Keep the instruction manual in a safe, convenient location for future reference.
All or part of the contents described in this manual may be changed without any notice.
Due to our constant striving for further improvement of products, parts or products that differ from those
described in this manual may be substituted.
WARNING
(Failure to observe this WARNING may cause a fatal or serious injury.)
Be sure to confirm that any peripheral equipment does not move before installation work.
In addition, observe safety requirements for installation work where high-place work is expected.
Be sure to turn off the power source before wiring, mounting and transportation work. (Failure to observe
this WARNING may result in an electric shock/ injury or equipment damage due to short-circuit.)
Carry out wiring work correctly with reference to a proper drawing.
Never disassemble the equipment. (Failure to observe this WARNING may result in an electric shock.)
Do not open the cover under an explosive environmental condition when power is entered. (Failure to
observe this WARNING may result in an injury or equipment damage.)
Do not place or store the equipment in any hostile environmental place where it will be subjected to direct
sunlight, rain, water droplet, hazardous gas/water, etc..
CAUTION
(Failure to observe this CAUTION may cause a moderate injury or equipment damage.)
Do not use the equipment for any purpose other than the original purpose of use.
Be sure to confirm the specification of equipment and use the equipment within the range of specification.
(Mounting conditions such as temperature, power source, frequency, etc.)
Make sure a correct wiring before applying power source.
Do not have a shock or strong impact to the equipment.
(Failure to observe this CAUTION may result in equipment damage.)
Be sure to connect necessary terminals (grounding, etc.).
Remove all wiring to the equipment before doing electrical welding work near the equipment.
Do not forcedly bend or pull the lead wire also do not use unnecessarily long wire.
Tighten the cover, lead outlet, etc. properly so that dust, rainwater, etc. do not enter inside the equipment.
Do not use the equipment under a corrosive condition (NH
3
, SO
2
, CI
2
, etc.).
Be sure to tighten the cable grand so that outer air does not enter inside the equipment.
When applying piping connection such as conduit, etc. instead of cable grand, apply putty or equivalents
on the cable entry so that outer air does not enter inside the equipment.
●
Do not directly touch the probe with hands regardless of power ON or OFF.
If you unavoidably have to touch the probe with hands when installation or maintenance process, be sure
to turn OFF the power and use non-conductive gloves such as rubber gloves during the process.
*Touching the probe with hand directly may cause a failure due to static electricity charge in a human body.
●
MAINTENANCE: When you clean the probe, be sure to turn OFF the power, put on non-conductive
gloves such as rubber gloves to clean the probe with moist cloth.*Touching the probe with hand directly
may cause a failure due to static electricity charge in a human body.Cleaning the probe with dry cloth may
also cause a failure due to friction charge generated between the cloth and probe.
IMPORTANT
(indicates notes or information to help customers.)
