Notes
1. Suffix # indicates DC standby version.
2. With AC in, unit provides power to the load and to charge the
battery. The DC OK signal acts by sensing a voltage on +V and
holds the relay closed.
3. With loss of AC in, battery voltage is present on +V. DC OK
signal holds the relay closed. Battery supplies power to the load.
4. As the battery discharges, its voltage falls. When this falls below
the level shown in the table the DC OK signal switches off to
allow the relay to open to disconnect and protect the battery.
