Connect the earth ground of the DC source to the grounding stud on the DACS as described in the previ-
ous section entitled “Grounding the Model SN4300—AC and DC units.”
2.
Strip back the insulation on each of the wires approximately 1/4-inch.
3.
Insert the stripped end of the positive lead into the
+DC input
of the terminal block. Tighten the screw
until the power lead is firmly fastened. Repeat the procedure for the negative lead, using the
-DC input
of
the terminal block. Make sure that all strands of the wire are captured and that there are no exposed wires.
4.
Repeat steps 1 through 3 to install the remaining DC power connection.
CAUTION
An approved power supply that incorporates a disconnect
device must be used and positioned within easy reach of the
operator’s position.
5.
Connect the equipment to a 36–72 VDC, 2.5A supply source that is electrically isolated from the AC
source. The 36–72 VDC source is to be reliably connected to earth ground.
