Connecting Power to the Router

Connect power to the router by attaching a grounding cable to the chassis grounding points and attaching power cables from external power sources to the terminal studs on the circuit breaker box. Power and grounding cables are not supplied with the router. For cable specifications, see “Power, Connection, and Cable Specifications” on page 67.

NOTE: The router must be connected to at least two separate external power sources.

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 the circuit breaker box. You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–)to indicate their polarity.

To connect power to the router, follow this procedure (see Figure 105):
