be directly terminated inside the FDAP2 without an additional external junction box. Power
(both AC and DC) connection, Ethernet and Serial connections can be terminated inside
the FDAP2.
DC power wiring
When powered from an external DC source, the power cable should be terminated directly
onto the terminal block of the DC Ferrite Assembly. Connected wires then pass through
the mounted ferrites on the assembly board, which then connects to the two-position
terminal block on the Power Board. The polarity of the connector is marked next to the
connector on the Power Board. The power cable should be shielded, and the drain wire
grounded inside the enclosure as displayed in the following figure.
Secure all connections and wires and connect the cover-ground connection lug to the
enclosure cover to complete the wiring.
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 the following figure.
Ethernet and field DC power

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 meters
