Release 16 03/2021
Select the assembly location according to the safety guidelines (see on
page 7 “Safety instructions”) .
When selecting the assembly location, also make sure the following
requirements are met:
 The assembly location can be accessed for maintenance and repair work.
 The LED display elements are clearly visible.

Twisted pair cables are at a sufficient distance from potential sources of
electrical interference, such as power supply cables.
 The device has a separate power source with a ground connection. The
power supply can be interrupted by means of a separate isolator or power
switch. We recommend using overvoltage protection for all devices.
Note: The shielding ground of the connectable twisted pair cables is
connected to the front panel as a conductor.
2.2.2 Mounting on a flat surface
Before operating the device on a flat surface, such as a table, stick the
supplied casing feet onto the bottom of the device, with approx. 0.8 in (2 cm)
of space from the corners.

If necessary, remove any dirt from the bottom of the device where you
want to place the stick-on feet.

Remove the protective foil from the adhesive surface of a casing foot and
attach the casing foot on the device.
2.2.3 Mounting in a switch cabinet
The devices are designed to be mounted in a 19" switch cabinet.
By mounting your MACH4002 device in a 19" switch cabinet on sliding/
mounting rails, you provide a more stable position for your device in
environments subject to vibration.
Note: For more information on sliding/mounting rails and how to install them,
please contact your switch cabinet manufacturer.
If you are operating the device in a 19" switch cabinet, you must install
sliding/mounting rails (not included in the delivery) to hold the weight of the
device.
NOTE
VIBRATIONS
Assemble the device in a 19" switch cabinet on sliding/mounting rails.
Non-adherence to these instructions can lead to material damage.
