Specialty Concepts PPC - Manual (Page 6)

9. NOTE WIRE POLARITY: - Insure that the polarity of the wires is correctly marked, using
colored wires or tags. Incorrect polarity should not damage the PPC, but incorrect operation
would result.
10. COMPLETE ARRAY AND BATTERY CONNECTIONS: - Connections to the PPC terminal
block should be made with just the bare wire (not crimped spade or ring lugs unless the lugs
are crimped AND soldered)
11. COMPLETE LOAD CONNECTIONS: - Refer to wiring diagram (FIGURE 1). DC loads not
exceeding the rated PPC load current (see specification section “Load Current, Continuous”)
can be connected to the load terminals of the PPC and they will automatically be
disconnected in the event of a low-voltage condition. Higher current, or inductive loads such
as pumps, motors or inverters should be connected directly to the battery, using properly rated
over-current protection devices (fuses or circuit breakers).
12. BATTERY VOLTAGE SENSE CONNECTIONS: - The factory has installed two jumpers onto
the terminal block. They connect the "BATTERY VOLTAGE SENSE" (positive and negative)
terminal to their respective "BATTERY" terminals. These jumpers should remain in place if
the PPC is located within 5-10 feet of the batteries and if large enough wire is used to
minimize voltage drops to less than 2%.
If the PPC is at a greater distance from the batteries and/or if the voltage drop in the
battery wires exceeds 2%, then the jumpers should be removed and replaced with another
circuit running directly to the battery terminals. This is a low current, voltage sensing circuit
that can be wired in 16 AWG wire. Proper over-current protection should be added on the
positive side. This connection will allow the PPC to accurately measure battery voltage.
13. INSTALL FUSING AS NEEDED: - Add circuit protection where needed. A 30 amp fuse
(or 50 amp with P-Option) should be installed on the Battery (+) run of the PPC. Fusing is
also advised for the battery voltage sense connection, if included. The load is already
protected by the built-in circuit breaker of the PPC.
14. ATTACH TEMPERATURE COMPENSATION CABLE: - See Temperature Compensation
section
15. MAKE NEEDED ADJUSTMENTS TO SETTINGS: - See Setting/Adjustments section
16. RECONNECT BATTERY AND ARRAY POWER - Reconnect both power sources, then
position the load circuit breaker on.
