Design

The control unit is incorporate into the front door of the switchboard. When installed, the front meets the
protection class IP 44. The two rows of LEDs are marked with interchangeable labels. The relay units
are mounted on the mounting plate and linked to the control unit in the door with the supplied cable.
The control unit has an optical fibre and a USB interface for the connection of a PC. Only one of them can
be used at a time
