18 Cisco 3600 Series Power Supply Conﬁguration Note

Replacing Connections to the Router

If you have a DC-powered router, rewire the DC-input power supply (38 to 72 VDC) to

the terminal block using 14 AWG copper wires. The proper wiring sequence is ground to

ground, positive to positive, and negative to negative. (See Figure 20 and Figure 21.)

Warning This product relies on the building’s installation for short-circuit (overcurrent) protection.

Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international)

is used on the phase conductors (all current-carrying conductors). (To see translated versions of this

warning, refer to the Regulatory Compliance and Safety Information document that accompanied the

router.)

Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop

or spade-type with upturned lugs. These terminations should be the appropriate size for the wires

and should clamp both the insulation and conductor. (To see translated versions of this warning, refer

to the Regulatory Compliance and Safety Information document that accompanied the router.)

Warning The illustration shows the DC power supply terminal block. Wire the DC power supply

using the appropriate lugs at the wiring end, as illustrated. The proper wiring sequence is ground to

ground, positive to positive (line to L), and negative to negative (neutral to N). Note that the ground

wire should always be connected ﬁrst and disconnected last. (To see translated versions of this

warning, refer to the Regulatory Compliance and Safety Information document that accompanied the

router.)

Caution Do not overtorque the terminal block captive thumbscrew or terminal block contact

screws. The recommended torque is 8.2 ± 0.4 inch-lb.

Warning After wiring the DC power supply, remove the tape from the circuit breaker switch

handle and reinstate power by moving the handle of the circuit breaker to the ON position. (To see

translated versions of this warning, refer to the Regulatory Compliance and Safety Information

document that accompanied the router.)
