5.Setup
The device can be installed and safely operated both indoors and outdoors.
When you select the installation location, observe the following:
•ATTENTION: All cables should be laid in a way that the data communication is not
interfered with electromagnetic radiation. The appropriate standards for information
technology cabling installation (Part 2: EN 50174-2 Installation planning and practices
inside buildings and Part 3: EN 50174-3 Installation planning and practices outside
buildings) should be taken into account. AlsoEnergy recommends a minimum distance of
1.0 m between data communication cables and power cables.
•Avoid direct sunlight. The shadow of the modules is a preferred location for installation.
•Make sure that no rainwater is able to run from the modules over the cabinet.
•Keep the cables to the device as short as possible in order to minimize cable loss.
•Keep extra cable length to connect the device.
•Mount the device cabinet vertically with the cable glands at the bottom.
•Use the mounting brackets to mount the device at a sufficiently stable wall or rack.
Make sure to follow the prevailing safety regulations when working
with the device. Non-compliance may endanger persons and
technical equipment.
Ensure the protection class IP 66 as defined in the standard EN 60529.
Avoid installing the device in high humidity conditions or during rainfall, as humidity might be
enclosed in the housing and interfere later during operation or damage the equipment.
By means of the supplied material, mount the cabinet as shown
