Installation
Minimum Wire Size (Field Wiring Connections Only)
The NEC requires that the wires carrying the system current never exceed 80% of the
conductor's current rating. Table 3.2 below provides the minimum size of copper wire for battery
output connections allowed by NEC for both TriStar MPPT 600V models when the output current
equals the full nameplate rating. Wire types rated for 75°C and 90°C are included.
* The TS-MPPT-60-600V-48-DB comes pre-wired with #6 AWG copper wire. If replacement is
required, use #6 AWG or larger wire.
** The TS-MPPT-60-600V-48-DB comes pre-wired with #6 AWG copper wire. If replacement is
required, use only copper conductors.

Disconnects
WARNING: Shock Hazard
Fuses, circuit breakers, and disconnect switches should never open grounded system conductors. Only
GFDI devices are permitted to disconnect grounded conductors.
AVERTISSEMENT : Risque de décharge électrique
Les fusibles, coupe-circuits et interrupteurs ne doivent jamais ouvrir les conducteurs du système mis à la
terre. Seuls les dispositifs GFDI sont autorisés à déconnecter les conducteurs reliés mis à la terre.
Circuit breakers or fuses must be installed in both the battery and solar circuits.
The protection
device ratings and installation methods must conform to NEC requirements.
WARNING:
The TriStar MPPT 600V is not protected against PV short circuit faults. A breaker
or fuse, close to the controller, in the (+) PV input wire will also protect the PV wiring
against a short that may draw battery current backwards through the product.
AVERTISSEMENT :
Le TS-MPPT-600V-TR n’est pas protégé contre les défauts de court-circuit de PV.
Un disjoncteur fusible, ou près du programmateur, dans le signe (+) PV d’entrée fil protégera également le
câblage PV contre un court-circuit qui peut tirer une batterie courant en arrière à travers le produit.
Connect the Power Wires - TS-MPPT-60-600V-48
WARNING: Shock Hazard
The solar PV power source can produce open-circuit voltages in excess of 500 Vdc
when in sunlight. Verify that the solar input breaker or disconnect has been opened
(disconnected) before installing the system wires.
AVERTISSEMENT : Risque de décharge électrique
Le réseau PV solaire peut produire des tensions de circuit ouvert supérieures à 500 V cc
à la lumière du soleil. Vérifiez que le coupe-circuit ou l’interrupteur d’entrée solaire a été
ouvert (déconnexion) avant d’installer les câbles du système.

Step 6 - Power Connections
NOTE:
To comply with the NEC, the TriStar MPPT 600V must be installed using wiring methods in
accordance with the latest edition of the National Electric Code, NFPA 70.
REMARQUE :
Pour la conformité CNE, le TriStar MPPT 600V 600Vdoit être installé selon des méthodes de
câblage conformes à la dernière édition du Code électrique national, NFPA 70.
Wire Size
The four large power terminals are sized for 14 - 2 AWG (2.5 - 34 mm
2
) wire.* The terminals are
rated for copper and aluminum conductors.** Use only UL-listed Class B 300 Volt stranded wire
for battery connections. Good system design generally requires large conductor wires for the
solar and battery connections that limit voltage drop losses to 2% or less. The wire tables in the
appendix on pages 77-80 provide wire sizing information for connecting the power source and
battery bank to the TriStar MPPT 600V with a maximum of 2% voltage drop.
