Figure 3-9. Removing the EIA-485 socket connector
RS-232 Connection
The serial RS-232 port is a standard 9-pin (DB9) female connector. A low-profile serial connector
is recommended to save room in the wiring box.
NOTE:
The RS-232 and EIA-485 ports share hardware. Both ports cannot be used simultaneously.
REMARQUE :
Les ports RS-232 et EIA-485 partagent le matériel. Ils ne peuvent pas être utilisés simultanément.
Ethernet Connection
The RJ-45 Ethernet jack features two (2) indicator LEDs for connection status and network
traffic. Use CAT-5 or CAT-5e twisted pair cable and RJ-45 plugs. If possible, pull the network
cable through conduit before crimping on the RJ-45 connectors. If using pre-assembled cables,
take care not to damage the plugs when the cables are pulled through conduit.

Connection

networks use standard 4-wire or 6-wire RJ-11 telephone cables. If possible, pull the
telephone cable through conduit before crimping on the RJ-11 connectors. If using
pre-assembled cables, take care not to damage the plugs when the cables are pulled through
conduit.
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.

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 TS-MPPT-600V-TR 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.
