Voltage limits
• When mains drops below 165 VAC, the CBU supplies voltage for the emergency lighting from the
batteries
• When mains is disconnected, the CBU supplies voltage for the emergency lighting from the batteries.
• If the battery voltage rises above 28,5 V, the CBU gives a Battery Overvoltage warning
• If the battery voltage drops below 20,0 V:n, the CBU gives a Battery Undervoltage warning.
• During battery mode, if the battery voltage drops below 19,0 V:n, the CBU goes into deep discharge
mode.
