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
