[1] SAFETY PRECAUTIONS– Before use, read the following safety precautions.–
This instruction manual explains the current sensor CL40I0R /CL68I0R / CL110I0R for I0R700V / I0R700.
Before using, read through this manual to reduce the risk of fire ,electric shock, and/or injury. And save it together with the product sothat you can refer to the manual as necessary.
The instructions given under the headings of " WARNING" mustbe followed to prevent accidental burn and electric shock and"CAUTION" as well.

1.1. Explanation of Warning Symbols
The meanings of the symbols used in this manual and attached to theproduct are as follows.
: Extremely-important instructions for safe use
WARNING identifies conditions and actions that could result inaccidental burn and electric shock.

1.2. Warning Instructions for Safe Use
WARNING
The following instructions are intended to prevent injury such asburn and electric shock.
These instructions must be followed.
1. This instrument is for low voltage measurement. Use it withelectric paths below CAT.III 300 V.
2. Use caution when working with voltages above 33 V ac rms(46.7 V peak) or 70 V dc. These voltages pose a shock hazard.
3. Do not apply any voltage exceeding the maximum rated input
voltage (see 1.3.).
4. Do not use the instrument if the CT unit or output cable look damaged.
5. Do not use the instrument with the case opened.
6. Grab the lead wire side of the barrier of current sensor during
measurement to prevent electric shock.
7. When the current sensor is clamping a conductor, do notconnect or disconnect the output cable terminal.
8. Do not operate the instrument when it is wet or with wet hands.
9. Insulation protective equipment must be used to prevent
accidents for facilities which have dangerous live line parts.
Follow local and national safety standards.
10. Never attempt to repair or modify the instrument.
11. Use indoors.
12. Make sure that a pre-operational check is performed and an
inspection is performed at least once a year.
13. Do not use the instrument in places where explosive gas or
corrosive gas is generated.
14. Use the instrument in the specified method to prevent fromlosing the protective function.

[2] APPLICATIONS[5] MAINTENANCE

This device is a current sensor for measuring a leakage current
dedicated to the I0R logger I0R700V / I0R700.

WARNING
1. The followings are important to safety. Read this manual throughly tomaintain the instrument.
2. Calibrate and inspect the instrument at least once a year to ensure
safety and maintain its accuracy.

[3] PART IDENTIFICATION

Current direction mark5.1. Simple Examination
1) Appearance: Check that the instrument does not look damaged
caused by dropping etc.
2) The current sensor, cable and output plug: Check that anywhere isnot damaged and the cable core is not exposed from anywhere.
If you find any problem on the above items, stop using immediately
and ask us to repair it.

5.3. Storage

CAUTIONCAUTION

1- Be sure to turn off the power of I0R700 / I0R700V before
connecting the device.
2- When connecting to I0R700 / I0R700V, align the arrow markon the current sensor output terminal with ▲ mark on theinstrument.
3- Do not directly pull on the cable.
4- Do not strongly bend the cable near the output plug.
5- When disconnecting the output plug, pull on the plug lock(ring engraving), not the cable.

1. The instrument is not resistant to volatile solvents. Do not wipeout with solvents or isopropyl alcohol.
2. The instrument is not resistant to heat. Keep it away from heatgenerating devices such as solder irons.
3. Do not save the instrument into vibratory places or where theinstrument may fall off.
4. Do not expose the instrument to direct sunlight and do notsave it into any places with extreme temperature, humid, orcondensation.

Connect the output plug of this device to the I0R700 / I0R700V current
input terminal (CURRENT INPUT) to use it.
