What is highVoltageAlarm?
This is the DC bus voltage ceiling that, once crossed, trips the plant's high-voltage alarm, per the description. A high-voltage condition on a battery-backed telecom power plant usually means a rectifier's voltage-regulation loop has failed and is overcharging the batteries, so this threshold is what separates 'still within float tolerance' from 'rectifier runaway, batteries at risk of overcharge damage.' A setting of 565 (56.5 volts) on a -48V-nominal plant would alarm well before the bus reaches levels that start stressing standard VRLA battery cells.
