Risk of explosion due to static charging
If you clean the motor, plastic components may become statically charged and ignite a
potentially explosive atmosphere. An explosion can occur. This can result in death, serious
injury or material damage.
• When cleaning ensure that there is absolutely no explosive atmosphere present.
• Clean the plastic parts and components so that absolutely no static charging occurs
• Do not use compressed air for cleaning.
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.
• Take the machine out of operation.
• Switch off the machine and ensure that it is in a no-voltage condition. Carefully comply
with the "5 safety rules" (Page 11).
• Only open the terminal box when the motor is stationary and in a no voltage condition.
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 result in death, serious injury or material
damage.
• Before carrying out any repair work on the machine, take it out of operation, and carefully
lock it out so that it cannot be switched on again.
• Only remove the covers when the rotating parts have come to a complete standstill.
Risk of burn injuries due to hot surfaces
In operation, the temperature of individual machine parts can increase - and only decrease
slowly after switching off. You can burn yourself if you touch hot surfaces.
• Allow the machine to cool before starting any maintenance and service work on the
machine.
• Check the temperature of parts before touching them. If required, wear suitable protective
equipment.
Damage if the machine is not maintained
The machine can be damaged if it is not appropriately maintained. This can cause faults
which can result in eventual or immediate death, serious injury or material damage.
• Maintain the machine at the specified maintenance intervals.
