5.1
Low Voltage Disconnect: The ULM-100 incorporates a 100 Amp solid state LVD circuit which automatically removes
the battery when battery voltage drops to a pre-set DISCONNECT threshold (or when manually activated- see section
5.11) and automatically re-connects the battery when battery voltage rises above the selected CONNECT threshold (see
Specification 8.0 for default LVD thresholds and adjustment ranges)
