6-1 Turning the Power ON

The DCP301 is not equipped with a power switch or protective fuses. If necessary, prepare these externally.

When a voltage of 90 to 264Vac is applied across terminals (1) and (2) on the DCP301, display appears for about 10s after which control and other operations are started. During controller startup until start of operations, the LEDs on the profile display light successively at uneven intervals clockwise from top right.
