3.3 Installation
DANGER!
Never install or operate the device in potentially explosive areas, it might cause an explosion that
can result in fatal injuries.
CAUTION!
Always note the following items to ensure a proper and safe installation:
•
Make sure that there is adequate space to the sides.
•
The device must not be heated by radiated heat (e.g. exposure to the sun) to a electronics
housing surface temperature above the maximum permissible ambient temperature. If it is
necessary to prevent damage from heat sources, a heat protection (e.g. sun shade) has to be
installed.
•
Do not expose the indicator to intense vibration.
•
Indicator installed in control cabinets require adequate cooling, e.g. by fan or heat exchanger.
•
Take the relevant IP classification of the enclosures into account (see manufactures plate).
Even an IP67 (NEMA 4X) enclosure should NEVER be exposed to strongly varying (weather)
conditions.
•
When used in very cold surroundings or varying climatic conditions with high humidity (above
90% annual mean), take the necessary precautions against moisture by placing a dry sachet
of silica gel, for example, inside the instrument case. Furthermore, it is required to replace or
dry the silica gel periodically as advised by the silica gel supplier. For further information
about the ambient temperature refer to Technical data on page 27
.
•
Use assembly materials and tools in compliance with the applicable occupational health and
safety directives (assembly materials and tools are not part of the scope of delivery).
CAUTION!
Installation, assembly, start-up and maintenance may only be performed by appropriately
trained personnel. The regional occupational health and safety directives must always be
observed.
