WARNING

OUTPUT TERMINAL GROUNDING

There is a potential shock hazard at the RS232/RS485 and the IEEE ports when using power supplies with rated or combined voltage greater than 400V with the Positive Output of the power supplies grounded. Do not connect the Positive output to ground when using the RS232/RS485 or IEEE under the above condi- tions.

3.10 LOCAL AND REMOTE SENSING

The rear panel J2 sense connector is used to configure the power supply for local or remote sensing of the Output Voltage. Refer to Fig.3-14 for sense connector location.

3.10.1 Sense wiring

WARNING

There is a potential shock hazard at the sense connector when using a power supply with a rated Output Voltage greater than 40V. Local sense and remote sense wires should have a minimum insulation rating equivalent or greater than the maximum Output Voltage of the power supply. Ensure that the connections at the load end are shielded to prevent accidental contact with hazardous voltages.

3.10.2 Local sensing

The power supply is shipped with the rear panel J2 sense connector wired for local sensing of the Output Voltage. See Table 3-4 for J2 terminals assignment. With local sensing, the Output Voltage regulation is made at the output terminals. This method does not compensate for voltage drop on the load wires, therefore it is recommended only for low load current applications or where the load regu- lation is less critical.
