Protection Against Contact with Electrical Parts

LSA Control S.L. (+34) 960 62 43 01
Safety Instructions for Electric Drives and Controls
This section refers to equipment and drive components with
voltages above 50 Volts.
Touching live parts with voltages of 50 Volts and more with bare hands or
conductive tools or touching ungrounded housings can be dangerous and
cause electric shock. In order to operate electrical equipment, certain
parts must unavoidably have dangerous voltages applied to them.
High electrical voltage! Danger to life, severe
bodily harm by electric shock!
⇒ Only those trained and qualified to work with or on
electrical equipment are permitted to operate, maintain
or repair this equipment.
⇒ Follow general construction and safety regulations when
working on high voltage installations.
⇒ Before switching on power the ground wire must be
permanently connected to all electrical units according
to the connection diagram.
⇒ Do not operate electrical equipment at any time, even
for brief measurements or tests, if the ground wire is not
permanently connected to the points of the components
provided for this purpose.
⇒ Before working with electrical parts with voltage higher
than 50 V, the equipment must be disconnected from
the mains voltage or power supply. Make sure the
equipment cannot be switched on again unintended.
⇒ The following should be observed with electrical drive
and filter components:
⇒ Wait five (5) minutes after switching off power to allow
capacitors to discharge before beginning to work.
Measure the voltage on the capacitors before beginning
to work to make sure that the equipment is safe to
⇒ 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 (RCD)
must not be used on electric drives! Indirect contact
must be prevented by other means, for example, by an
overcurrent protective device.
⇒ Electrical components with exposed live parts and
uncovered high voltage terminals must be installed in a
protective housing, for example, in a control cabinet.
