Installing electrical connections
Electrically live parts cause electric shocks if touched, leading to
serious injuries and even death.
Observe the five safety rules of electrical engineering before starting
electrical installation work:
- Disconnect.
- Secure against being switched on again.
- Check that there is no voltage.
- Ground and short-circuit.
- Cover neighboring and electrified parts.
Before switching the voltage back on, check that all electrified parts are
equipped with suitable and undamaged contact protection.
Check that protective caps are on the plugs. If protective caps are
missing, check the plugs for damage and soiling.
Electric operation during moisture may result in electric shocks and
can cause serious injuries and even death.
Execute the electric assembly only in dry areas.
Excessively high contact voltages may cause electrical shock, which
may lead to serious injuries and even death.
Avoid excessively high contact voltages (e.g. in the event of damage to
the insulation) by providing all exposed and electrically live parts with a
protective earth.
Connect the terminal provided at the motor (e.g. direct PE conductor,
grounding terminal, ground pin in the motor connector) with the relevant
counterpart in the system ground.
For protective earth, use a conductor cross-section that is at least equal
to the motor's power supply cable, unless otherwise provided in
applicable regulation.
Not connecting the earth conductor may lead to electrostatic
discharges which can lead to explosions. Explosions can cause
serious injuries and even death.
Ensure that the earth conductor is properly connected.
