IM 01C50C05-01EN
2.3 Storage
When an extended storage period is expected, observe the following
precautions:
1. If at all possible, store the transmitter in factory shipped condition, that is,
in the original shipping container.
2. Choose a storage location that satises the following requirements.
• A location that is not exposed to rain or water.
• A location that is not exposed to direct sunlight.
• A location subject to a minimum of vibration or impact.
• The following temperature and humidity range is recommended.
Ordinary temperature and humidity (25°C, 65%) are preferable.
Temperature: -40 to 85°C
Humidity: 0 to 95% RH (Non-Condensation)
2.4 ChoosingtheInstallationLocation
Although the temperature transmitter is designed to operate in a
vigorous environment, to maintain stability and accuracy, the following is
recommended:
(1) Ambient Temperature
It is preferable to not to expose the instrument to extreme temperatures
or temperature uctuations. If the instrument is exposed to radiation
heat a thermal protection system and appropriate ventilation is
recommended.
(2) Environmental Requirements
Do not allow the instrument to be installed in a location that is exposed
to corrosive atmospheric conditions. When using the instrument in a
corrosive environment, ensure the location is well ventilated. The unit
and its wiring should be protected from exposure to rainwater and direct
sunlight.
(3) Impact and Vibration
It is recommended that the instrument be installed in a location that is
subject to a minimum amount of impact and vibration.

2-4
IM 01C50C05-01EN
2.5 UseofaTransceiver
Although the temperature transmitter is designed to resist inuence from high
frequency noise; use of a transceiver in the vicinity of installation may cause
problems. Installing the transmitter in an area free from high frequency noise
(RFI) is recommended.
2.6 WithstandVoltageTest
CAUTION
• Overvoltage of the test voltage that is so small that it does not cause
an dielectric breakdown may in fact deteriorate insulation and lower
the safety performance; to prevent this it is recommended that the
amount of testing be kept to a minimum.
• The voltage for the withstand voltage test must be 500 VAC or lower.
Failure to heed these guidelines may cause faulty operation.
Withstandvoltagetestprocedure
■ Testing between the output terminal and the input terminal
1. Lay transition wiring between 11 and 14 of connector. *1
2. Lay transition wiring between all input terminals (except CJC) of
connector. *1
3. Connect the withstand voltage tester (with the power turned OFF)
between the transition wiring shown in steps 1 and 2 above.
4. After setting the current limit value of the withstand voltage tester to 10
mA, turn the power ON, and carefully increase the impressed voltage
from 0 V to the specied value.
5. The voltage at the specied value must remain for duration of one
minute.
6. Upon completion of the test, carefully reduce the voltage so that no
voltage surge occurs.
*1: Refer to Figure 5.3 for terminal Number.

protected type instrument are described. For explosion protected type
instrument, the description in this chapter is prior to other description in this
user’s manual.
CAUTION
To preserve the safety of explosion protected type instrument requires
great care during mounting, wiring.
Safety requirements also place restrictions on maintenance and repair
activities. Please read the following sections very carefully.

5. Wiring
5.1 Notes on Wiring
IMPORTANT
• Lay wiring as far away as possible from electrical noise sources such
as large transformers, motors and power supplies.
• To prevent electrical noise, the signal cable and the power cable must
not be housed in the same conduit.
5.2 Loop Construction
The YTA70P is a two-wire temperature transmitter that uses the output
power supply wiring and signal wiring alternately.
The transmission loop requires DC power. Connect the transmitter with the
distributor as shown in Figure 5.1 or Figure 5.2.
For the transmission loop, the load resistance of the distributor or other
instrument to be installed in the loop and the lead wire must be within the
range shown in Figure 5.3.
