A 3-pin Eurostyle 39860 male right-angle jack (Molex # 39860-0703) with a flame retardant wire
harness is provided for making the -48VDC power connection. Two #18 AWG wires in the harness
provide the DC power and one green wire provides the chassis ground connection. (PN: W4002)
The Frame Ground screw connection on the rear panel
must
be used in order to comply with
installation requirements. This #8-32 machine screw has two external tooth lock washers to secure the
unit rear plate Frame Ground connection to the Central Office GND system.
The terminal lug of the green wire ground wire must be placed between the star-washers to assure an
adequate connection. A
#14 AWG
or larger copper wire must be used; its length should be minimized
to assure effectiveness for controlling ESD and EMI.
