TriStar MPPT-600V-TR Operator's Manual
Step 6 - Power Connections
NOTE:
To comply with the NEC, the TS-MPPT-600V-TR 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 TS-MPPT-600V-TR doit 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 - 33.6 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 solar array and
battery bank to the TS-MPPT-600V-TR with a maximum of 2% voltage drop.
Minimum Wire Size (Field Wiring Connections Only)
The NEC requires that the wires carrying the system current never exceed 80% of the conduc-
tor's current rating. Table 3.2 below provides the minimum size of copper wire for battery output
connections allowed by NEC for both TS-MPPT-600V-TR 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-TR comes pre-wired with #6 AWG copper wire. If replacement
is required, do not exceed #6 AWG wire.
** The TS-MPPT-60-600V-48-DB-TR comes pre-wired with #6 AWG copper wire. If replacement
is required, use only copper conductors.

Over-Current Protection and 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.
