Electrical Considerations

Circuit Overloading

Care should be taken to ensure that the current does not exceed the rating of the power source circuitry. This includes cabling, power distribution units, filters and any other components through which the main A/C flows. The power requirements of the Voyager 3000 shelf is 1Amp @200Volts and 2A @100Volts4 and must be added to the power demands of any other electrical devices installed in the cabinet to arrive at a total power consumption figure. In addition surge currents must be catered for. Disk devices normally consume twice the amount of current at start up time as they do during steady state operation.

Grounding

Eurologic recommends that all rackmounted shelves be grounded to a common point in the cabinet in a radial topology as shown in Figure 2-1.
