14) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
15) Design system (control panel, etc) considering the 2 seconds of delay that the controller’s output to be set
after power ON.
16) The output may turn OFF when shifting to certain levels. Take this into consideration when performing
control.
17) The number of EEPROM write operations is limited. Therefore, use RAM write mode when frequently
overwriting data during communications or other operations.
18) Always touch a grounded piece of metal before touching the Digital Temperature Controller to discharge
static electricity from your body.
19) Control output that is voltage output is not isolated from the internal circuits.When using a grounded
thermocouple,do not connect any of the control output terminals to ground. (Doing so may result in an
unwanted circuit path, causing error in the measured temperature.)
20) When replacing the body of the Digital Temperature Controller, check the condition of the terminals. If
corroded terminals are used, contact failure in the terminals may cause the temperature inside the Digital
Temperature Controller to increase, possibly resulting in fire. If the terminals are corroded, replace the
case as well.
21) Use suitable tools when taking the Digital Temperature Controller apart for disposal. Sharp parts inside the
Digital Temperature Controller may cause injury.
22) Check the orientation of the connectors on the Conversion Cable before connecting the Conversion Cable.
Do not force a connector if it does not connect smoothly. Using excessive force may damage the
connector.
23) Do not place heavy object on the Conversion Cable, bend the cable past its natural bending radius, or pull
on the cable with undue force.
24) Do not connect or disconnect the Conversion Cable while communications are in progress. Product faults
or malfunction may occur.
25) Make sure that the Conversion Cable
,
s metal components are not touching the external power terminals.
26) Do not touch the connectors on the Conversion Cable with wet hands. Electrical shock may result.

Service Life
Use the Temperature Controller within the following temperature and humidity ranges:
Temperature:
−
10 to 55
°
C (with no icing or condensation), Humidity: 25% to 85%
If the Controller is installed inside a control board, the ambient temperature must be kept to under 55
°
C,
including the temperature around the Controller.
The service life of electronic devices like Temperature Controllers is determined not only by the number
of times the relay is switched but also by the service life of internal electronic components. Component
service life is affected by the ambient temperature: the higher the temperature, the shorter the service
life and, the lower the temperature, the longer the service life. Therefore, the service life can be
extended by lowering the temperature of the Temperature Controller.
When two or more Temperature Controllers are mounted horizontally close to each other or vertically
next to one another, the internal temperature will increase due to heat radiated by the Temperature
Controllers and the service life will decrease. In such a case, use forced cooling by fans or other means
of air ventilation to cool down the Temperature Controllers. When providing forced cooling, however, be
careful not to cool down the terminals sections alone to avoid measurement errors.
O
Ambient Noise
To avoid inductive noise, keep the wiring for the Digital Temperature Controller's terminal block wiring
away from power cables carrying high voltages or large currents. Also, do not wire power lines together
with or parallel to Digital Temperature Controller wiring. Using shielded cables and using separate con-
duits or ducts is recommended.
Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors,
transformers, solenoids, magnetic coils or other equipment that have an inductance component). When
a noise filter is used at the power supply, first check the voltage or current, and attach the noise filter as
close as possible to the Temperature Controller.
Allow as much space as possible between the Digital Temperature Controller and devices that generate
powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.
