2. Feed the wires from the transformer through the
left-hand hole in the bottom of the controller. Pull
about 10" (25.5 cm) of the wire out through the front
of the compartment. To provide strain relief, loop
the wire into a simple overhand knot, leaving the
ends of the wire between 3" and 4" (7.7 cm and 10.2
cm) beyond the knot. Pull the excess wire back out
of the bottom of the controller until the knot reaches
the hole (see illustration).
3. Connect the green wire from the transformer to
the far left screw (GND) on the terminal strip. Con-
nect each of the two remaining wires to one of the
screws labeled "24 VAC".
4. Plug the transformer into any standard, 3-prong
117 VAC grounded wall outlet.
U.S. VERSION, 117-120 VAC, 60HZ)
1. Unscrew and remove the cover of the junction box
and remove the clip that is supplied with it. Carefully
punch in and remove knockout "E" in the end of the
junction box and punch out the two small holes "F" &
"G" (see illustration).
3. With code-approved wire connectors, connect the
green wire (sometimes this a completely bare, cop-
per wire) from the power source to the green/yellow
wire from the controller. In a similar manner, con-
nect each of the two remaining power source wires
to one of the controller’s input wires (see illustra-
tion).
4. Carefully coil or bend the wires to fit them and
their connectors into the junction box. Reattach the
cover to the junction box.
OUTDOOR CONTROLLER (INTERNATIONAL
VERSION, 230 VAC)
The main power connections for the 230 VA. ver-
sions of the E-Class controller are very similar to
the U.S. version described previously. The only ex-
ception is that there are only two main power input
wires coming from the controller. Connect each of
these two input wires to one of the power wires
coming from the 230 VAC power source (see illus-
tration). Use wire connectors that meet local electri-
cal codes.
2. Cut the power input wires from the controller and
the supply wires from the power source to a conve-
nient length, approximately 3" (75 mm) for making
wire connections. Strip approximately 1/2" (12.5
mm) of the installation from the end of each wire
(see illustration).
INDOOR CONTROLLER (117-120 VOLT 60 HZ
VERSION)
1. Before connecting the external transformer to the
controller, make sure the transformer is NOT
plugged in.
