Safety instructions for electric drives and controls
Instructions with regard to specific dangers
Protection against contact with electrical parts and housings
Health hazard for persons with heart pacemakers, metal implants and
hearing aids in proximity to electric drive systems!
Risk of burns by hot housing surfaces!
Risk of injury by improper handling! Injury by crushing, shearing, cutting,
Risk of injury by improper handling of batteries!
Risk of injury by improper handling of pressurized lines!
This section concerns components of the electric drive and con‐
trol system with voltages of more than 50 volts.
Contact with parts conducting voltages above 50 volts can cause personal
danger and electric shock. When operating components of the electric drive
and control system, it is unavoidable that some parts of these components
conduct dangerous voltage.
High electrical voltage! Danger to life, risk of injury by electric shock or seri‐
ous 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
equipment 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 supply unit. Secure the electric component from reconnec‐
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 elec‐
trical voltage of live parts before beginning to work to make sure that the
equipment is safe to touch.
Install the covers and guards provided for this purpose before switching
Never touch any electrical connection points of the components while
power is turned on.
Do not remove or plug in connectors when the component has been
Under specific conditions, electric drive systems can be operated at
mains protected by residual-current-operated circuit-breakers sensitive
to universal current (RCDs/RCMs).
