code.
CAUTION: You must ensure that power connections maintain the proper
polarity. The power source cables might be labeled
their polarity. 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.
CAUTION: Power cables must not block access to TX Matrix Plus components
or drape where people could trip on them.
The accessory box shipped with the TX Matrix Plus router includes the cable lugs that
attach to the terminal studs of each power supply (see Figure 145 on page 440). (The
cable lug shown in Figure 145 on page 440 is also used for the grounding the chassis.)
CAUTION: Before TX Matrix Plus router installation begins, a licensed
electrician must attach a cable lug to the power cables that you supply. A
cable with an incorrectly attached lug can damage the TX Matrix Plus router.
