Caution
For continued protection against fire hazard, you must replace the fuse
with one of the same type and rating.
Creating a Power Cable
You must create a power cable to supply power to the 9485/9487. You need the fol-
lowing materials:
•
Three-position power connector (supplied)
•
14 (1.6 mm), 16 (1.3 mm), or 18 (1.0 mm) gage solid or stranded copper wire within
a braid/foil shielded cable, rated 80° C or better
Perform the following steps to create the cable:
1.
Cut the wire cable to the desired length. It is good practice to make the protective
earth ground wire ¼-inch (6.35 mm) to ½-inch (12.7 mm) longer than the +VIN
and -VIN wires.
2.
Strip .39-inch (10 mm) of insulation from the end of the cable. 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 keeps the wire from
fraying.
Warning
When inserting the wire ends of the power cable into the block plug, be
sure that no bare wire is exposed. Trim the wire ends of the cable or cut
new cable if necessary.
4.
Insert three wire ends of the power cable into the three holes of the block plug,
as shown in Figure 2. The Ground (PE) +VIN and -VIN wires should be inserted
into the corresponding holes (again, refer to Figure 2). Be sure that no bare wires
are exposed.
5.
Tighten the three screws above the wires to hold them firmly in place.
Warning
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.
