Figure 2.2b Installation Wiring for Diversion Charge Control
NOTE: TriStar negative terminals are common negative.
Steps #3 and #6 are required for all installations.
Steps #4, #5, and #7 are optional.
Step Diversion Charge Control
1.
Remove the access cover
2.
Mount the TriStar using the enclosed template.
3.
Adjust the 8 switches in the DIP switch. Each switch must be in the
correct position.
4.
Attach the RTS if battery charging will be temperature compensated.
5.
Connect battery voltage sense wires (recommended).
6.
Connect the battery power wires to the TriStar. Then connect the
diversion load wires.

PC software.
8.
Replace the cover.
2.3 Installation Steps
The TriStar controller must be installed properly and in accordance with the
local and national electrical codes. It is also important that the installation be
done safely, correctly and completely to realize all the benefits that the TriStar
can provide for your solar system.
Refer to Sections 4.0 and 9.0 for information about the TriStar’s standard
battery charging programs and general charging needs for different
battery types. Refer to Section 5.0 for load control information, and
Section 6.0 for diversion.
Recommended tools:
• wire cutter
• phillips screwdrivers
• wire stripper
• torque wrench (to 50 in-lb)
• slotted screw drivers
• flashlight
Before starting the installation, review these safety notes:
• Do not exceed a battery voltage of 48V nominal (24 cells). Do not use a
battery less than 12V (6 cells).
• Do not connect a solar input greater than a nominal 48V array for battery
charging. Never exceed a Voc (open-circuit voltage) of 125V.
• Charge only 12, 24, or 48 volt lead-acid batteries when using the standard
battery charging programs in the TriStar.
• Verify the nominal charging voltage is the same as the nominal battery
voltage.
• Do not install a TriStar in a sealed compartment with batteries.
• Never open the TriStar access cover unless both the solar and battery
power has been disconnected.
• Never allow the solar array to be connected to the TriStar with the battery
disconnected. This can be a dangerous condition with high open-circuit solar
voltages present at the terminals.
Follow the installation steps in order: #1 through #8
Step 1 - Remove the Cover
Remove the 4 screws in the front cover. Lift the cover until the top edge clears
the heat sink, and set it aside. If an LCD meter display is attached
to the cover, disconnect the RJ-11 connector at the meter for access.
CAUTION: Do not remove the cover if power is present at any of the
terminals. Verify that all power sources to the controller are disconnected.
PRUDENCE : N’enlevez pas le couvercle en cas de tension à une des
bornes. Vérifiez que toutes les sources d’alimentation au contrôleur sont
déconnectées.
Step 2 - Mounting
Locate the TriStar on a wall protected from direct sun, high temperatures, and
water. Do not install in a confined area where battery gasses can accumulate.
NOTE: When mounting the TriStar, make sure the air flow around the
controller and heat sink is not obstructed. There should be open space above
and below the heat sink, and at least 75 mm (3 inches) clearance around the
heat sink to allow free air flow for cooling.
REMARQUE : Lors du montage du TriStar, assurez-vous que l’écoulement
d’air autour du contrôleur et du puits de chaleur n’est pas obstrué. Un espace
doit se trouver au-dessus et en dessous du puits de chaleur et un
dégagement de 75 mm (3 po) doit exister autour du puits de chaleur pour
permettre l’écoulement de l’air à des fins de refroidissement.
Before starting the installation, place the TriStar on the wall where it will be
mounted and determine where the wires will enter the controller (bottom, side,
back). Remove the appropriate knockouts before mounting the controller. The
knockouts are sized for 1 inch and 1.25 inch conduit.
