1.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 SN4400—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.

An approved power supply that incorporates a disconnect device must be used and positioned within easy reach of the operator’s position.

CAUTION

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.

6.Verify that the green POWER LED is lit.

Hardware installation is complete. Refer to chapter 4, “Getting started with the SmartNode 4400 Series” on page 34.
