Installing the new transformer
Now you are ready to install the new power transformer.
Place the new power transformer into the same position
as the old transformer and slide the transformer’s nipple
through the hole at the top of the high-voltage compart-
ment.
Thread the washer and the nut on to the new power trans-
former’s nipple. Finger-tighten the nut. Final-tighten the
nut by lightly tapping a screwdriver placed against the
nut.
Connections to the Main Power Source
The three main power input wires for the standard 120-
volt, 60 Hz/ AC transformer are black, white, and green.
The international version 230-volt, 50 Hz wires are brown,
blue, and green and yellow.
To connect the power input wires to the main power
source,
• If you have the standard 120-volt, 60 Hz model, use
wire nuts to connect the black wire to the power source
hot wire, the white wire to the common wire, and the
green wire to the ground wire.
OR
• If you have a 230-volt or 240-volt, 50 Hz model, use
wire nuts to connect the brown wire to the power
source hot wire, and the blue to the power source com-
mon wire. Connect the green and yellow wire to the
ground wire.
• Close the high voltage compartment
Reconnecting the power
Reconnect the controller to the power source.
• Connect the transformer’s three wires (two oranges and
one green) cable to the terminal board
Note: If you have a 240 VAC, 50 Hz model,
your transformer will have only two orange
wires for connection to the terminal board.
There will be no green ground wire.
