1.Installation：

1）This product is used in the following environmental standards.
（IEC61010-1）[Overvoltage categoryⅡ、class of pollution 2]
2）This product is used in the following scope:surrounding environment, temperature, humidity and environmental conditions.
Temperature：0～50℃；Humidity：45～85%RH;Environment condition：Indoor warranty,The altitude is less than 2000m.
3）Please avoid using in the following places:

The place will be dew for changing temperature;with corrosive gases and flammable gas;with vibration and impact;with water, oil, chemicals, smoke and steam

facilities with Dust, salt, metal powder;and with clutter interference, static electric and magnetic fields, noise;where has air conditioning or heating of air blowing

directly to the site.
4）On the occasion of the installation, please consider the following before installing several.

In order to protect heat saturated, please ensure adequate ventilation space.

Please consider connections and environment,and ensure that the products below for more than 50mm space.

Please avoid to installed over the machine of the calorific value(Such as heaters, transformer, semiconductor operations, the bulk resistance).
When the surrounding is more than 50℃, please using the force fan or cooling fans.But don't let cold air blowing directly to the product.

In order to improve the anti - interference performance and security, please try to stay away from high pressure machines, power machines to install.

Don`t install on the same plate with high pressure machine and the product.

The distance should be more than 200mm between the product and power line.

注

2.Cable caution：
1）Please use specified compensation wire in the place of TC input;Please use insulated TC if the measured device is heated metal.
2）Please use the cable of lesser resistance in the place of RTD input,and the cable(3 wire) must be no resistance difference,but the total length is within 5m.
3）In order to avoid the effect of noise,please put the input dignal away from meter cable,power cable,load cable to wiring.
4）In order to reduce the power cables and the load power cables on the effect of this product,please use noise filter in the place where easy to effect.

You must install it on the grounding of the disk if you use the noise filter,and make the wiring to be shortest between noise filter output side and power connectors.

Don`t install fuse and switch on the wiring of noice filter output side,otherwise it will reduce the effect of noise filter.
5）It takes 5s from input power to output.If there is a place with interlocking actions circuit signal,please use timer relay.
6）Please use twisted pair with a shield for analog output line,and to ensure the reliabilty of signal,and connect Common mode choke on the front of sinal receiver to suppress

lines affected by interference if necessary,so that to
7）Please use twisted pair with a shield for remote RS485 communication cable,and deal with the shield on the host side earth,otherwise it will reduce the effect of noise filter.
8）This product is not the fuse;please set according to rated voltage 250V,rated current 1A if you need;fuse type:relay fuse.
9）Please use the suitable screw force and crimp terminal.
The screw terminal size：M3X8（with 6.8X6.8 square base）
Recommended tightening torque：0.4N.m
Proper cables：0.25～1.65mm single cable/multiple core cable
10）Pla don`t put the Crimp terminal or bare wire part contact with adjacent connector.

Model Illustration

：TE series is only one 4~20mA output function.For the size of 6、8、9,when relay output/SSR output is together with DC 4~20mA,it has discrimination with “I”;
for example:IR,IS,etc,but it has not this type model for the size of 4、7.

Please note the input signal type when you choose the model. 1st type:TC/RTD/mV/Rt;2nd type:mA/V
