TDK Lambda | Z+Low Voltage User Manual

3.9.11 Grounding Outputs Either the positive or negative output terminals can be 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. Always use two wires to connect the load to the power supply regardless of how the system is grounded. NOTE: Models up to 100V (including) can float between outputs to ground no more than +/-100V. Models above 100V can float between outputs to ground no more than +/-600V. NOTE: According to Safety Standards, Voltage < 60V considered Non-Hazardous. Models up to 50V (including) with floating outputs to ground less than +/-60V considered as Non-Hazardous. Warning: According to Safety Standards, Voltage >60V considered Hazardous. All models include models up to 50V with floating outputs to ground more than +/-60V considered as Hazardous.

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.3-10 for sense connector location.

3.10.1 SenseWiring

WARNING: There is a potential shock hazard at the sense connector when using a power supply with an output voltage greater than 60VDC. 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.
