Connect Power to the FBUS-HSE/H1 LD
Each FBUS-HSE/H1 LD on your network requires an 11-30 VDC power
supply.
The power connector is a 6-pin screw terminal power connector whose
pinout is shown in Figure 2-7.

Connect the primary power supply to the center V and C pair with the
positive and negative wires on your power cable in the V and C terminals,
respectively. You can connect an optional backup power supply to the left
V and C pair. The right V and C pair provides the same power supply as the
primary power supply.

(POST) that take several seconds and the green POWER LED is lit.
