Safety instructions during operation
All terminal boxes must be closed
Terminal boxes contain live electrical parts. Death, serious injury or material damage can
result if terminal box covers are removed.
When the machine is in operation, the terminal boxes must remain closed at all times.
Terminal boxes may be opened only when the machine is stopped and de-energized.
Do not remove covers when the motor is running
Rotating or live parts are dangerous. Death, serious injury or material damage can result if
the required covers are removed.
Any covers that prevent live electrical or rotating parts from being touched, or that ensure
compliance with a particular degree of protection or are required for ensuring proper air flows,
and hence effective cooling, must not be opened during operation.
Faults in operation
Deviations from normal operation such as increased power consumption, temperatures or
vibrations, unusual noises or odors, tripping of monitoring devices, etc., indicate that the
machine is not functioning properly. This can cause faults which can result in eventual or
immediate death, serious injury or material damage.
● Immediately inform the maintenance personnel.
