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.
RU2-3012-UPS wiring layout
This system setup will provide continuous power to the load while AC power is on. There is a seamless transfer of the load to the battery when the AC
power goes off. The LVD will disconnect the battery if the voltage drops below 11.5 VDC. The battery reconnects once AC power is restored and voltage
reaches 12.5 VDC.

CONDUCTOR PRETREATMENT
All kinds of copper conductors can be clamped without treatment. DO NOT solder tin stranded conductors. The solder yields and fractures under high
pressure. The result is increased contact resistance and excessive temperature rise. Additionally, corrosion has been observed due to the fluxes. Notch
fractures at the transition from the rigid tinned part to the flexible conductors are also possible. Ferrules can be used as a protection when wiring
stranded conductors. Copper ferrules prevent the current transfer from being influenced by dissimilar metals and remove the risk of corrosion. Always
use the correct tool to crimp the ferrule.
LIMITED WARRANTY
DuraComm warrants to the initial end user, each power supply manufactured by DuraComm to be free from defects in material and workmanship when
in normal use and service for a period of two years from the date of purchase from an authorized DuraComm dealer.
Should a product manufactured by DuraComm fail or malfunction due to manufacturing defect, or faulty component, DuraComm, at its option, will repair
or replace the faulty product or parts thereof, which, after examination by DuraComm, prove to be defective or not operational according to specifications
