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.
