ABB HIEE300661R1 Output expansion card

Terminal board and relay board mounting directions Mount a terminal board and a relay board in the directions as shown in the below figure. When mounting SBD2D in the direction of b or c, the following conditions must be met. • When the ambient temperature is 60 °C or lower, the total load current of the SBD2D must be kept within the specified value of 8 A or lower. 

• When the ambient temperature is at 70 °C, the total load current must be 6 A or less. 

• In case the ambient temperature is in between 60 and 70 °C, reduce the total load current from 8 A maximum by the rate of 0.2 A/°C.

Mounting a terminal board by itself 

Install all the heat sources above the terminal board or terminal board wiring. Provide a heat shield in case installation of the heat sources below or sideway of the terminal board is unavoidable. Installing terminal board in a cabinet Install all the heat sources above the terminal board or terminal board wiring when those are mounted in a cabinet. Provide a heat shield in case installation of the heat sources below or sideway of the terminal board is unavoidable.

Mounting an SAT145 module with SBT4D terminal board 

Prevent the terminal board from being influenced by the ambient temperature in order to keep the reference junction compensation accuracy, as detailed conditions are shown below. The reference junction compensation accuracy is specified when the ambient temperature is stable. When the temperature fluctuates, the accuracy may vary until it becomes stable.
