ESPLXD-ET Controller
Connecting Power to the Controller
Connect Ground Wire
The ESPLXD-ET controller is equipped with built-in electrical surge
protection. For this system to function, you must properly ground the
controller.

WARNING:
The ground wire MUST be connected to provide
electrical surge protection. Connect the controller to the
grounding grid using at least a #8 AWG (10 mm) or #10 AWG
(6 mm) bare copper wire. The wires should be as short and as
straight as possible. You will void the controller warranty if you do
not ground the controller to a minimum resistance of five ohms.
Connect Power Source
The ESPLXD-ET controller has an internal transformer that reduces
supply voltage (120 VAC in U.S. models; 230 VAC in international
models; 240 VAC in Australian models) to 24 VAC to operate the
decoders connected to the controller. You will need to connect power
supply wires to the transformer’s three wires.

WARNING:
Electric shock can cause severe injury or death. Make
sure power supply is turned OFF before connecting power wires.

WARNING:
All electrical connections and wiring runs must be
made according to local building codes.
