Do not damage or melt the tunicate of the leading wire on the AC1 side, including the power supply cord. 2. Do not soil or stain the letters on the spec. inscription plates, notice labels, fuse labels, etc. 3. When repairing the part extracted from the conducted side of the board pattern, fix it firmly with applying bond to the pattern and the part. 4. Restore the following items after repairing. 1) Conditions of soldering of the wires (especially, the distance on the AC1 side). 2) Conditions of wiring, bundling of wires, etc. 3) Types of the wries. 4) Attachment conditions of all types of the insulation. 5. After repairing, always measure the insulation resistance and perform the voltage-withstand test (See Fig-1). 1) The insulation resistance must be 7 to 9.5 M when applying 500V per second. 2) In the voltage withstand test, apply 3 kV for 1 minute and check that the GO lamp lights. * * * * Breaking current set to 6 mA. Connect the safety checker as shown in Fig-1, then measure the resistance and perform the test. Do not touch the equipment during testing. For details of the safety checker, refer to the supplied Operation manual. Insulation resistance: 7 to 9.5 M (500 V/s) Voltage-withstand: 3 kV for 1 minute Safety checker (Model 7110, etc.) Earth cable AC cable Connect the earth cable to the outside metal part terminal.
