Battery Backup
12-volt DC Battery Backup terminals are provided at terminal block TB3 on the rear of the analyzer
chassis. These terminals may be connected to a fixed 12vdc power source to act as a backup in
case the main mains power has been lost. The circuit will detect loss of the mains power and the
VDC battery backup will maintain power to the system.
Connection to the Battery Backup is not required for normal operation of the analyzer. Be certain
to match the terminal pins against the terminal ID label on the top of the analyzer chassis.
