1、 Operating conditions and site preparation

1. The cabinet is installed.

2. Circuit breakers, wiring cables, ties, etc. It has been prepared and meets the design drawings and installation requirements of the distributor manufacturer for the ready board.

2、 Install the guide rail of the ready board

The guide rail shall be installed horizontally and match with the opening operation hole of the cover plate

3、 Unpacking and installation.
