Specialty Concepts ASC-Plus - Manual (Page 8)

INSTALLATION INSTRUCTIONS (continued) :
5. REMOVE POWER FROM BATTERY / PANELS: - Disconnect power from the
batteries and panels prior to running the wires to the controller.
6. RUN SYSTEM WIRING: - After disconnecting the power sources, run the wires from
the battery and solar panel to the location selected for the controller. The wires
should reach the location of the ASC-Plus and be secured with a little extra for strain
relief loops.
7. NOTE WIRE POLARITY: - Make sure to correctly mark the source and polarity of the
wires using colored wires or tags. Incorrect polarity may cause the ASC-Plus fuse to
blow.
8. ASC-Plus CONNECTION: - Wire the ASC-Plus according to Figure 1. The ASC-
Plus terminals accept up to 10 gauge bare wire. (When using 10 gauge wire, use
stranded wire and divide the end-wires into two equal sections and straddle the
terminal screw). If using crimp connections, be sure to crimp and solder.
9. INSTALL TEMPERATURE COMPENSATION (OPTION-A): - If included. Refer to
OPTIONS section.
10. COMPLETE LOAD CONNECTION: - Refer to Figure 1 to complete the load
connection for low-voltage load disconnect..
11. INSTALL FUSING IF NEEDED: - Add additional circuit protection if needed.
12. RECONNECT BATTERY AND ARRAY POWER: - No specific reconnect
sequence needs to be followed.
13. OPERATION: - Operation of the ASC-Plus is now fully automatic. If the battery
voltage is below the Full Charge Termination set-point (14.3 volts) and power is
available from the array, the ASC-Plus should start up in the charge mode.
Refer to OPERATION: RESETTING THE LVD CIRCUIT section for information on
how to activate the loads immediately after installation.
During operation, it is normal for the unit to feel warm (but not too hot to touch).
