1. Cut the wire cable to the desired length.
2. Strip 0.25-inch (6 mm) of insulation from the end of the conductor wire. No bare
wire should be exposed when the cable is connected to the workstation.
3. Tin the wire ends with solder if using stranded wire. This will keep the wire from
fraying.
When inserting the wire ends of the power cable into the block plug, be
sure there is no exposed wire. Trim the wire ends of the cable or cut a
new cable if necessary.
4. Insert the three wire ends of the power cable into the three holes of the block plug.
Insert the Protective Earth GND ground, + (positive), and - (return) wires into the
corresponding holes, as shown in Figure 3-22. Be sure that no bare wires are ex-
posed.
5. Tighten the three screws above the wires to hold them firmly in place.
Never tighten the three screws of the block plug when the cable is con-
nected to a power source. The screws are conductive and have full con-
tact with the cable wire.
6. Use the aluminum cable clamp (provided) to terminate the DC cable shield and pro-
vide strain relief. The aluminum cable clamp is designed to accommodate cable with
¼-inch (6.4 mm) O.D.
7. The DC cable shield must be terminated to chassis ground (PE) at the 3408 end. A
pigtail termination will not provide enough EMI suppression in those installations
where the DC cable exits a metal enclosure.
To terminate the braided cable shield, the braid must be dressed back over the cable
insulation 1/2 inch (13 mm). The aluminum clamp must then be placed over the
braid/insulation. Use the #6-32 screw (provided) to secure the clamp to the chassis in
