PMO-40, C40k & VLC40 for Sinewave Systems
The wiring scheme shown in this view meets NEC code requirements by
using the battery disconnect of the inverter as the overload/disconnect
device. Alternative methods of wiring the C40’s may be needed depending
upon your application. Kits are shipped with maximum wire lengths
pre-cut. Trimmed the uncrimped end to the length found in the Wire
Length table according to the C40’s mounting position.
Place double-sided tape on the back panel of the C40 in the location
shown. Drill the dimples in the back plane of the PM in the approximate
location shown. When installing multiple C40’s, install them in the
sequence shown above the wire length table. Bundle excess or loose
wires. This option requires the use of a bare grounding conductor between
the DCBB and a rod or pipe driven into the earth.

Wiring Instructions
1. Follow the assembly instructions before wiring. Route
the PV array positive wire through conduit (not included)
to the DC side of the PM and connect to the top of the PV
array disconnect. Do not connect the array positive
directly to the C40 charge controller. If more than one
charge controller is utilized, the modules in the array
should be divided equally between the controllers.
2. Connect the PV array negative to the ground bonding
block (DCBB). Connect the frames of the PV modules to
the ground bonding block through the negative array
cables. The PV negative and battery negatives are
connected at the ground bonding block. Do not connect
the charge controller battery negative directly to the
battery.
