screws on each side of the plug. This strain relief is mandatory for hazardous
locations compliance.
Warning
Completely loosen the two securing screws on the plug when
disconnecting the power cord from the unit.
DC Power Cable
You must create a DC power cable to supply power to units with DC power supplies.
You will need the following materials:
•
A three-position power connector (supplied)
•
A braid/foil shielded power cable with three 18 (1.0 mm), 16 (1.3 mm), or 14
(1.6 mm) AWG solid or stranded copper wire, rated 80º C or better.
Perform the following steps to create the DC power cable:
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.
Warning
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 3-17. Be sure that no bare wires
are exposed.
