PI-HMI can be installed in two ways: eit-
her in a wall box/panel front or directly
on a flat surface.
6.2.5 Installation
The back cover of the PI-HMI is equipped
with a keyhole-shaped opening which
can be used to hang the unit on a flat
surface
(see illus. 1)
. Use a screw that is
max. 3.5 mm in diameter with a head no
larger than 9 mm.
6.2.5.1 Installation on flat surface
If PI-HMI is to be installed in a wall box
or panel front, the back cover must be
removed. Firstly, the front cover must be
detached by gently releasing the catch
on the bottom of the unit with a flat
screwdriver and then tipping the cover
outwards
(see illus. 2)
.
Once the front cover has been detached,
the two screws holding the back cover in
place can be removed
(see illus. 3)
.
The back cover can now be detached and
the front cover refitted. The baseplate is
equipped with several screw holes. The
dimensioned drawing
(see illus. 4)
can
be used as a drilling template. The base-
plate should be secured with at least two
screws tightened to a torque of max. 0.8
Nm. Installation depth is 20 mm.
