– place transistor (B) onto the mounting area
– press the lock-in retaining spring for transistors THFU 2 - 6 (A) into the
groove of the profile (a suitable installation aid will facilitate pressing in)
– Once in place, the spring will keep its position and fix the transistor with a high contact
pressure on the installation surface (the spring remains in its position and it can neither be
moved in a lengthwise direction nor fall it can out of the groove in a cross direction).
