2.0
2.0 TriStar Installation
The installation instructions describe solar battery charging. Specific
instructions for the load control and diversion modes are provided as notes.
2.1 General Information
The mounting location is important to the performance and operating life of
the controller. The environment must be dry and protected as noted below.
The controller may be installed in a ventilated enclosure with sealed batteries,
but never in a sealed battery enclosure or with vented batteries.
If the solar array exceeds the current rating of the controller, multiple TriStars
can be installed in parallel. Additional parallel controllers can also be added in
the future. The load controllers cannot be used in parallel. To parallel diversion
controllers, refer to Morningstar’s website.
If solar charging and load control are both required, two separate controllers
must be used.
Stranded wires to be connected to the terminals should be prepared
rst with e.g. clamped copper heads, etc. to avoid the possibility of one
conductor free out of the connection screw, and possible contact with the
metal enclosure.
WARNING: Solar and battery fuses or DC breakers
are required in the system. These protection devices are external to the
controller, and must be a maximum of 70 amps for the TriStar-PWM-45, and 90
amps for the TriStar-PWM-60/M.
AVERTISSEMENT: Solaire et batterie fusibles ou
disjoncteurs DC sont nécessaires dans le système. Ces dispositifs
de protection sont externes au contrôleur, et doivent être un maximum de 70
ampères pour le TriStar-PWM-45, et 90 ampères pour le TriStar-PWM-60/M.
WARNING: Installation must comply with all US National
Electrical Code and Canadian Electrical Code requirements. Breakers
and fuses may require lower ratings than referenced above, so as not to exceed
any specic wire ampacity.
AVERTISSEMENT: Installation doit être conforme à
toutes les requirments US National Electrical Code et Code Canadien
d'Electricité. Disjoncteurs et fusibles peuvent exiger des cotes inférieures que
mentionnés ci-dessus de manière à ne pas pour dépasser n'importe quel fils
particulier admissible.
Maximum battery short-circuit current rating must be less than the interrupt
current rating of the battery over-current protection device referenced above.
2.2 Installation Overview
The installation is straightforward, but it is important that each step is done
correctly and safely. A mistake can lead to dangerous voltage and current
levels. Be sure to carefully follow each instruction in Section 2.3 and observe
all cautions and warnings.
The following diagrams provide an overview of the connections and the
proper order.

Step Solar Charging and Load 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
(not for load control).
5. Connect battery voltage sense wires (recommended).
6. Connect the battery power wires to the TriStar. Then connect the
solar array wires (or load).
7. Connect a computer to the TriStar if making adjustments with
PC software.
8. Replace the cover.
