2. احتياطات السلامة
يرجى دائمًا مراعاة احتياطات السلامة التالية لمنع الإصابة الشخصية أو تلف المعدات.
- المخاطر الكهربائية: Ensure power is disconnected before wiring or performing maintenance. Only qualified personnel should perform electrical work.
- التأريض: يجب تأريض محول التردد المتغير بشكل صحيح لمنع حدوث صدمة كهربائية.
- اتصال المحرك: The frequency converter must be directly connected to the motor. Control motor start/stop exclusively through the VFD to avoid damage.
- بيئة: Avoid operating the VFD in humid environments, or where water mist, water droplets, or metal objects may fall into the unit, as this can cause short circuits.
- External Resistor: If your motor operates under heavy load, consider using an external braking resistor.

5. الإعداد والأسلاك
Proper wiring is crucial for the safe and correct operation of the VFD. Refer to the wiring diagram below and follow these instructions carefully.

الشكل 5.1: Wiring diagram for connecting the VFD to a motor. This diagram illustrates the connections for single or three-phase 220V input (R, S, T terminals), grounding (PE terminal), three-phase 220V output to the motor (U, V, W terminals), and optional braking resistor connections (P+, BR terminals).
5.1 توصيل طاقة الإدخال
- Connect the AC 220V input power to the terminals labeled R, S، و T.
- For single-phase 220V input, connect the live wire to R and the neutral wire to T (أو L و N if labeled differently).
- For three-phase 220V input, connect each phase to R, S، و T على التوالى.
- Ensure proper circuit breakers are installed upstream for protection.
5.2 اتصال المحرك
- Connect the three-phase motor wires to the VFD output terminals labeled U, V، و W.
- Refer to your motor's wiring diagram to ensure it is configured for 220V operation (typically Delta connection for 220V).
- If the motor rotates in the wrong direction, you can swap any two of the U, V, W output wires, or adjust the rotation direction in the VFD's parameters.
- مهم: The motor must be directly connected to the VFD. Do not place any switches or contactors between the VFD and the motor.
5.3 التأريض
- Connect the ground wire from your power supply and the motor frame to the VFD's PE (Protective Earth) terminal.
- Ensure a solid, low-impedance ground connection.
5.4 Braking Resistor (Optional)
- For applications requiring rapid deceleration or operating with high inertia loads, an external braking resistor can be connected to terminals P+ و BR.
- Consult the VFD specifications and your application requirements to select an appropriate braking resistor.
