2.5 Use of a Transceiver
Although the temperature transmitter is designed to resist influence 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 specified value.
5. The voltage at the specified 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.
