Option 2: Ethernet connection with AC power
To install the Door Station with Ethernet and AC power:
1 Plug the Ethernet cable into the Door Station (see Figure 4).
2 Connect a ground wire from the Door Station to one of the
back box lugs (see Figure 12).
3 Connect a second earth ground or house ground wire from
the second back box lug to the home. See "Grounding
requirements" for details about earth grounding.
4 Connect the neutral (N) and hot (L) wires to the AC power
source for the Door Station according to national and local
electrical codes.
Tip: The hot or (L) wire's connector is closest to the
bottom of the Door Station's plate.
5 If your installation requires alternative wires and the use of a
terminal block, strip the power wires to 1/4" (6 mm) on the
end, if necessary.

Option 3: Ethernet connection with DC power
To install the Door Station with Ethernet and DC power:
1 Plug the Ethernet cable into the Door Station (see Figure 5).
2 Connect a ground wire from the Door Station to one of the
back box lugs (see Figure 12).
3 Connect a second earth ground or house ground wire from
the second back box lug to the home. See "Grounding
requirements" for details about earth grounding.
4 Connect the negative (-) and positive (+) wires to the DC
power source for the Door Station according to national and
local electrical codes.
Tip: The positive (+) wire's connector is located on the
bottom left side of the Door Station's plate.
5 If your installation requires alternative wires and the use of a
terminal block, strip the power wires to 1/4" (6 mm) on the
end, if necessary.
