6. Installation & Maintenance
Installation
Usually installed in industrial control cabinets that meet NEMA 1 or NEMA 4 standards. Before installation, ensure sufficient heat dissipation space and ventilation.
Wiring
Requires professional electrical knowledge. The high-voltage input side and low-voltage output side must be strictly separated, and grounding and electrical safety specifications must be followed.
Commissioning
Before the first start-up, basic parameters need to be set, such as motor type, motor power, voltage, and rotor resistance.
Maintenance
Regularly inspect cooling fans, fastening bolts, and terminal blocks; monitor fault codes and replace damaged power semiconductor modules in a timely manner.

________________________________________________【Delivery Time】1. Express Shipping (DHL, UPS, FedEx, EMS):3-10 working days is a good rule of thumb. These services prioritize speed and often offer features like next-day or guaranteed delivery by a certain date (for an additional fee).2. Air Mail (China Post, Hong Kong Post):7-35 working days, depending on the destination country. This is a more budget-friendly option, but it takes longer because it has lower priority for shipment.【Important Notes】
