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. P ower and grounding

cables are not supplied with the router. For cable specifications, see “Power,

Connection, and Cable S pecifications” 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 t he 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 p ower to the router, follow this procedure (see Figure 105):
