Installation
3.1 General Information
WARNING: Equipment Damage or Risk of Explosion
Never install the TriStar MPPT 600V in an enclosure with vented/flooded batteries.
Battery fumes are flammable and will corrode and destroy the TriStar MPPT 600V
circuits.
!
CAUTION: Equipment Damage
When installing the TriStar MPPT 600V in an enclosure, ensure sufficient ventilation.
Installation in a sealed enclosure will lead to over-heating and a decreased product
lifetime.
AVERTISSEMENT: Endommagement de l’équipement ou risque d’explosion
N’installez jamais le TriStar MPPT 600V 600Vdans une enceinte avec des batteries à
évent/à électrolyte liquide. Les vapeurs des batteries sont inflammables et corroderont et
détruiront les circuits du TriStar MPPT 600V.
!
PRUDENCE: Endommagement de l’équipement
Assurez une ventilation suffisante en cas d’installation du TriStar MPPT 600V 600Vdans
une enceinte. L’installation dans une enceinte hermétique entraîne une surchauffe et une
réduction de la durée de vie du produit.
The installation is straight-forward, but it is important 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 this section.
READ ALL INSTRUCTIONS FIRST
before beginning installation.
The installation instructions are for installation of a negative grounded system. U.S National
Electrical Code (NEC) requirements are noted on occasion for convenience, however the in-
staller should have a complete understanding of NEC and UL requirements for photovoltaic
installations.
Solar and battery fuses or DC breakers are required in the system. These protection devices
are external to the TriStar MPPT 600V controller, and must be a maximum of 90 amps for the
TriStar MPPT 600V.
Maximum battery short-circuit current rating must be less than the interrupt current rating of the
battery over-current protection device referenced above.

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.

Recommended Tools:
• Wire strippers
• Wire cutters
• #2 & #0 Phillips screwdriver
• slotted screwdrivers
• Pliers
• Drill3/32” (2.5 mm) drill bit
• Level
• hack saw (cutting conduit)
3.2 Wiring Zones
The 600V solar circuits must be separated from the low voltage battery circuits and communica-
tion wiring within the wiring box. Figure 3-1 below shows the high voltage and low voltage zones
(shaded) within the wiring box. There is overlap in the zones as pictured because the removable
wiring divider separates the high voltage solar wiring and low voltage wiring. Solar high voltage
wiring should be routed below the removable wiring divider. The yellow

The battery wiring and all communication cables must only be routed within the low voltage wir-
ing zone. After the solar wiring is installed, the wiring divider should be secured in place, and the
battery cables routed above the divider. Detailed installation steps are provided in the following
sections.
NOTE:
If ALL field wiring, including communications cable, is rated for 600V, wiring zone separation is
not required. In this case, it may be more convenient to remove the high-low voltage wiring box divider,
and terminate conduit that contains mixed voltage conductors at one point
.
