Operation
5.1 Safety instruction
Instructions relevant for safety
Warning
All covers which are designed to prevent live or rotating parts from being touched,
or which are necessary to ensure correct air guidance and thus effective cooling,
must not be opened during operation.
All deviations from normal operation (higher power consumption, temperature or
vibration level, unusual noises or odours, tripped monitoring devices, etc.) 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. If in doubt, power-down the motor immediately in
conformance with the system-specific safety requirements.
Note
Operating the motor at the intrinsic installation frequency can cause damage to the
motor and foundation and is not permissible.
Danger
The control system must be interlocked in such a way that the armature circuit can
only be energized when the excitation is active. If the excitation fails, the armature
circuit must be disconnected immediately.
Caution
Temperatures of up to or even over 100 °C can occur on the housing parts. Any
contact must be avoided.
