DANGER
DANGER
High electrical voltage! Danger to life, electric shock and severe
bodily injury!
•
Only those trained and qualified to work with or on electrical equipment are
permitted to operate, maintain and repair this equipment.
•
Follow general construction and safety regulations when working on electri-
cal power installations.
•
Before switching on the device, the equipment grounding conductor must
have been permanently connected to all electrical equipment in accordance
with the connection diagram.
•
Do not operate electrical equipment at any time, even for brief measure-
ments or tests, if the equipment grounding conductor is not permanently
connected to the mounting points of the components provided for this pur-
pose.
•
Before working with electrical parts with voltage potentials higher than 50 V,
the device must be disconnected from the mains voltage or power supply
unit. Provide a safeguard to prevent reconnection.
•
For electrical drive and filter components, observe the following:
Wait 30 minutes after switching off power to allow capacitors to dis-
charge before beginning to work. Measure the electrical voltage on the ca-
pacitors before beginning to 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 device on. Before switching the equipment on, cover and safe-
guard live parts safely to prevent contact with those parts.
•
A residual-current-operated circuit-breaker or r.c.d. cannot be used for elec-
tric drives! Indirect contact must be prevented by other means, for example,
by an overcurrent protective device according to the relevant standards.
•
Secure built-in devices from direct touching of electrical parts by providing
an external housing, for example a control cabinet.
For electrical drive and filter components with voltages of more than
50 volts, observe the following additional safety instructions.
High housing voltage and high leakage current! Risk of death or
bodily injury by electric shock!
•
Before switching on, the housings of all electrical equipment and motors
must be connected or grounded with the equipment grounding conductor to
the grounding points. This is also applicable before short tests.
•
The equipment grounding conductor of the electrical equipment and the de-
vices must be non-detachably and permanently connected to the power
supply unit at all times. The leakage current is greater than 3.5 mA.
•
Over the total length, use copper wire of a cross section of a minimum of 10
mm² for this equipment grounding connection!
•
Before commissioning, also in trial runs, always attach the equipment
grounding conductor or connect to the ground wire. Otherwise, high voltag-
es may occur at the housing causing electric
