There are 2 types of front protection options in PDS panels. In Internal front protection option; the panel is protected with full size glass or closed door from outside, and the front surface of sections are protected with internal hinged covers from inside. Thus, external intervention to equipment is limited.
Provides high degree IP protection.
Since there is a limited area between outer door and inner cover, there are limitations in using levers of the equipment.
In External front protection option, each equipment section can be opened independently.
It is easy to intervene from outside.
