AC Power and Grounding Requirements
The DK14 requires a solid earth ground
for proper operation. The AC power cord
contains a conductor for the “third-wire
ground” provided by the commercial
power outlet.
The third-wire ground should be the only
ground necessary for the DK14; this
ground must originate at the buildings
main power distribution panel and have a
solid connection to earth ground. (See
.)
AC Voltage Range:
♦
115VAC ± 10VAC
♦
0.7 amp. max
CAUTION!
Lack of proper ground may cause improper operation and, in extreme cases,
system failure.
