Note:
This section refers to equipment with voltages above 50 Volts.
Making contact with parts conducting voltages above 50 Volts could be
dangerous to personnel and cause an electrical shock. When operating
electrical equipment, it is unavoidable that some parts of the unit conduct
dangerous voltages.
High electrical voltage! Danger to life, severe
electrical shock and severe bodily injury!
⇒ Only those trained and qualified to work with or on
electrical equipment are permitted to operate,
DANGER
maintain or repair this equipment.
⇒ Follow general construction and safety regulations
when working on electrical installations.
⇒ Before switching on power the ground wire must be
permanently connected to all electrical units accor-
ding to the connection diagram.
⇒ Do not operate electrical equipment at any time if the
ground wire is not permanently connected, even for
brief measurements or tests.
⇒ Before working with electrical parts with voltage
potentials higher than 50 V, the equipment must be
disconnected from the mains voltage or power
supply.
⇒ The following should be observed with electrical
drives, power supplies, and filter components:
Wait five (5) minutes after switching off power to
allow capacitors to discharge before beginning work.
Measure the voltage on the capacitors before
beginning work to make sure that the equipment is
safe to touch.
⇒ Never touch the electrical connection points of a
component while power is turned on.
⇒ Install the covers and guards provided with the
equipment properly before switching the equipment
on. Prevent contact with live parts at any time.
⇒ A residual-current-operated protective device (r.c.d.)
must not be used on an electric drive! Indirect
contact must be prevented by other means, for
example, by an overcurrent protective device.
⇒ Equipment that is built into machines must be
secured against direct contact. Use appropriate
housings, for example a control cabinet.
European
section 5.3.2.3.
U.S.A: See National Electrical Codes (NEC), National
Electrical Manufacturers Association (NEMA) and local
building codes. The user of this equipment must observe
the above noted instructions at all times.
