Infinity S (NE-S) Dual Voltage Power System
Quick Start Guide
NES4812-23-AC1-PS4-DC1E-LVBD
Read and follow all safety statements and precautions in this guide.
Tools Required:
Cable Crimpers Torque Wrench (0-240 in-lb / 28Nm) 5/16”, 7/16” and ½” nut drivers
Screw Drivers (#1 Flat & #2 Phillips) Wire cutters and strippers
Step 1 - Mount the System
Mount the system with a minimum gap of 3 inches behind the system to allow proper airflow.
1. Attach the system to the frame using a minimum of twelve (six on each side) 12-24 screws (provided).
Torque to 35 in-lb (4 Nm) - 5/16” socket.
Step 2 – Connect Chassis and DC reference (CO) ground
Chassis Ground lug - #10 or 1/4” on 5/8” centers (not provided).
Minimum 10 AWG recommended.
Torque to 10-32 screws to 30 in-lb (3.4 Nm) – 5/16” Socket.
DC reference ground lug - 5/16” or 3/8” on 1” centers (not provided).
Torque to 160 in-lb.
Note: If connecting chassis ground to frame surface remove non-conductive frame coating and apply antioxidant for
connection.

Step 3 – Connect AC inputs
Connect 120/208/220VAC at rear of each
rectifier shelf.
Danger: Turn OFF and lock-out tag-out the AC
source before making AC connections. When
connecting to AC mains, follow all local and
national wiring rules.
Caution: When routing AC ensure cables do
not come in contact with sharp or rough
surfaces that may damage insulation and
cause a short circuit.
Rectifiers numbers are labeled at each AC
input.
AC terminal connections are labeled at each position (L1, L2/N, and Gnd).
AC Terminal Block is in the AC box on the rear of the rectifier shelf
Connect AC input cord to the detachable input terminal block in the wiring box – knock out for ¾” conduit or cord grip.
Strip and torque per the table. Pull on wire to verify secure connection.

CAUTION: Verify battery voltage and polarity with a
voltmeter before connecting.
Distribution panels are each equipped with 20 (19” panel) or 26 (23” panel) bullet-style distribution positions. Each
position is selectable between Primary or Secondary (Converter) Voltage outputs.
Breaker sizes up to 250A, TPS fuses to 70A and GMT fuses to 12A are available.
