2.3.2 Connecting the insulator to your power sources
There are three male contact pins, three female contact pins and a pair
of insulators in the accessory box. The installation procedure is
described as follows:
STEP 1. Connect the three contact pins individually to the negative
and positive power cables of the power adaptor, as well as to the frame
ground cable. Solder firmly.
STEP 2. Align the soldered pins and their cables with the correspond-
ing polarization marks on the front part of the male insulator (+ / G / -).
Now plug the pins separately into the holes of the male insulator. Pin 1
should go into the positive DC power input ( + ), pin 2 connects to the
frame ground ( G ), and pin 3 should be plugged into the negative DC
power input ( - ).
