4.4 Grounding
Directly connect the ground terminal to class D grounding (third class grounding) with a
grounding resistance of 100 Ω or less. The grounding screw is provided in the rear of the unit. For
the grounding cable, use an electrical wire that has a conductor cross-sectional area of AWG14
or greater and that is based on outdoor specifications. Attach a round crimping terminal to the
end of the cable. Pass the round crimping terminal through the grounding screw in the rear of the
unit, and tighten it using a tightening torque of 1.69 N•m.

PoE Power Supply and Connection with
the Gateway Configuration PC
The power is fed from the PoE switch or the PoE injector to the gateway through the Ethernet
cable.
CAUTION
The compatibility-confirmed PoE switches are based on indoor specifications. When installing
the PoE switch outdoors, make sure that it will be enclosed in a waterproof box.
(1) Connect the Ethernet cable of the gateway to the PoE port. The gateway configuration PC
can be connected to any port.
(2) Turn the PoE switch on.
(3) Make sure that the power indicator LED (indicated by “PR”) lights up among the indicator
LEDs under the transparent cover at the bottom of the gateway.
