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 PDM.
WARNING: For field-wiring connections, use copper conductors only.
CAUTION: Power cords and cables must not block access to device
components or drape where people could trip on them.
