System Connectors - GE 40350 Installation And Start-Up Manual

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
control board for communication interface
using 18AWG twisted pair wire.
D
– +LeD and GnD connection — Not required for
wireless monitor included with unit. Available
for optional hardwired remote system status
panel accessory, #6154.
e
- eight Pin terminal Block — Used to connect
signal wires to the control board. Connect only
one wire per terminal.
f
- Power connection (Line 1 and Line 2) — Power
connection to transfer switch.
G
- neutral and Ground connection — Connect to
transfer switch neutral and ground
• 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).
