WARNINGS
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.
The precision regulated power supplies operate internally from voltages in excess of 12/24/48 volts. In rare cases, voltage spikes or transients on the
AC power line, or over heating, may cause a component failure in the power supply. Overloading the output will cause the over current feature to
operate. In either case, the cause must be determined and corrected.
