Mounting the terminal
Procedure
1.
Cut the sealing strip in appropriate lengths.
The strip is delivered with the mounting kit. In the semi-flush mounting
kit two strips are delivered, one for the terminal and one self-adhering for
the distance frame. The length of the strip is enough for the largest avail-
able terminal.
Cut the strip into four, one part for each side of the terminal. When cut-
ting, make sure no gaps will be present between each part. Preferably,
seal the joints at the corners (posNo 1).
Repeat the procedure for the self-adhering strip which are to be adhered
to the distance frame.

Dispose the strip remains.
The remains should be source separated as soft plastic.
