Please read these instructions before use

Model:

BMPPT1500

BASIC WIRING OPTIONS:

Permanent Load Connection
(Figure 1):

Simplest wiring option where the 
load is permanently connected 
and the batteries are not 
protected from overdischarge.

Wiring With Low Voltage 
Disconnect (Figure 2) :

This option protects the 
battery from overdischarge by 
disconnecting the load. The 
LVD option disconnects the 
load when the battery voltage 
drops below 0.85 of nominal 
voltage to protect the battery 
from damage. The load 
reconnects when the battery 
voltage exceeds 0.95 of 
nominal voltage. This feature 
will not trigger during short 
transients. LVD load is 40A 
continuous or 60A transient.
