J4350 and J6350 Services Router Getting Started Guide

CAUTION: Th ere is no standard color coding for DC power cables. The color coding

used by the exte

rnal DC power source at your site dete rmines the color coding

for the leads on the power cables that a ttach to the terminal studs on each power

supply. You m u st ensure that power connections ma in tain the proper polarity. The

power source c

ables might be labeled

(+) and (–) to indi cate their polarity.

WARNING: Power plant ground and chassis ground must be connected to the

same b uilding ground.

CAUTION: Befo

re router installation begins, a licensed elec tricia n 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 p ower c

able (–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-ty pe, vinyl-insulated TV14-6R lug, or equivalent.

NOTE: Power co

rds and cables must not block access to router components or

drape where people mig ht trip on them.
