Safety information
Warning
Please observe the chapter entitled "Safety information" in these Operating
Instructions precisely and ensure that only persons who have the necessary
specialist know-how are entrusted to carry out work on power installations.
All covers which are designed to prevent active or rotating parts from being
touched, or which are necessary to ensure correct air guidance and thus more
effective cooling, must not be opened during operation.
An appropriately configured control system and speed monitoring equipment must
be used to ensure that speeds higher than the permissible speeds stated on the
rating plate do not arise.
Energizing
Always refer to the respective manual of the frequency converter when energizing.
After starting the motor, observe it for a while to see if it is running smoothly and
check the monitoring devices.
Operation
Monitor operation and the monitoring devices regularly and record the values you
read off.
Warning
All deviations from normal operation, such as higher power consumption, higher
temperatures and vibration levels, unusual noises and odours and tripped
monitoring devices, are indications that the motor is no longer functioning correctly.
In this case, the maintenance technician must be immediately notified in order to
prevent disturbances that could either directly or indirectly lead to severe personal
injury or substantial material damage.
