Installation
► Installation is performed by following the above instructions in the reverse order. Also observe
the following instructions:
CAUTION
Always handle the trailing cable with care
► If a vacuum pump is fitted, also observe the relevant assembly instructions
[00196845‑xx].
► Always handle the new trailing cable with care.
► You might need to enlist the help of a second person.
► Make sure that the flat ribbon cable and the pneumatic hoses are not rubbed against
any parts or folded. Look out for sharp edges.
► Prepare the trailing cable. Place the old and new trailing cables next to one another
and match the length of the new trailing cable hose to the old one.
► If you use the new holder, you will need to dismantle all attached items (boards etc.)
from the old holder and attach them to the new holder.
► If hose ends were damaged during removal, cut these with hose cutters.
► Clean the trailing cable contact surface on the machine base with a dry cloth.
► Carefully insert the new trailing cable into the prescribed position. Make sure you do
not fold or twist the trailing cable.
► Check that the power track chain runs parallel to the machine base. Move the gantry
back and forth.
► If it is difficult to push the hoses onto the tubes, moisten these first with white spirits or
isopropanol.
► Secure screws with Loctite 241 (see below).
Fig.140: Covers
► Secure the screws(2) of the upper cover with
Loctite 241.
 CAUTION!
Do not secure the screws(1) of the lower
cover with Loctite.

► Unplug all electrical connections to the head ad-
apter(1). You may want to mark the position to
make clear assignment easier later on.

► Remove the screws(2) fastening the head ad-
apter.
► In addition, the head adapter is fastened with the
topmost two MHCU screws(1)in each case. Re-
move these two screws as well.
► Carefully pull the head adapter down and off.
The head adapter is connected to the head inter-
face from below via a press-fit connection.
Converting the MHCU
If you have ordered the base adapter without MHCU(s) you will have to convert the MHCU(s). Pro-
ceed as follows:
Fig.144: Head adapter backside
► Remove the two screws(1) fastening the MHCU
on the back of the board and carefully pull the
