System Connectors - GE 040374 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, Use #14 [2.5mm
volt wire.
B
- Fault Contacts — Use 1 (N.O.), 2 (COM) and 3
(N.C.) to hook up a siren, light, etc. to alert you in
case of a fault. Contacts reverse state (1 [N.O.]
goes to 3 [N.C.] and vice versa) upon a fault
condition.
C
– Transfer Switch Communication (4 [TxRx] and
5 [TxRx GND]) — Connect to transfer switch
control board for communication interface
using 18AWG [1mm
D
– 6 (+LED) and 7 (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
- Ground Connection — Connect to transfer
switch ground wire.
H
- Neutral Connection — Connect to transfer
switch neutral wire
• For power output connection (Line 1, Line 2, Neutral, and Ground), refer to the following table:
> 300V, 75° C
* Reference NEC 2014 table 310.15 • Use National Electric Code for correction factors and wire size calculations.
• For transfer switch communication use #18 AWG [1mm
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].
* Metric system rounded for simplicity
NOTICE Neutral wire (H) must be connected to the
transfer switch Neutral wire.
DO NOT connect neutral and ground together
within the generator.
