Safety instructions 2
Residual hazards
M o tor protection
• Installed therm al detectors are no full protection for the machine.
- If required, lim it the m axim um current, param eterise the controller such th at it
w ill be switched off after some seconds of operation w ith I > In, especially if
there is the danger o f blocking.
- Installed overload protection does not prevent an overload under any
conditions.
• Installed brakes are no fail-safe brakes.
- The torque can be reduced due to disruptive factors that cannot be influenced,
e.g. by ingressing oil due to a defect shaft sealing ring on the A side.
• Fuses are no m otor protection.
- Use current-dependent m otor protection switches at average operating
frequency.
- Use installed therm al detectors at high operating frequency.
• Too high torques cause a fraction of the m otor shaft.
- The m axim um torques according to catalogue must not be exceeded.
• Lateral forces from the m otor shaft m ay occur.
-A lig n shafts o f m otor and driving m achine exactly to each other.
• If deviations from normal operation occur, e.g. increased tem perature, noise,
vibration, determine the cause and, if necessary, contact the manufacturer. If in
doubt, switch o ff the m otor.
Fire protection
• Fire hazard
- Prevent contact w ith flam m able substances.
