WARNING!
Ignoring any of given instructions or maintenance of the apparatus may jeopardize the safety and thus prevents the use of the machine.
4.2 Cooling
Check that the motor has sufcient airow. Ensure that no nearby objects or direct sunshine radiate additional heat to the motor.
For ange mounted motors (e.g. B5, B35, V1), make sure that the construction allows sufcient air ow on the outer surface of the ange.
4.3 Safety considerations
The machine is intended for installation and use by qualied personnel, familiar with health and safety requirements and national legislation.
Safety equipment necessary for the prevention of accidents at the installation and operating site must be provided in accordance with local regulations.
WARNING!
Do not carry out work on motor, connection cables or accessories such as frequency converters, starters, brakes, thermistor cables or heating elements when
voltage is applied.
Points to observe
1. Do not step on the motor.
2. The temperature of the outer casing of the motor may be too hot to touch during normal operation and especially after shut-down.
3. Some special motor applications require special instructions (e.g. using frequency converter supplies).
4. Be aware of rotating parts of the motor.
5. Do not open terminal boxes while energized., for singhle phase motors pay attention at the capacitor descharge even when the line supply is disconnected.
5. MAINTENANCE
WARNING!
Voltage may be connected at standstill inside the terminal box for heating elements or direct winding heating.
WARNING!
The capacitor in single-phase motors can retain a charge that appears across the motor terminals, even when the motor has reached standstill.
