Specialty Concepts PPC - Manual (Page 5)

INSTALLATION INSTRUCTIONS:
1. LOCATION: - A suitable location must be found for mounting the PPC. 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. The temperature sensor wire is 10 feet long and should reach the
battery bank if possible.
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 standard PPC is supplied in an indoor NEMA 13
enclosure, or an optional outdoor enclosure is available.
3. MOUNT THE PPC ENCLOSURE: - Remove the inner panel of the PPC by unscrewing the four
acorn nuts in the four corners. Determine the size and location of holes needed in the
enclosure for conduit hubs or strain relief feed-throughs for the wiring. Proceed with making
holes in the steel NEMA 13 enclosure or the plastic NEMA 4X enclosure. Then clean out any
debris and replace the internal panel.
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 standard PPC 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 PPC to prevent accidental damage or bodily harm.
7. SET CIRCUIT BREAKER TO “OFF”: - Make sure the load circuit breaker on the PPC 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 PPC. The wires should reach the
location of the PPC with a little extra for strain relief loops.
