Page 7: Battery Backup Module
If your PPS-2RM-B1 includes the battery backup module, this module will allow the PPS-2RM-B1 instrument to be powered by a 24 VDC power source in case of loss of the main AC power. The switch from AC to DC supply operation is affected by a Schottky diode network and charge storage capacitors to ensure glitch free operation. - Page 8 Pin 2 GND (Internal supply voltage for monitoring purpose do not use !)
