DC-Powered Systems
Basic guidelines for DC-powered systems include the following:
Each chassis power supply should have its own dedicated input power source. The source must
comply with the safety extra-low voltage (SELV) requirements in the UL 60950, CSA 60950, EN
60950, and IEC 60950 standards.
The DC supplies each have the provision for a dual connection to the power source in order to permit
high-power operation without exceeding current ratings. For the SCE8000, it is not necessary to
connect both of these inputs to DC power sources; it is sufficient to connect only the '1' connections.
Each circuit must be protected by a dedicated two-pole circuit breaker. The circuit breaker should
be sized according to the power supply input rating and local or national code requirements.
The circuit breaker is considered the disconnect device and should be easily accessible.
The system ground is the power supply and chassis ground.
Caution Do not connect the DC-return wire to the system frame or to the system grounding equipment.
