DC Power Input for DC-Input Power Supply Cage
A DC power terminal block is provided at the rear of the DC-input power supply cage.
The terminal block will accept standard terminal lugs, size Newark* stock # 81N1501 type
CRS-T0-1406-HT. These lugs accept 14 AWG wire gauge. The width (W in Figure 40) of the lug
can be no larger than 0.25 inches.
The DC-input connector has two sets of screw terminals. Both sets of terminals should be wired
using 14AWG wire. Each terminal input should be fused with a maximum of a 10A fuse.

1. Place a #8-32 nut on the chassis stud and tighten to 10 in-lb.
2. Place the earth ground wire terminal lug on the chassis stud.
3. Place another #8-32 nut on the chassis stud so that the earth ground wire terminal is between the
