User’s Manual
SAFETY PRECAUTIONS 
(Always read these precautions prior to use.)
Before using this product, please read this manual carefully and pay full attention to safety
to ensure that the product is used correctly.
The precautions presented in this manual are concerned with this product only. For
programmable controller system safety precautions, refer to the user’s manual of the
programmable controller to be used. In this manual, the ●SAFETY PRECAUTIONS ●
are ranked as “DANGER“ and “CAUTION“.
DANGER Indicates that incorrect handling may cause hazardous
conditions, resulting in death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous
conditions, resulting in medium or minor injury and/or
property damage.
Note that failure to observe the CAUTION level instructions may lead to a serious
consequence according to the circumstances. Always follow the precautions of both levels
because they are important to personal safety.
Please keep this manual in an easy-to-access location for future reference, and be sure to
provide the manual to the end user.

[Installation Precautions]
CAUTION
Use this module in an environment that complies with the general specifications
described in the catalog. Use in an environment outside the scope of general
specifications may result in risk of electric shock, fire, malfunction, product damage,
and deterioration.
During installation, be sure to fully secure the module using a DIN rail or mounting
screws and fully tighten the screws to the specified torque. Loosely tightened screws
results in the risk of the module dropping and malfunction.
Be careful to prevent foreign matter such as dust or wiring chips from entering the
module. Failure to do so may result in the risk of fire, failure, and malfunction.
Do not touch a powered terminal. Doing so results in the risk of malfunction.
Do not directly touch a powered section of the module. Doing so results in the risk of
module failure and malfunction.
[Wiring Precautions]
DANGER
Be sure to shut off all phases of the external power supply used by the system
before installation or wiring work. Failure to do so results in the risk of electric shock,
module failure, and malfunction.
CAUTION
Be sure to ground the FG terminal by applying class D grounding (class 3 grounding)
or higher. Failure to do so results in the risk of electric shock and malfunction.
Correctly wire cables to the module after checking the rated voltage and terminal
layout of the product. Connecting a power supply having a different rating or wiring
the module incorrectly results in the risk of fire and malfunction.
When wiring the input signal line and output signal line, do not bind the line with or
have the line contact wiring having superimposed noise. Doing so results in the risk
of malfunction.
Tighten the terminal screws within the range of the specified torque. If a screw is too
loose, a short circuit, or malfunction may result. If a screw is too tight, screw and/or
module damage may result, causing the module to drop, a short circuit, or
malfunction.

3
[Startup and Maintenance Precautions]
DANGER
Do not touch a terminal while the module is powered. Doing so results in the risk of electric
shock and malfunction.
Be sure to turn the power OFF before cleaning the module or retightening terminal screws.
Failure to do so results in the risk of module failure and malfunction.
CAUTION
Do not disassemble or modify the module. Doing so results in the risk of failure, malfunction,
injury, and fire.
Be sure to shut off all phases of the external power supply module installation or removal.
Failure to do so results in the risk of electric shock, module failure, and malfunction.
[Disposal Precautions]
DANGER
At the time of disposal, treat the product as industrial waste.

·Install the module in a location having a constant ambient temperature.
·Connect the thermocouple or compensation lead wire directly to the terminal
block.
Note 1: For the cold junction compensating resistor (RTD), connect the supplied
Q68TD-G-H01 and -H02 products to terminal numbers 38 and 40 as
illustrated above. Terminal number 38 (RTD G) and terminal number 40
(RTD -) are connected inside the conversion module, and therefore do
not require external wiring.

4. USAGE PRECAUTIONS
(1) For wiring to the terminal block, refer to the manual of the programmable controller module to be
connected, published by Mitsubishi Electric Corporation.
(2) Ground the FG wire provided with the cable in the same manner as the programmable controller
module. Note that rolling up extra wire without grounding the wire may cause the wire to function
as an antenna, resulting in the risk of noise.
