Safety Instructions for Electric Drives and Controls
High electrical voltage! Danger to life, risk of injury by electric shock or serious
injury!
Only qualified persons are allowed to operate, maintain and/or repair the
●
components of the electric drive and control system.
Follow the general installation and safety regulations when working on power
●
installations.
Before switching on, the equipment grounding conductor must have been
●
permanently connected to all electric components in accordance with the
connection diagram.
Even for brief measurements or tests, operation is only allowed if the equip-
●
ment grounding conductor has been permanently connected to the points of
the components provided for this purpose.
Before accessing electrical parts with voltage potentials higher than 50 V, you
●
must disconnect electric components from the mains or from the power sup-
ply unit. Secure the electric component from reconnection.
With electric components, observe the following aspects:
●
Always wait 30 minutes after switching off power to allow live capacitors to
discharge before accessing an electric component. Measure the electrical
voltage of live parts before beginning to work to make sure that the equip-
ment is safe to touch.
Install the covers and guards provided for this purpose before switching on.
●
Never touch electrical connection points of the components while power is
●
turned on.
Do not remove or plug in connectors when the component has been pow-
●
ered.
Under specific conditions, electric drive systems can be operated at mains
●
protected by residual-current-operated circuit-breakers sensitive to universal
current (RCDs/RCMs).
Secure built-in devices from penetrating foreign objects and water, as well as
●
from direct contact, by providing an external housing, for example a control
cabinet.
High housing voltage and high leakage current! Danger to life, risk of injury by
electric shock!
Before switching on and before commissioning, ground or connect the com-
●
ponents of the electric drive and control system to the equipment grounding
conductor at the grounding points.
Connect the equipment grounding conductor of the components of the elec-
●
tric drive and control system permanently to the main power supply at all
times. The leakage current is greater than 3.5 mA.
