• Check the installation, see 3.4.
3.2.2 Power requirements
The controller requires a power supply of 18VDC ~ 36VDC, 12W DC. There is an internal DC / DC switching
power supply, which need surge to start. A low-output impedance power supply (for example, using storage
battery directly for power supply) is required and the controller power on and off by a power switch adopted at
the terminal 2 to meet the switching power timing requirements. The AC - DC converter power supply is not
recommended. For the correct power connection , see figure 3-1.
