Control circuitry wiring must be separated terminated and away from the primary power
circuitry and other high-voltage or large-current power lines to avoid noise interference.
• To reduce the noise interference and avoid possible operational problems, shielded twisted
pair cable should be used to wire the control circuitry. Please refer to following diagram.
Connect the shielding wire onto the grounding terminal. Only connect one end of the shield.
Wiring distance must be under 50m.

The grounding terminal of the inverter must be correctly grounded in compliance with 200V
class type three grounding.
• Grounding wire should be wired in accordance to electrical equipment (AWG) with the
length of the grounding wire as short as possible.
• The grounding wire of the inverter must not be grounded together with other large current loads
(such as soldering machines or large current motors). They should be grounded separately.
• Grounding circuitry must not be formed when grounding several inverters together.
(D)
Wire specification, apply appropriate wire with correct diameter for primary power
circuitry and control circuitry in accordance with electricity regulations.
