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 @100Volts

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.

This figure may vary slightly depending on the redundancy mechanisms incorporated, the number of device
bays occupied and the device type occupying the bays.
