PMO-C40, C40K & VLC40 for DR Systems
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.
Wiring Instructions
1. Follow the assembly instructions before wiring. Route the positive wire
through conduit (not included) to the DC side of the Power Module and
connect to the top of the PV array disconnect. Do not connect the array
positive directly to the C40 charge controller. Use a minimum of 6 AWG
wire. 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 bonding block. Connect the
frames of the PV Modules to the bonding block through ground wiring. The
PV negative and battery negatives are connected at the negative bonding
block. Do not connect the charge controller battery negative directly to the
battery.
3. Route all battery temperature sensor cables through the opening in the
tray of the module at the bottom right rear behind the DC disconnect
breakers. This allows the BTS cable(s) to be routed along
with the battery cables. There may be multiple
temperature sensors depending on the total number of
charge controllers and inverters in the system. Utilize all
available temperature sensors to maximize system
performance. Connect the temperature sensors to the
charge controllers through one of the openings in the rear
of the PM with a plastic grommet protecting the edge.
Place all temp sensors on the same battery and in the
middle of the battery bank.
