Parallel Connections

Grounding the Output

 

The output of the power supply is isolated from earth ground. Either

 

positive or negative voltages can be obtained from the output by

 

grounding (or "commoning") one of the output terminals. Always use

 

two wires to connect the load to the output regardless of where or

 

how the system is grounded.

 

To avoid noise problems caused by common-mode current flowing

 

from the load to ground, it is recommended to ground the output

 

terminal as close as possible to the power supply chassis ground.

 

SHOCK HAZARD For models up to 60VDC rated output, no point shall be more

WARNING

 

than +/-60VDC above/below chassis ground. For models > 60VDC rated

 

output, no point shall be more than +/-600VDC above/below chassis ground.

 

There is also a potential shock hazard at the IEEE/LAN/USB ports when

 

using power supplies with rated or combined voltages > 400VDC with the

 

positive output of the power supplies grounded. Do not connect the positive

 

output to ground when using the IEEE/LAN/USB under the above conditions.

 

 

Parallel Connections

 

Only power supplies that have equivalent voltage and current ratings can be

CAUTION

 

connected in parallel.

 

 

 

Up to four units of the same voltage and current rating can be

 

connected in parallel to provide up to four times the output current

 

capability. Refer to the following figures for typical connections of

 

parallel power supplies using either local or remote sensing. The

 

figures show two units, however, the same connection method

 

applies for up to four units.
