INSTALLATION WARNING
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 makers no representation or warranty as to the
merchantability, suitability or fitness of these units for any specific application.
DO NOT block any of the cooling vents on the sides and always allow adequate ventilation by not installing the unit inside tightly closed
spaces. Physical mounting position is not critical but the cooling vents must not be blocked. Make certain the input voltage switch is
set to the correct voltage BEFORE applying AC power.
The power supply output voltage measured at the rear panel terminals should be set to 56 VDC using an accurate voltmeter.
This is to compensate for the 0.3 volt drop of the diode switches. If this voltage is not correct, charger mis-operation will
result.
Connect the battery positive to the red terminal labeled, “Battery Positive (+)”.
Connect the load positive to the red terminal labeled, “Load Positive (+)”.
Connect the power supply positive output to the red terminal labeled, “Power Supply Positive (+)”.
Connect the power supply, battery and load negative outputs to the black terminal labeled, “Power Supply, Load, Battery Negative (-).
