System Connectors

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.

A- 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.

B- 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.

C– Transfer Switch Communication (TxRx and

 

TxRx GND) — Connect to transfer switch

•For power output connection (Line 1, Line 2, Neutral, and Ground), 300V, 10 AWG copper wire, or 300V, 8 AWG aluminum wire, (ref. NEC Table 310.16, 100 ft. 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).
