(1) Communication port for reading and configuring UNICOM 300 on location.
This communication port is suitable for an infrared communication head in combination with the
software program UNITOOL.
(2) Opening the housing.
Turn the two-cylinder head screws until the screw comes loose (anti-loss screw). Then open the
housing on the right side. It is possible that the sealing will stick, making the housing more difficult to
open.
Closing
the housing must be done with caution. The hinge of the lid has some
tolerance so that the seal in the lid, when closed, can connect to the underside of the
housing.
Make sure that when closing the lid it is not pushed up or down. Make sure that the
sealing ring in the lid is clean.
(3) Breather opening for pressure equalization between UNICOM 300 and ambient atmosphere.
Behind the breather opening a membrane is placed that prevents ingress of moisture.
Take care not to damage the membrane. The membrane must not be covered. See
also figure 3, point 3.
