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 BMPPT-150 factory default setting is for sealed lead acid batteries (Maximum charge voltage 28.4V 
and float voltage 27V) 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 rear plastic cover.

CHE: 

Linked - Vented Batteries, Unlinked - Sealed Batteries

REN: 

Right Link - 6 Hour DDS,  Left Link - All Night DDS, No Link - LVD   

Green Wire: 

Grounded - Enable Remote Load Control & Disable DDS & LVD,

                    

 :

 Floating - Disable RLC & Enable DDS & LVD.

Yellow Wire: 

Grounded (Green Wire Grounded) - Load Disconnected, Floating - Load Connected.

                     

 

 Note: If the Green wire is floating, the yellow wire has no effect.
