Installation & Maintenance Guide

Installation Requirements:

1. Mount the drive vertically inside an IP54-rated control panel to allow natural air movement and fan ventilation.
2. Maintain at least 10 cm (4 inches) of vertical clearance above and below the amplifier for adequate thermal airflow.
3. Establish a solid protective earth (PE) ground wire connection to the main panel ground point to prevent noise and electrical shock.
4. Route signal and pulse input wiring away from high-voltage AC motor power cables to avoid electromagnetic interference.

Maintenance Tips:

1. Periodically clear dust and debris from cooling fan airways and heatsinks using dry compressed air.
2. Regularly check terminal block screw connections to ensure power leads remain securely tightened.
3. Inspect cabinet ventilation fans and air filter pads to ensure ambient panel temperatures stay below 55°C.

Safety Instructions:

1. Turn off all main AC power sources and wait at least 10–15 minutes before touching terminals or wiring.
2. Confirm the internal charge light is completely extinguished before removing safety covers.
3. Only qualified electrical or automation personnel should perform installation, parameter setup, and maintenance work.
