6.1 Overview
The modular design structure of this relay enables a qualified commissioning technician to easily
check and locate the damaged hardware modular, so as to eliminate the fault in the very first time.
The hinged front panel allows easy access to the HMI modules and the back-plugging design
makes it easy to upgrade, maintain or replace any module.
There are several types of hardware modules in this relay, which play different roles in the
practical application. The specific modules can be configured flexibly according to the practical
engineering demands.
The overall hardware designing frame of this relay is shown as below.
