Page 20: Single Load Connection, Remote Sensing
3.7.4 Single load connection, Remote Sensing Remote Sensing is used in cases where, in Constant Voltage mode the load regulation is important at the load terminals. Use twisted or shielded wires to minimize noise pick-up. If shielded wires are used, the shield should be connected to the ground at one point, either the power supply chassis or the load ground. -
Page 21: Grounding Outputs
3.7.6 Multiple load connections with distribution terminals If remotely located output distribution terminals are used, the power supply output terminals should be connected to the distribution terminals by a pair of twisted or shielded wires.

Page 40: Series Operation
4.4.14 Series Operation 1. GENERAL: Two power supplies of the same rating can be connected in series to increase the output voltage or to provide bipolar output voltage. CAUTION When two power supplies are connected in series, they should be programmed to the same output voltage to prevent damage to the lower voltage supply at short circuit condition. - Page 41 3. Series connection for bipolar output voltage: 3.1 General: At this operation mode, two units are configured as a bipolar voltage/current source. Set the current limits of each power supply to the maximum that the load can handle without damage. It is recommended to connect diodes in parallel to each unit output to prevent reverse voltage during start- up condition or in case one of the units shuts down.

Page 42: Output Good Signal
4.4.15 Output Good Signal Output Good Signal is an open collector output, referenced to COM potential, indicating the status of the power supply output. While the power supply operates normally, the Output Good is low (0~0.8V). When the power supply output is disabled due to activated OVP, OTP or FOLD protection, or by OUT set to off, or by ac ON/OFF set to off, then the output signal stops conducting. -
