page 7 “General safety instructions”)
.
When selecting the assembly location, also make sure the following
requirements are met:
The installation location should be close to a power outlet.
Adhere to the climatic threshold values listed in the technical data.
Keep the ventilation slits free to ensure good air circulation.
Make sure there is at least 3.94 in (10 cm) of space in front of the
ventilation slits of the casing.
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.
