Reconnecting DC-Input Power Supply Unit

The following procedures explain how to reconnect a DC-input power to the SCE 2000 platform.
Warning
Before completing any of the following steps, and to prevent short-circuit or shock hazards, ensure that
power is removed from the DC circuit. To ensure that all power to the power supply unit is OFF, locate
the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF
position, and tape the switch handle of the circuit breaker in the OFF position.
Note that the power to the relevant power supply unit should be off, not necessarily all power to the
SCE 2000 platform. One DC-input power supply can be running when the other power supply is being
removed or replaced.
Wiring should be done by a professional in accordance with state and local electrical codes.
