European countries: see Directive 89/336/EC (EMC Directive).
US.: Refer to the National Electrical Code (NEC), National Electrical
Manufacturers Association (NEMA), and local building codes. The user of
this equipment must observe the above noted items at all times.
•
Technical data, connections and operational conditions are specified in
the product documentation and must be followed at all times.
1.5 Protection against contact with electrical parts
Note: This section refers to equipment with voltages above 50 Volts.
Making contact with parts at 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 danger-
ous voltages.
DANGER
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, main-
tain or repair this equipment.
⇒
Follow general construction and safety regulations
when working on electrical installations.
⇒
Before powering-up, the productive conductor must
be permanently connected to all electrical units ac-
cording to the connection diagram.
⇒
Do not operate electrical equipment at any time if the
protective conductor is not permanently connected,
even for brief measurements or tests.
⇒
Before working with electrical parts with voltage po-
tentials higher than 50 V, the equipment must be
disconnected from the line supply or power supply.
⇒
The following should be observed with electrical
drives, power supplies, and filter components:
Wait five (30) minutes after switching off power to
allow capacitors to discharge before beginning work.
Measure the voltage at the capacitors before begin-
ning 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 con-
tact may be prevented by other means, for example,
by an overcurrent protective device.
⇒
Equipment that is built into machines must be se-
