Figure 3-6. Removing the RS-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.
MeterBus Connection
TM
MeterBus networks use standard 4-wire or 6-wire RJ-11 telephone cables. If possible, pull the tele-
TM
phone 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.
Y-cable Connections for EMC-1 Use
TS-MPPT-30 and TS-MPPT-45 units can be Ethernet connected using the EMC-1 accessory and an
EMC-1 provided Y-cable. These models need to be connected to the EMC-1 with the Y-cable (DB-9
serial and RJ-11 plugs at the TS-MPPT) and an RJ-11 plug at the EMC-1.
28 Installation
Step 9 - Power Connections
CAUTION: Wiring Requirements
!
U.S. installed wiring must conform to all current U.S. NEC, ANSI/NFPA 70
requirements, and to any local regulations. Non-U.S. installations must meet all
national and local requirements of the country of installation.
WARNING: Fire Hazard
If multiple units are used in parallel for more charging current, the battery
conductor wiring must be sized for the total sum of all current ratings of the
combined controllers.
CAUTION: Risk of Fire and Shock
!
Connect battery terminals prior to the connection of array terminals. The battery
positive (+) terminal has a red cover, the solar positive (+) terminal has a yellow
cover.
AVERTISSEMENT : Risque d'incendie
Si plusieurs unités sont utilisées en parallèle pour plus de courant de charge, le câblage du
conducteur de la batterie doit être dimensionné pour la somme totale de tous les courants nominaux
des contrôleurs combinés.
PRUDENCE : Exigences de câblage
!
Le câblage installé aux États-Unis doit être conforme à toutes les exigences
actuelles du NEC américain, ANSI/NFPA 70 et à toute réglementation locale.
Non américain les installations doivent répondre à toutes les exigences
nationales et locales du pays d'installation.
PRUDENCE : Risque d'incendie et de décharge électrique
!
Branchez les bornes de la batterie avant la connexion des bornes de réseau.
La borne positive (+) de la batterie a un capuchon rouge, la borne positive (+)
solaire a un capuchon jaune.
WIRE SIZING
The four large power terminals are sized for 14 - 2 AWG (2.5 - 35 mm2) wire. The terminals are
rated for copper and aluminum conductors. Use UL-listed Class B or Class C stranded wire rated
for 300 Volt and 75C or higher. Copper is recommended due to the ease of use, good conductivity,
strength and lower thermal expansion properties.
It is critical that the ampacity (or current carrying capacity) of conductors is sufficient to handle the
maximum current of the power circuits. Good system design generally requires large conductor wires
that limit voltage drop losses to 2% or less.
See the APPENDIX A - Wire Sizing - for copper wire sizing instructions including minimum wire sizing
and voltage drop distance tables.
