2 INSTALLATION
2.1 Precautions for use
For your safety, ensure that you are working on a device that is powered off before you do
anything!
The housing of the U•H1 unit may only be opened by qualified technicians.
The U•H1 unit must be placed in a room that does not have an explosive atmosphere and
must always be easy to access.
The housing of the U•H1 unit can be inverted. It can be used in such a way that electric
cables can be inserted from the top, or in such a way that they can be inserted from the
bottom. However, to guarantee optimal sealing, it is recommended that you always insert the
cables from the bottom.
The housing of the device is IP65-certified and is therefore protected against the presence of
dust and water, provided that the installation instructions are followed.
The housing has several machined apertures. You will need to clear these machined
apertures with a flat screwdriver and hammer to insert the cable glands.
Before drilling these holes with a tool, it may be useful to remove the electronic part to
avoid accidental damage.
Important note:
Never place the U•H1 control unit,
▪
a high-voltage cables or a power cable,
▪
coaxial cables or transmitters,
▪
welding stations or frequency regulators.
2.2 Placing the U•H1 unit
The U•H1 unit must be placed on a smooth, flat surface. Two fixing systems, a drilling plan
and a quick installation guide are supplied with the device. You can choose to fix the unit
using the housing or the four feet provided.
It is also possible to fix the U•H1 unit on a DIN rail (optional). Please contact your DALEMANS
sa/nv representative for more information.
