For non-standard battery voltages above 80V, the jumper is set on 12 and a resistor is installed in the
charger wire harness based on the following calculation: R = 1250 x (Nominal Battery Voltage) – 15000.

For non-standard battery voltages between 12V and 80V, the jumper is set on SP and resistor R9 is
installed on the control based on the following calculation: R9 = 1250 x (Nominal Battery Voltage) –
15000.
- Jumper J4 is used to lock out several parameters in the programming mode.
Caution: Placing jumpers on any other position on J4 may damage the control and voids the warranty.
