with at least 10 mm² cross
section over its entire course for this safety conductor
connection! The cross section must not be smaller
than the cross section of a phase of the mains supply
wire.
⇒ Prior to startups, even for brief tests, always connect
the protective conductor or connect with ground wire.
Otherwise, high voltages can occur on the housing
that lead to electric shock.
