Completely install all BDM-300X2 and all system inter-wiring connec
�
ons prior to
installing the PV modules.
1. Mount the PV modules above their corresponding BDM-300X2. Each BDM-300X2
comes with two oppositely sexed DC connectors.
2. First connect the posi
�v
e DC wire from the PV module to the nega
�
vely marked
DC connector (male pin) of the BDM-300X2. Then connect the nega
�
ve DC wire
from the PV module to the positively marked DC connector (female socket) of the
BDM-300X2. Repeat for all remaining PV modules using one BDM-300X2 for each
module.
