HE1U-5012-BC-MU Wiring Layout
This system setup will provide continuous power to the load and maintain the battery bank with a float charge circuit 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 10.5 VDC. The battery reconnects once AC power is restored and voltage reaches 12.5 VDC.
