Hunter ACC-99D User Manual

5
The ACC can operate with either 120 VAC or 230 VAC power,
depending on how the incoming AC wires are connected.
Supply wires must be 14 AWG (2 mm) or larger.
The ACC is prewired for 120V operation but can easily be
changed to 230V.
Consult or hire a licensed electrician for these connections
as required.
• Turn AC power off at the source, and verify that it is
off.
• Remove the wiring compartment screws and the
wiring compartment door.
• Strip approximately ½" (13 mm) of insulation from the
end of each of the AC power wires, and route into the
wiring compartment through the conduit.
• Locate the white plastic terminal block, and wire
according to the following diagrams.
For 120V~ operation, connect the incoming black power
wire (hot) to align in the wiring block with the black wire
lead from the transformer.
Insert the incoming black wire lead into the hole opposite
the black transformer wire and tighten screw securely.
Connect the incoming neutral (white) wire to align with the
blue lead from the transformer.
Cap off the brown (230 VAC) wire if applying 120V and not
using a wiring block. The brown wire will be hot and have a
230V charge.

The green, or green-and-yellow safety ground
may not be required or permitted with this
floating ground, double-insulated transformer.
If desired and permitted, connect it to the earth
ground lug on the controller. Install a conduit
junction T-box below the supplied junction box
in the controller, and route the safety ground
out of the T to the earth ground lug of the
controller.
Tighten screw and replace cover.
For 230V~ operation, connect the incoming power
wire (hot, brown in many wiring standards) to align
in the wiring block with the brown wire lead from the
transformer. Connect the incoming Neutral (blue in some
international standards) wire to align with the blue lead
from the transformer. Tighten screws and replace cover.
Apply AC~ power and test. Refer to Earth Ground and
Station Wiring sections for additional connections.
