3.2 Dismounting
For dismounting, the leads need not be disconnected. Before removing the upper
parts of the connectors, the upper parts and the corresponding lower parts must be
marked, because these terminals are distortion-proof but not confusion-proof. For
releasing the upper part of a terminal, the two red ejectors of a terminal row must
be pressed towards the p.c.b. using a screwdriver, if necessary. To release the unit
from the mounting rail, pull the two lateral catches forwards by approx. 5 mm (unit
is released) and remove the unit from the rail by tipping it upwards or downwards.
For replacing an “inner” unit of several ones mounted side by side, start by relea-
sing the catch of a unit (and the catch of the next one!) at one end of the row and
shift the unit laterally. Repeat this procedure up to the unit to be replaced. When its
catches are released at both sides, it can be removed from the rail by tipping it up
or downwards.
