Undo the terminal end holder on the right-hand side of the
most recently assembled module. Use a screwdriver to do so.
Lever the terminal end holder out of the top hat rail as shown

Unlock the top hat rail module on the rail. Pull the two orange
tabs on the base of the module away from the top hat rail.
Use a suitable screwdriver to do so.
5.
Carefully pull the top hat rail module upwards away from the
top hat rail.
6.
Pull the exposed bus connector on the top hat rail a little to
the right until it is released from the connection to the bus
connector of the previous module.

or bottom) away from the top hat rail. Remove the bus con-
nector from the top hat rail.
8.
Repeat steps 3 to 6 for each module to be removed.

Disassembly is completed by attaching the terminal end
holder onto the right-hand side of the remaining module. Posi-
tion the terminal end holder as closely as possible against the
right-hand side of the remaining module. Mount the terminal
end holder here, with the upper part inside the top hat rail.
10.
Push the bottom part downwards using a screwdriver placed
into the notch above the retaining lug. At the same time, push
it towards the centre of the top hat rail until the terminal end
holder engages in the top hat rail.
✔ Disassembly is complete once the operating voltage has
been switched back on again. The D‑ISC100 can then be
used again.
