Figure 2. The pin designations of this connector are as
follows; see Figure 2 for pin rotation.

Voltages less than 10VDC will shut the unit down.
When power is restored, the ON switch will need to be
held down for more than 3 seconds.
Voltages in excess of 30VDC will damage the unit. It is
extremely important to ensure that the power supply is
well conditioned with surge protection. This is
especially true for vehicular electrical systems, which
can create voltage spikes far in excess of 30VDC.
