Connect power cables and Ethernet cables for FDAP Gen3

FDAP Gen3 has one Ethernet cable and one power cable. Ethernet interconnection is limited to installations
outside Class I Division 1, Zone 0/1 locations. You have to construct conduit and cable runs for power and
Ethernet. The FDAP Gen3 can be powered directly by external DC power supply such as distributed DC
source. Ensure that all wires inside the enclosure are routed and secured properly as displayed in "Figure 7:
Ethernet and field DC power". The FDAP Gen3 has integrated terminal blocks that allow field wiring to be
directly terminated inside the FDAP Gen3 without an additional external junction box. DC Power connection,
Ethernet and Serial connections can be terminated inside the FDAP Gen3.
Attention
RS-485 or Ethernet can be used one at a time to meet IP (66/67) requirements.

3.11.1 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 "Figure 7: Ethernet and field DC power".
Secure all connections and wires and connect the cover-ground connection lug to the enclosure cover to
complete the wiring.
