ELECTRICAL INSTALLATION
STEP 1
!
WARNING: SINGLE PHASE AC ONLY
At the “EMI Board”:
a. Set the “Voltage Selector” according
to the supply voltage (115V or 230V).
b. Connect the incoming power wires
to the terminals as shown in the
illustration.
c. Ground the ECU cabinet according to
local code or guidelines.
d. Turn on the main facility breaker and
verify that all three (3) Status LEDs are
illuminated on the EMI Board.
Tips for proper ground installation:
To minimize the effects caused by lightning, follow
these guidelines:
• Use a ground rod to provide a ground reference.
• Consult your city code and be aware of
underground services in the site of the gate
operator to prevent inconveniences.
• Always use a single bonding point for grounding.
• All ground wires must be as short and as thick as
possible.
• Prevent unnecessary turns or loops in all ground
wires.
STEP 2
At the Control Board:
a. Reinstall the Control Board Mounting
Plate with the Control Board.
b. Connect the outbound wires from the
Toroidal Transformer to the Green
and White “AC” wires of the “Power
Harness”. Polarity is not important.
Verify the “POWER” LED is illuminated
solid.
c. Reconnect all other harnesses.

! Caution: Always turn off power breakers when working with high voltage. DO NOT
connect the “Power Harness” to the Control Board until the electrical installation is
complete and ready for verification. To reduce the risk of electric shock, this equipment
(external plug-in transformer) has a grounding type Plug, that has a third (grounding) pin. This
plug will only t into a grounding type outlet. If the plug does not t into the outlet, contact a
qualied electrician to install the proper outlet. Do not change the plug in any way.
