You must supply the DC power cables that meet the specifications in
or as required by the local code, laws, and standards.

WARNING: For field-wiring connections, use copper conductors only.
CAUTION: Before TCX1000-RDM20 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 TCX1000-RDM20.
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 terminals
on each power supply.
