The REF542 plus consists of two parts, a Central Unit and a separate Human Ma chine Interface (HMI) as the Control Unit. The Central Unit contains the power supply,processor and analog and binary Input and Output (I/O) modules, as well as optional modules for supplementary functions. The HMI Control Unit is a stand-alone unit with its own power supply. It can be installed on the Low Voltage (LV) compartment door or in a dedicated compartment close to the Central Unit. The HMI is normally used toset the protection parameters and to locally operate the switching devices in the switchbay. An isolated and shielded twisted pair according to the RS485 standard in terface shall be used for the connection of the HMI as the Control unit to the Central Unit.
