suitable for the intended application.
Observe the occurring extraction forces acting on the fixing
anchors and screws.

anchors and screws. The rated extraction forces for the respective
application (wall or ceiling mounting) and cabinet are listed in the
following table.
Application Rated extraction forces
1 x 21S-SUB 620 N
2 x 21S-SUB 1200 N

A corresponding fixing template is supplied with these mounting
instructions. Refer to Þ Chapter 2 "Z5555 Fixing template"
on page 9.
Preparing the cabinet
The threaded inserts of the cabinet are covered by dummy caps in
cabinet color. To remove the caps, proceed as follows:
1. Cut out the caps along the recessed spline using an
appropriate cutting knife.
2. Carefully take off the caps and ensure the cabinet coating is
not peeled off.

Assembly
NOTICE!
Only use the supplied and specified screws [2], otherwise there is
a risk of damaging the threaded inserts.
Always use the spring washers [3] and U washers [4] to prevent
the bolts from slackening.
Always place the rubber pads [5] between the bracket and the
cabinet to prevent the cabinet coating from scratching during
assembly and adjustment.
Tools required:
▪ Open-ended spanner/wrench (size #17)
1. Starting on one side, first align one hole of the rubber pad
with one threaded insert.
2. Insert one screw together with the spring and U washers.
3. Align the second hole of the rubber pad with the second
threaded insert.
4. Insert the second screw together with the spring and
U washers.
5. Tighten both screws.
↳This will simplify the attachment of the rubber pad on the
opposite side.
6. On the opposite side, proceed in the same manner.
1.6 Z5555 Adjustments
To align the cabinet to its desired angle, proceed as follows:
1. Slightly slacken all screws.
2. Align the cabinet to its desired angle.
3. Finally tighten all screws.
