SECTION II - INSTALLATION AND WIRING Physical Installation The DF2000 indicator can be located wherever convenient. It is not advisable to locate the indicator where it would be exposed to direct sunlight, excessive mechanical abuse or moisture. Power Requirements The DF2000 desk-top model has a self-contained DC power supply that requires only a source of 115V-120V AC. If you are using your own power supply, please note that the indicator requires a 12 VDC input. It will operate satisfactorily over an input range from 11 VDC to 17 VDC. Although the indicator has built-in voltage regulation, it is most desirable that the input voltage be stable over the stated input range. Ensure that an inline fuse is installed and is of the correct size - AGCI (1 amp fast blowing). No other fuse should be used. (page 3-57)
