Communication Wiring

The communication terminal requires 10 wires.

Route a multi-conductor cable (min AWG 18 max AWG 12)

from the generator to the 12-position center Terminal Block in

the ARL through a smaller knockout. Strip wires 1/4 inch and

connect each numbered wire to the terminal block in sequence

from left to right starting with 1 in the left-most position.

Note that some of the terminal block positions are

deliberately left unused (TB2-4 and TB2-8.)

Each wire is connected by pushing the nylon release lever

backwards to open the terminal clamp, inserting the stripped

wire into the terminal opening, and releasing the terminal

clamp.

 CAUTION

Care should be taken not to overstress the nylon release

levers.

NOTICE

See the table on page 8 for proper wire routing to both the

HSB connector and the ATS connector.

The 10-position communication terminal will connect to your

Home Standby. This connector is provided with the Home

Standby Generator. Cable is not provided.

 CAUTION

Ensure power from the utility is turned off until all

communication wiring and line voltage wiring is complete.

Failure to comply may result in blown circuit board fuses,

which are not covered by warranty.
