Figure 7: Ethernet and field DC power
Attention
For installations that require CE-mark compliance, the DC power source must be a CE-mark approved
power supply. In addition, the DC cable between the approved DC power source must be no more than
3.0 meters (9.8 feet) from the FDAP1/FDAP2
.
3.12.2 AC power wiring
When powered from an external AC source, the power cable should be terminated at the terminal
block on the AC/DC conversion module, marked as 24 VDC Power Brick as displayed in “Figure
8: Ethernet and field AC power”.
(1) To facilitate wiring, remove the Power Brick assembly from the enclosure by loosening the two
retaining screws and sliding the brick assembly out.
(2) Terminate the AC cables at the AC terminal block on the Power Brick module. The module has
polarity markings for Live (L), Neutral (N) and Ground.
(3) Ensure that all connections are secure and then slide the module back into the enclosure and secure
it with the retaining screws.
(4) Secure all connections and wires and connect the cover-ground connection lug to the enclosure
cover to complete the wiring.
