5. Opsætning og installation
Proper installation is crucial for the motor's performance and longevity.
5.1 Montering
- The motor features a B3 frame, indicating foot mounting. Ensure the mounting surface is flat, rigid, and capable of supporting the motor's weight and operational forces.
- Use appropriate bolts and washers to secure the motor firmly to the base. Check for proper alignment with the driven equipment to prevent excessive vibration and premature bearing wear.
5.2 Elektrisk tilslutning
Alt elektrisk arbejde skal udføres af en autoriseret elektriker.
- Strømforsyning: Connect the motor to a 220-240 V AC, 50 Hz single-phase power supply. Ensure the circuit has adequate current capacity (9.85 A nominal) and is protected by a suitable circuit breaker or fuse.
- Jording: Properly ground the motor frame to prevent electric shock.
- Rotation Direction (CW/CCW): The motor supports reversible rotation. Refer to the wiring diagram provided on the motor's terminal box cover for instructions on how to change the rotation direction (Clockwise/Counter-Clockwise). Typically, this involves reconfiguring the capacitor connections or main winding leads.
- Kabelforskruninger: Use appropriate cable glands to ensure a secure and sealed entry for power cables into the terminal box, maintaining the motor's ingress protection rating.
6. Betjeningsvejledning
Follow these guidelines for safe and efficient operation of your motor.
6.1 Kontrol før brug
