2.0 Battery Installation and Wiring
Load batteries into cabinet with the positive terminals (+)
facing forward. Coat the hardware and battery terminals
with an approved battery terminal corrosion inhibitor such as
NCP-2
®
and assemble the cables and hardware as shown in
the illustrations below. Torque hardware to 110 in-lbs (12.4
Nm). If M6 hardware is used, torque to 120 in-lbs (15.6 Nm).
With a Midtronics
®
Conductance meter (Celltron
®
Essential,
Celltron
®
Advanced or equivalent) measure the conductance
value (MHOS) of each battery and record for use in Section
6.2
Battery Configuration.
Also, record the battery date code
on the battery label for entry on the DATE SET screen.

Verify battery voltage, cable color, connection
and polarity are correct before proceeding.
WARNING! ELECTRICAL HAZARD
Use 1/4-20 x 3/4" (19 mm) bolts for threaded insert terminals. If using a spacer for the in-line fuse link,

2. Loosen the terminal screw and move the output voltage wire
(Fig. 3-1) to the desired output voltage position on the terminal strip.
3. Torque the terminal block screw to 7 in-lbs (0.79 Nm) to secure the
output voltage wire.
4. Reinstall the Inverter Module.
