13. Using installer supplied 300VAC or greater copper
conductor, connect transfer switch "GROUND" terminal
to generator control panel "GROUND" terminal.
Assure generator equipment grounding conductor is
connected per applicable federal, state and local codes,
standards and regulations.
14. Using installer supplied 300VAC or greater minimum
#14 AWG copper conductor, connect transfer switch
"UTILITY 240 VAC" terminals to generator's "240 VAC"
terminals via two-pin connector supplied with generator.
15. Using installer supplied 300 volt 75°C-90°C, #18 AWG
twisted pair copper conductors, no greater than 200 ft in
length, connect "T/R" and "GND" terminals on transfer
switch control board (B) to the generator's control
panel (A) "TxRx" and "TxRx GND" terminals via ten-pin
connector supplied with generator.

16. Tighten all wire connections/fasteners to proper torque.
See label inside transfer switch enclosure for proper
torque values. Replace all protective barriers.
Supervisory Control Wiring
An air conditioner can be used with the supervisory contacts
on either terminals A-A or B-B. Terminals A-A can only be
used with supervisory control. Large loads can only be used
with contactor control on terminals B-B. Examples of each
system are described below.
1. The terminal strip on the transfer switch control board
has four connections for customer use. There are two
sets of "Normally Closed" contacts available. They will
be activated when generator power is required. These
can be used for supervisory control of large connected
loads on generator. Loads will be allowed to operate if
there is enough generator power available.
For installer convenience, there are two wireways
provided to help keep supervisory load wires organized.
2. Terminals "A-A" on transfer switch control board
are rated for 24 VAC. Connect these contacts in
series between air conditioner thermostat and air
conditioner contactor.

3. Terminals "B-B" on transfer switch control board are
rated for 1 Amp 125 VAC. When connected with
an installer supplied contactor, it can be used to
control a large load, such as an electric water heater.
Contacts are connected in series with the contactor
control circuit.
