Remove the existing power
transformer
You must replace the existing power transformer in the
ESP-LX PLUS controller with the new power transformer
included with the Module Kit. First, you will remove the
existing transformer:
• Disconnect the transformer from the ESP-LX PLUS ter-
minal board.
•
With the door and face panel removed, locate the high-
voltage compartment in the lower left corner of the
controller cabinet.
• Remove the screw on the right edge of the compart-
ment cover, then swing the cover open to expose the
transformer’s primary input wires.
• Disconnect the transformer’s primary input wires.
• Locate the nut and washer that secure the existing
transformer.
• Use a hammer and screwdriver to tap on the nut to
loosen it. Once loose, remove the nut and washer from
the power transformer’s nipple. Retain the nut and
washer.
• Push the power transformer’s nipple into the cabinet
until it clears the hole. Lift the power transformer out of
the controller cabinet.
