- Page 9 ≥500mm ≥500mm For proper air circula�on to dissipate heat, allow a clearance of approx. 50cm to the side and approx. 50cm above and below the unit. And 100cm to the front. Moun�ng the inverter Remember that this inverter is heavy! Please be careful when li�ing out from the package. Choose the recommend drill head(as shown in below pic) to drill 4 holes on the wall, 82-90mm deep.
- Page 10 3.3 Ba�ery connec�on For safe opera�on and compliance, a separate DC over-current protector or disconnect device is required between the ba�ery and the inverter. In some applica�ons, switching devices may not be required but over-current protectors are s�ll required. Refer to the typical amperage in the table below for the required fuse or circuit breaker size.
- Page 11 All wiring must be performed by a professional person. Connec�ng the ba�ery with a suitable cable is important for safe and efficient opera�on of the system. To reduce the risk of injury, refer to Chart 3-2 for recommended cables. Please follow below steps to implement ba�ery connec�on: 1.
