Specialty Concepts ASC - Manual (Page 8)

INSTALLATION INSTRUCTIONS (continued) :
4. COMPLETE THE INSTALLATION OF ARRAY, BATTERIES AND LOAD: - Follow the
manufacturer's instructions for mounting and wiring the solar panel, batteries and the
load. Install with the correct series-parallel configuration to insure proper system
voltage and current
5. REMOVE POWER FROM BATTERY / PANELS (if needed): - Prior to running the
wires to the ASC, be sure that power is disconnected from the batteries and
panels
6. RUN SYSTEM WIRING: - Run the wires from the battery and solar panel to the
ASC controller. The wires should reach the location of the ASC and be secured
with a little extra for strain relief loops.
7. NOTE WIRE POLARITY: - Make sure to correctly note the source and polarity of
the wires using colored wires or tags. Incorrect polarity may damage the
ASC.
8. ASC CONNECTION: - Wire the ASC according to Figure 1. Do not use a jumper
across the Array(-) and Batt(-) terminals. If using crimp connections, be sure to
crimp and solder.
9. INSTALL TEMPERATURE COMPENSATION (OPTION-A): - If included. The
cable’s sensor needs to mount onto the side of the batteries. Refer to
“OPTIONS” section.
10. COMPLETE LVD CONNECTION (OPTION-E): - Refer to Figure 2 to complete
the load connection for low-voltage load disconnect. Be sure to run a separate wire
from the battery (+) terminal to the ASC’s COM terminal. Do not use a jumper from the
ASC’s BATT(+) terminal to the COM position.
Refer to “OPTIONS” section.
11. INSTALL FUSING AS NEEDED: - Add circuit protection where needed. A
fuse and disconnect switch, rated for the nominal current of the ASC, should be
installed on the Battery (+) run of the ASC. See Figures 1 or 2.
12. CONNECT BATTERY AND ARRAY POWER
