For your personal safety and to prevent material damage when working on the machine,
always observe the safety instructions and the following five safety rules. Apply the five
safety rules in the order stated before starting work at the machine.
Five safety rules
1. Disconnect the system.
2. Protect against reconnection.
3. Make sure that the equipment is at zero voltage
4. Ground and short-circuit
5. Cover or enclose adjacent components that are still live.
When work has been completed, remove these measures in reverse order.

Thermal hazard
The surface temperature of the motors can exceed 100°C.
Do not touch hot surfaces!
Temperature-sensitive components (electric cables, electronic components) must not be
placed on hot surfaces. If the motors overheat, this can destroy the windings/bearings and
the permanent magnet may become demagnetized
Only operate the motors in conjunction with effective temperature control.
