Need help?
Do you have a question about the Versati IV GRS-CQ4.0PdG/NhH3-E and is the answer not in the manual?
Questions and answers
Please give me information how to connet the cables. There are many ways to connect, but what is the right connection.
To connect the cables for the Gree GRS-CQ4.0PdG/NhH3-E:
1. Use power supply wire and earth wire with a minimum sectional area of 1.5 mm².
2. Ensure power cables are protected with rubber or plastic to prevent damage from metal edges.
3. Fix power cables securely near the electric cabinet to protect the power terminal from external force.
4. Ground the power cable reliably.
5. For 2-way valve wiring:
- For a Normally Open valve: connect to wire (OFF) and wire (N).
- For a Normally Closed valve: connect to wire (ON) and wire (N).
- (OFF) and (ON) are line signals from the PCB; (N) is the neutral signal.
Power supply requirement: 400V, 3-phase, 50Hz. Use a 16A leakage switch.
