8.1.1 Safety instructions in operation - parts that are not covered, and that are
under voltage (live parts)
Danger as a result of stationary parts under voltage (live parts)
Live parts represent a hazard. Touch protection against active (live) parts is no longer
guaranteed if covers are removed. The minimum air and creepage distances may be fallen below
(violated) when coming close to active parts. Touching or coming close can result in death,
serious injury or material damage.
• Carefully ensure that all of the covers are closed while operational.
• First switch off and disconnect the machine if you must remove covers. Carefully comply with
the "5 safety rules" (Page 17).
• In operation, the terminal box must always be kept closed. It is only permissible to open the
terminal box when the motor is stationary and in a no voltage condition.
8.1.2

Safety instructions in operation - uncovered, rotating parts

Risk of injury due to rotating parts
Rotating parts are dangerous. Touch protection against rotating parts is no longer guaranteed
if covers are removed. Touching rotating parts can cause sparking with subsequent ignition of
an explosive atmosphere resulting in death, serious injury or material damage.
• Carefully ensure that all of the covers are closed while operational.
• First switch off and disconnect the machine if you must remove covers. Carefully comply with
the "5 safety rules (Page 17)".
• Only remove the covers when the rotating parts have come to a complete standstill.
