Safety Instructions for Electric Drives and Controls
– Measure the voltage on the capacitors 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 safeguard live parts
safely to prevent contact with those parts.
● A residual-current-operated circuit-breaker cannot be used for electric drives! Indi‐
rect contact must be prevented by other means, for example, by an over current pro‐
tective device according to the relevant standards.
● Secure built-in devices from direct touching of electrical parts by providing an exter‐
nal housing. For example: a control cabinet.
Always observe the above requirements, in accordance with relevant inter‐
national standards.
With electrical drive and filter components, observe the following:
DANGER
● 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 units must
be non-detachably and permanently connected to the power supply unit at all times.
● Over the total length, use copper wire of a cross section of a minimum of 10 mm
this equipment grounding connection!
● Before start-up, also in trial runs, always attach the equipment grounding conductor
or connect with the ground wire. Otherwise, high voltages may occur at the housing
causing electric shock.
