Connecting a CSS 11503 DC Power Cord

Before you install a DC power cord, refer to Appendix A, Specifications, for the DC power supply.

Warning The DC power supply cord requires at least a 14 AWG wire (maximum 10 AWG wire). The CSS 11503 draws a maximum of 10 amps.

Warning Use copper conductors only.

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Warning Before performing the DC installation procedure, ensure that power is removed from the DC circuit. To ensure that all power is off, locate the circuit breaker that services the DC circuit and switch it off.

Warning When you are installing or replacing the unit, the ground connection must always be made first and disconnected last.

Warning Only a DC power source that is isolated from AC mains with reinforced insulation, and that complies with the other safety extra-low voltage (SELV) requirements in UL1950, CSA 950 3rd Edition, EN 60950, and IEC950, can be connected to a Cisco 11503 system. This requirement ensures that in a catastrophic power source fault condition, hazardous voltages are not present on power terminals and connectors.
