and Controls
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 elec‐
trical power installations.
●
Before switching on the device, the equipment grounding conductor must
have been permanently connected to all electrical equipment in accord‐
ance 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
purpose.
●
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 discharge
before beginning to work. Measure the voltage in the capacitors before
beginning work to preclude the risk of danger if the device is touched.
●
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
safeguard live parts safely to prevent contact with those parts.
●
A residual-current-operated circuit-breaker or r.c.d. cannot be used for
electric 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.
European countries: in accordance with EN 50178/ 1998, Section 5.3.2.3.
USA: See National Electric Code (NEC), National Electric Manufacturers As‐
sociation (NEMA) and any regional building codes. The user must comply with
all the above points at all times.
For electrical drive and filter components, observe the following:
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
devices 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 mm
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 vol‐
tages may occur at the housing causing electric shock.
