The description is applicable for DTU-E1CAS, REX-BRD0002 or 2/ROFNB 157 13/1, DTU-E1 CCS REX-BRD0003 or 2/ROFNB 157 13/6 and DTU-T1, REX- BRD0021 or 2/ROFNB 157 13/3 and 2/ROFNB 157 13/2 .

The Modular Cabinet is provided with a ground strip to connect the cables from the DTUs and the CLUs/SLUs to ground. These ground connections are necessary for EMI suppression.
