Low Voltage connections to signal fault contacts, transfer switch communication and auxiliary 12VDC power are made via a

field connection terminal block in control board area. Compare this illustration with your generator to familiarize yourself with

the location of these connections.

System Connectors

- Two Pin Terminal Block — Used to connect utility

240 VAC from fuse block in ATS to the control board.

Connect only one wire per terminal.

- Fault Contacts — Use NO, COM and NC to hook up a

siren, light, etc. to alert you in case of a fault. Contacts

reverse state (NO goes to NC and vice versa) upon a

fault condition.

– Transfer Switch Communication (TxRx and TxRx

GND) — Connect to transfer switch control board for

communication interface using 18AWG twisted pair

wire.

– +LED and GND Connection — Not required for wireless

monitor included with unit. Available for optional

hardwired remote system status panel accessory,

#6154.

- Eight Pin Terminal Block — Used to connect signal

wires to the control board. Connect only one wire per

terminal.

- Power Connection (Line 1 and Line 2) — Power

connection to transfer switch.

- Neutral and Ground Connection — Connect to transfer

switch neutral and ground

• For power output connection (Line 1, Line 2, Neutral, and Ground), refer to the following table:

• Reference NEC 2011 table 310.15 (B) (16) • Use National Electric Code for correction factors and wire size calculations.

• For utility circuit connection (Utility A and Utility B) use #14 AWG minimum 300 volt wire.

• For transfer switch communication use #18 AWG twisted pair conductors, no greater than 200 ft in length, 300 volt wire.

• When connecting to the terminal block, fasten only one wire to each connector screw.

• Torque terminal block screws to 4.4 in-lb (0.49 Newton meter).

• Torque circuit breaker connections to 45 in-lb (5 Newton meter).
