Power

To connect DC or AC power to the 8620, connect the power wires to the appropriate terminals supplied with the 8620 DET.

Note Before connecting power wires to the 8620 DET, ensure that power is switched off and that the 8620 DET is correctly grounded.

DC Wiring

1.Connect the 20 - 72 VDC positive wire to the bottom of the terminal switch as shown in Figure 3-1.

2.Connect the negative wire to Terminal Block Black.

AC Wiring

1.Connect the hot wire to Terminal Switch as shown in Figure 3-1.

2.Connect the neutral wire to Terminal as shown in Figure 3-1.

3.Connect the ground wire to the ground.

Communications

RS-485 is the default setting used for Com 2 as shown in Figure 3-1.
