7) Deleting the CA Certificate [CA-KEY]
For the secure communication between the device (e-RDS) and the UGW, an authentication technology from a certification authority is used. A license has been
issued from the certification authority. For this reason, the devices are shipped with the CA (Certificate Authority) certificate enabled in advance to prove the license
