GENERAL APPLICATION NOTES and WARNINGS

WARNING: THERE ARE NO USER SERVICEABLE PARTS INSIDE. HAZARDOUS VOLTAGES EXIST INSIDE THE UNIT.
SERVICE AND REPAIR MUST BE REFERRED TO QUALIFIED FACTORY PERSONNEL.

NOTE: The individual user should take care to determine, prior to use or installation, whether this device is suitable, adequate or safe

for the use intended. Since individual applications are subject to great variation, DuraComm makes no representation or warranty as to
the merchantability, suitability or fitness of these units for any specific application.

NOTE: The LVD-24 is pre-set to disconnect the load at 21.5 VDC. However, to prevent premature or false disconnect when the battery
voltage drops below the 21.5-volt threshold a 2-minute timer is started. If the battery recovers to above 21.5 volts, the timer resets and
waits. The battery can and will recover if the system is a repeater or remote base station or similar equipment that has a varying
demand that fluctuates from low to high current. The 2-minute delay ensures the battery is not disconnected until necessary to prevent
damage.

After the AC main power is restored and the battery is recharging, the LVD-24 will reconnect the load when the battery voltage exceeds

25.0 volts.
