Protege PRT-CTRL-SE - 13.1 Current and Validation Example 1

32
?
The isolated communicaons interface on the Protégé® SE Integrated System
Controller uses full galvanic isolaon to prevent ground loop noise and cross phase
ground dierenal. This is a very important feature of the product family and the
correct connecon of power to this isolated secon will ensure the correct
operaon of the communicaons network.
13.1 Current and Validaon Example 1
The example shown below refers to the specicaon’s table needed to help ensure the correct
installaon of the Protégé® SE Integrated System Controller. Specicaons have to be validated to
ensure that individual maximum currents and total combined current are not exceeded.
