Specialty Concepts SC1 - Manual (Page 5)

INSTALLATION INSTRUCTIONS:
1. LOCATION: - A suitable location must be found for mounting the SC1. The unit should be
mounted on a vertical surface and be as close as possible to the batteries to avoid errors in
battery voltage reading. DO NOT block the ventilation holes on the top and bottom of the SC1.
On units with temperature compensation (Option A), the sensor wire is 10 feet long and
should reach the battery bank if possible. For installation details on temperature
compensation, refer to OPTIONS section.
2. PROTECTION REQUIREMENTS: - The unit should not be placed in direct sunlight or close to
any heat generating source to avoid extreme temperature increases. It must receive adequate
protection from rain, dust and insects. The SC1 is NOT designed to be mounted outdoors or in
high humidity environments unless protected by a suitable enclosure.
3. MOUNTING: - Secure the SC1 to the selected location using the four mounting holes on the
chassis and proper fasteners.
4. COMPLETE THE INSTALLATION OF THE PANELS, BATTERIES AND LOAD: - Follow the
manufacturer's instructions for mounting and wiring the solar panel, batteries and the load.
5. SELECT WIRE:
WIRE TYPE: - It is recommended that stranded wire rather than solid wire be used
whenever possible, because stranded wire does not fatigue and cause loose
connections over time as easily as solid wire does.
WIRE SIZE: - The SC1 terminal block accepts bare wire up to 10 AWG. (The 50 amp
model accepts up to 6 AWG). Wire should be sized of sufficient gauge to safely handle
the rated current of the system and to limit voltage drop. Consult wire sizing tables and
local alternative energy system suppliers for information on wire sizing.
6. REMOVE POWER FROM BATTERY / PANELS: - Disconnect power from the batteries and
panels prior to running the wires to the SC1 to prevent accidental damage or bodily harm.
7. SET CIRCUIT BREAKER TO “OFF”: - Make sure the load circuit breaker on the SC1 is
“OFF”.
8. RUN SYSTEM WIRING: - After disconnecting the power sources, refer to wiring diagram
(FIGURE 1) and run the system wiring to the location of the SC1. The wires should reach the
location of the SC1 with a little extra for strain relief loops.
