J4350 and J6350 Services Router Getting Started Guide
CAUTION: There is no standard color coding for DC power cables. The color coding
used by the external DC power source at your site determines the color coding
for the leads on the power cables that attach to the terminal studs on each power
supply. You must ensure that power connections maintain the proper polarity. The
power source cables might be labeled
(+)
and
(–)
to indicate their polarity.
WARNING: Power plant ground and chassis ground must be connected to the
same building ground.
CAUTION: Before router installation begins, a licensed electrician must attach a
cable lug to the grounding and power cables that you supply. A cable with an
incorrectly attached lug can damage the router (for example, by causing a short
circuit).
Each DC power cable (–48 VDC and return) must be 14 AWG single-strand wire
cable, or as permitted by the local code. Each lug attached to the power cables
must be a ring-type, vinyl-insulated TV14-6R lug, or equivalent.
NOTE: Power cords and cables must not block access to router components or
drape where people might trip on them.
For information about the DC power supply, see “J4350 Power System”
on page 21 or “J6350 Power System” on page 21.
To connect the DC power cable during initial installation, see
“Connecting DC Power” on page 88.
To replace a DC power cable, see “Replacing a DC Power Supply Cable” on page 162.
