Page 18: Load Considerations
Load Considerations Note that the output will become unstable if the following types of loads are connected. Loads with peak current or pulse-shaped current The PWR-01 only indicates mean values. Even when the indicated value is less than or equal to the set constant current, the peak values may exceed the set constant current.
Page 19 Installation and Preparation ｜ Load Considerations Loads with accumulated energy Connecting a load with accumulated energy, such as a battery, to the PWR-01 may cause current to flow from the load to the internal circuit of the PWR-01. This current may damage the PWR-01 or reduce the life of the load.
Page 20: Selecting The Load Cables
+ (positive) and - (negative) output wires of the load cable side by side or bundling them together is more effective against unwanted noise. The Kikusui-recommended currents shown in the above table are allowable currents that have been reduced in consideration of the potential bundling of load cables.
Page 21 Installation and Preparation ｜ Selecting the Load Cables  Limitations of the remote sensing function All wires have resistance. As the wire becomes longer or the current becomes larger, the volt- age drop in the wire becomes greater. This results in a smaller voltage being applied at the load end.
Page 22: Output Terminal Insulation
Output Terminal Insulation Risk of electric shock. For safety reasons, even if the output terminal is grounded, WARNING make sure that the insulation capacity of the output terminal (including the sensing terminal) is greater than or equal to the isolation voltage of this product. For details on the isolation voltage of each model, see "Specifications"...
Page 23: When The Output Terminal Is Grounded
Installation and Preparation ｜ Output Terminal Insulation When the output terminal is grounded If the positive output terminal is connected to the chassis terminal, the positive output termi- nal is at ground potential. The cable and load that are connected to the output terminal (including the sensing terminal) will only require an insulation capacity that is greater than or equal to the maximum output voltage of the PWR-01 with respect to the chassis.
Page 24: Connecting To The Output Terminals
Connecting to the Output Terminals Risk of electric shock. WARNING • Turn the POWER switch off before you touch the rear-panel output terminals. • Even if you turn the output off or turn the POWER switch off, if the bleeder circuit is set to off (CF01: DIS), the voltage that was present when the output was on will remain at the output terminals.
Page 25 Installation and Preparation ｜ Connecting to the Output Terminals Connect the load cables to the rear-panel output terminals. Use the included screw set. Memo To reduce the influence of noise on the output, keep the cables as short as possible. If If you do not connect load possible, twist the positive and negative load cables.

Parallel/ Series Operation ｜ Master-Slave Parallel Operation Starting master-slave parallel operation Turning on the POWER switch Turn on the master unit’s POWER switch. Turn off the POWER switch of each slave unit. Operate the master unit normally. You cannot perform panel operations on the slave units. Turn output on and off from the master unit.
Page 108: Series Operation
Series operation Series operation is not possible on the H type (PWR401H, PWR801H, PWR1201H). If WARNING you do, the output will exceed the isolation voltage resulting in a dangerous condi- tion. Up to two PWR-01s whose output is less than 650 V can be connected in series. You cannot perform master-slave series operation.
Page 109 Parallel/ Series Operation ｜ Series operation Remote sensing • If the sensing cables are not connected properly, the load may be exposed to excessive CAUTION voltage, and the PWR-01s may be damaged. • To prevent oscillation, connect an electrolytic capacitor with a capacitance of a few hundred µF to a few ten thousand µF across the load as necessary.
