SP PRO Interactive Inverter Charger
Technical Note

SP PRO and PL Wiring

The SP PRO Digital Control Inputs
needs to be powered, from the
battery bank is easiest.
1. Connect Battery Positive via a
suitable fuse – 100mA is sufficient -
into DGTL CTRL IN 1 POS terminal
on Expansion Card.
2. DGTL CTRL IN 1 NEG connects
through to the PL 'G' terminal.
3. For PL60 regulators, connect the
other 'G' terminal to Battery
Negative.
Main PL battery terminals are a
convenient battery positive or
negative connection point.
Note: Digital Inputs are independent current limited inputs which
are 'opto' isolated and reverse polarity protected.

Test Operation

The PL regulator can be manually moved through its charging stages. A long-push on the BATV
menu will show the current charging phase. Subsequent long-pushes will move the PL into the
next phase in the cycle.
Move the PL through to Float phase and the SP PRO will also switch to Float stage. If this
doesn't occur, check the wiring and settings in both SP PRO and PL.
Note: The SP PRO will only switch back to initial when the battery voltage falls below the Initial
Return voltage and not when the PL is moved to other charge phases.
