HE1U-1248-BBLVD Wiring Layout
This system setup will provide continuous power to the load and maintain the battery bank with smart charger while AC power
is on. There is a seamless transfer of the load to the battery when the AC power goes off. The LVD will disconnect the battery if the
voltage drops below 42 VDC. The battery reconnects once AC power is restored and voltage reaches 50 VDC.
