Installation Instructions for SEDM6-40
1.
Complete the installation and test the operation of the PVCM40D-MPT charge control module.
2.
Before mounting the SEDM6-40 module, plug in a short cat5e network cable into both, the
PVCM40D-MPT controller’s RJ-45 jack and the SEDM6-40 display’s RJ-45 jack and verify that all
readings work properly.
3.
Next measure your battery voltage at the battery with a volt meter, then calibrate the display’s
battery voltage reading by selecting the battery voltage setting on the display and then adjusting the
P2 potentiometer on the back of the d/- 1/4 turn on the adjustment pot so it reads correctly.
4.
Next remove the fuse from the controller’s PV in-line fuse holder and measure the voltage on the PV
side of the fuse clip and ground. Re-insert the fuse and scroll down to the solar panel voltage reading
on the display and adjust P4 potentiometric on the back of the d/- 1/4 turn on the
adjustment pot so it reads correctly.
5.
Determine the mounting method to be used, surface-cutout or single electrical box ring.
6.
For surface-cutout mounting, place the template (found on page 20 of this manual) over the desired
mounting location and mark through the template the two mounting screw locations. Drill two pilot
holes into the cabinet or mounting surface at the marked locations. Use a Phillips screw driver to
drive the screws into the mounting surface before mounting the display module. Back out the screws,
cut-out the template leaving the mounting screw areas and attach the template with the screws to
the mounting surface. Draw around the template on the mounting surface marking through the
template around the mounting screw tabs. Carefully cut out the marked area using a hole saw or
rotary tool leaving the mounting screw areas.
7.
For single gang electrical box ring mounting, use the ring as a templet and mark the area to be cut
out. Carefully cut area for the mounting ring, mount the box securely and install optional conduit if
desired.
8.
Unplug the short network cable from both the controller and display. Next route or pull the display
end of the network cable into the mounting area or electrical box, being careful not to damage the RJ-
45 plug.
9.
Plug the network cable into the controller’s RJ-45 jack, then after pulling it through the cutout hole,
plug it into the display’s RJ45 jack, the SEDM will power up turning on its backlight, and use the
select button to scroll thru and to verify the readings. Push any excess CAT-5 wire back into the hole
and mount the display. Insert the screws through the front of the SEDM6-40 module and into the
holes and tighten by hand with a Philips screwdriver to avoid damaging the SEDM6-40 display.
10.
Use grease or silicone to cover the controller’s end of the
Cat5e
network cable plug to avoid
corrosion.
