1. The DC controller will be burned out when the open-circuit voltage is higher than setting
value.
2. The DC controller must match with the recommended solar pumps.
3. Do not use the DC controller for other pumps. If cause any problems because of this
reason. We do not bare any responsibility.
4. For the perfect performance and long-life working, the DC controller should be kept
away from strike, shake, sunshine, salt mist, oil mist and etc.
5. Because of the power loss from cable, try to use the shortest cable.
6. While use longer cable, the cable connecting DC controller and solar panels should be
over 4mm
2
(Do not use single wire type). While the cable between DC controller and
pump within 30m, the cable should be at least 2mm

. While over 30m, the cable should
be at least 4mm
