The AC power ground is through the power cord. The power cord
must be plugged into both the chassis and the power source for proper
grounding.
Proper grounding is required for safe operation.
It is also required to meet EMC emission and susceptibility requirements.
Power All equipment related to the chassis should be connected on the same
fused power circuit.
• The power supply can accept single-phase voltages within 90–264
V AC at frequencies between
47–63 Hz.
• The maximum continuous power usage is approximately 300 W.
The current draw depends on the local voltage supply. A 15 amp
line will be adequate for the chassis and the computer.
