5. Configuració i instal·lació
5.1 Precaucions de seguretat
- Assegureu-vos que l'alimentació estigui desconnectada abans de qualsevol instal·lació o manteniment.
- La instal·lació només l'ha de fer personal qualificat.
- Utilitzeu equips de protecció individual (EPI) adequats.
- Comproveu que el volum de subministramenttage i la freqüència coincideixen amb les especificacions del motor.
- Ensure proper grounding of the motor.
5.2 Muntatge
The motor is designed for horizontal foot mounting (B3). Use the pre-drilled holes on the fixed base for secure installation. Ensure the mounting surface is stable, level, and capable of supporting the motor's weight (15kg) and operational forces.
Refer to the dimensions in Section 4.1 for precise mounting hole spacing.
5.3 Connexions elèctriques
The motor requires a 3-phase power supply. The default connection for nominal output ≤4hp (3kW) is a Star (Y) connection for 380V. For 220V operation, you may need to change to a Delta (Δ) connection. Consult a qualified electrician for wiring.
Wiring must comply with local electrical codes and regulations.
Figura 4: Esquemes de cablejat
This image provides standard wiring diagrams for three-phase squirrel-cage induction motors, including Star (Y), Delta (Δ), and Star-Delta (Y-Δ) connections, as well as configurations for two-speed motors.
- Star (Y) Connection: Typically used for higher voltage (e.g., 380V). Connect terminals W2, U2, V2 together, and connect L1, L2, L3 to U1, V1, W1 respectively.
- Delta (Δ) Connection: Typically used for lower voltage (e.g., 220V). Connect U1-W2, V1-U2, W1-V2, then connect L1, L2, L3 to these respective junctions.
- Posada a terra: Always connect the motor's ground terminal to a reliable earth ground.
