NOTICES BEFORE REPAIRING
To make the best use of this equipment, make sure to
obey the following items when repairing (or mending).
1. Do not damage or melt the tunicate of the leading
Insulation resistance: 7.3M to 10.1 M (500 V/s)
wire on the AC1 side, including the power supply
Voltage-withstand: 3.0 kV for 1 minute

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 Safety checker (Model 7110, etc.)
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. Earth cable
5. After repairing, always measure the insulation
