Operating Instructions
Please read these instructions before use
Basic Wiring With Permanent Load Connection:
Note:
First start up may take up to one minute.
For simplicity in the following drawings unconnected wires are not depicted.
Settings And Configurations:
The MPPT12-2P factory default setting is for sealed lead acid batteries (Maximum charge voltage 14.2V
and float voltage 13.4V) and auxiliary switch (grey wire) configured in Low Voltage Disconnect mode.
The various operating modes can be configured with a combination of the green and yellow wires and
the internal links CHE and REN.
Always ensure that the CHE link is set for the Correct Battery Type:
The yellow and green wires are either left unconnected (Ensure they are insulated from any other point),
or grounded (shorted to the black wire).
To access the CHE ( 2 pin ) and REN ( 3pin ) links carefully remove the bottom cover of the unit via the 4
x screws on the bottom of the unit.
