Chapter 2 Installation of this Device
• Temperature:
Install the device in an area that satisfies the following temperature conditions.
Ambient temperature
JT _9 _ _S with indicator: -20 - +55 °C
JT _9 _ _S without indicator: -20 - +60 °C
JT _9 _ _W with indicator: -20 - +55 °C
JT _9 _ _W without indicator: -20 - +60 °C
Pressure-receiving part (main unit) contact liquid temperature: 110 °C
Caution
If this temperature is exceeded, explosion-proof performance specifications cannot be
guaranteed. If there is a chance of this, take measures to ensure that the temperature
stays within the temperature range, such as carrying out heat insulation measures or
selecting a well-ventilated area.
Be sure to install the provided (specified) pressure-resistant packing cable gland to the
signal wiring port of the device.
Also, if the orientation of the wiring needs to be changed, use the provided elbow
joints. In order to ensure the explosion-proofing performance specifications based on
explosion-proofing certification, do not use any items other than the pressure-resistant
packing cable gland and the elbow joints.
For the wiring, use cables with the following maximum allowable temperature.
JT _9 _ _S with indicator: 65 °C
JT _9 _ _S without indicator: 70 °C
JT _9 _ _W with indicator: 60 °C
JT _9 _ _W without indicator: 65 °C
