Caution for Safety
WARNING
1.power
1) use it within rated voltage in order to protect equipment and prevent and
prevent trouble.
2) ln order to prevent electric shock and equipment damage when installing
equipment check wiring after finishing wiring and than input power.
3) use standard wiring and terminal for connecting power .this can cause
electric shock and fire.
2.caution for operation
1) lf abnormality of this equipment is related to serious accident, it is
recommended to install protection device in addition.
2) Do not use this equipment in the gas (This is not explosion-proof structure).
If this equipment is exposed to gas do not operate power switch and
so on but operate ane it when it is sage after venting the space.
3) Do not use in the place with chemical materials, There is danger of electric
leakage and electric shock.
4) Do not touch or loosen terminal when there is applied lt can cause electric
shock or mal -operation.
5) Do not touch the product when there is water around or when body is wet.
There is danger of electric shock.
6) Do not install the equipment in the place where children can touch the
equipment.
3. Caution for wiring and maintenance
1) Perform wiring for this equipment exactly into relevant number as show in
the instruction manual or terminal instruction. (Tighten terminal bolt firmly)
mal-wiring can cause equipment damage, mal- operation of fire .
2) Perform repair or assembling after turning off external power switch and
interrupting external circuit power. It can cause electric shock or trouble.
3) Never disassemble reform or repair equipment lt cause electric shock fire
product damage mal-operation or trouble.
Caution for safety, aims at securing safety of user and preventing accident
or danger in advance by using it safely ,so read and follow it well.
Caution matters are divided into ‘warning’ and ‘caution’ whose meanings
are as follows
Violating instruction may cause injury product
damage or material loss.
CAUTION
WARNING Violating instruction may cause serious damage or
death

CAUTION
1.caution for attachment and wiring
1) Fix the equipment firmly with the fixing device (included during shipment
below and above the equipment when attaching equipment.
2) lf there is severe induction noise in the power ,it is recommended to us
insulation transformer and noise removal circuit.
3) Twisted wiring of power line is effective for noise
4) lf water enters receive checking by all means.
5) Use lead wire which has low resistance is non-combustible.
6) Use output and input signal lines by separation them by all means. Use
shield wire for input signal wire and be away from load or high voltage.
7) Use sensor of non-grounding type.
2.Caution for handling
1) when operation output relay frequently by connecting load without
allowance in rating, relay life can be shorter rating so use it by adding
to outside. *Electric life of relay --About 100.000 times (under rated load)
2) Make each setting exactly and check abnormality in input and output,
3) lf sensor is single or short it is displayed “---”.
turn off voltage by all means when replacing sensor at this time .
It can cause trouble and mal -operation
4) Do not drop this product nor give shock this product. It can cause trouble
or mal-operation
5) Do not wipe the product with organic
solvent lt can cause damage in appearance .
6) Avoid use in the following condition.
: ln the place where surrounding temperature and humidity exceed the
temperature and humidity scope in usage condition.
: ln the place exposed to combustible gas or corrosive gas.
: ln the place where there is much oil water steam iron or salt.
: ln the place which is not waterproof structure exposed to outside water
or rain.
: ln the place directly exposed to direct sunshine.
: ln the place where freezing phenomenon takes due to severe
change of temperature and humidity.
relay
4) Replace sensor after turning off power by all means. Lt can cause electric
shock.
Fire product damage mal-operation or trouble.
5) The components of this equipment have life period and include year -passing
components There is 1 year of guarantee period from purchasing date.
However. Trouble due to customer mistake and natural disaster is excluded.

Power input is free voltage (DC 48V) and it is stably
operated even at bad condition such as outside power change,surge etc
Temperature of transformer is measured and displayed and
alarm output (alarm, trip) and fan is controlled according to
temperature.
Temp max function -lt is possible to check the highest
temperature of transformer during operation up to now.
Data storage function memorizes T .MAX value and each control
temperature setting values.(Semieternal) T.MAX value is stored
even after turning power it is reset during operation
Each setting value is also stored after turning off power unless
setting value is changed during operation
.
.
Fan out function -lt is possible to control outside fan by
comparing fan on and fan off setting values and measured
temperature.
