Connecting a CSS 11503 DC Power Cord
Before you install a DC power cord, refer to Appendix A, 
, 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.
