CONNECTED IN SERIES PRIOR TO THE
INSTALLATION OF THE DCX UNIT FOR SAFETY
PURPOSES. DISCONNECT SEVERAL SERIES BUS
CONNECTIONS OF THE STRING TO ENSURE THE
TOP NEGATIVE TERMINAL IS NOT CONNECTED
TO THE REST OF THE STRING SO THAT THE
INSTALLATION WORK CAN BE DONE SAFELY
WITHOUT VOLTAGE PRESENT. ENSURE THAT
ALL THE PLASTIC CELL TERMINAL COVERS ARE
INSTALLED TO PREVENT ACCIDENTAL CONTACT OR
SHORT CIRCUIT OF THE STRING TERMINALS WITH
TOOLS ETC. DURING THIS INSTALLATION PROCESS.
CAUTION!
The DCX unit ships without the battery termination bus installed and
will require assembly. The termination bus hardware comes pre-
installed on the DCX and requires removal before terminal plate can
be installed. Follow the steps below for termination bus installation
