Installation & Maintenance Guide

Installation Requirements:

• Install inside an IP54 or well-ventilated electrical control panel to shield from excessive moisture and ambient dust.
• Maintain minimum side and vertical clearances around the VFD unit for proper airflow from the cooling fan.
• Ensure proper 3-phase grounding and use shielded motor cables to prevent electromagnetic interference (EMI).

Maintenance Tips:

• Periodically clear dust accumulation from heat sink fins and cooling fans using dry, low-pressure compressed air.
• Inspect terminal block screw tightness at regular intervals to prevent loose wiring connections due to machine vibration.
• Monitor operating alarms via the digital control panel to address parameter abnormalities early.

Safety Instructions:

• Always disconnect main power lines and wait at least 10 minutes for DC bus capacitors to fully discharge before opening internal terminals.
• Wiring and parameter configuration must be carried out by qualified electrical engineers or technicians.
