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 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. Failures require
investigation as to cause and/or repair of the unit.
INSTALLER NOTES
NOTE:
The outputs are NOT referenced to the chassis. The Modular System can be used either positive or negative ground.
NOTE: DO NOT
block any of the cooling vents on the sides or top and always allow adequate ventilation by not installing the unit
inside tightly closed spaces. Physical mounting position is not critical but the cooling vents and the internal thermostatically controlled
cooling fans must not be blocked.
WARNING:
Be certain to locate the battery in a well ventilated area. During recharging, small amounts of hydrogen gas may be
produced. Hydrogen gas is highly flammable and under the right conditions, explosive.
