EIA-485 Connection
The four (4) position EIA-485 connector on the TriStar MPPT 600V must be removed to access
the terminal screws. Remove the socket connector by firmly grasping the connector body and
pulling away from the circuit board as shown in figure 3-13.

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 traf-
fic. 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.
MeterBus
TM
Connection
MeterBus
TM
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.

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.
