5.3 Installing the enclosure outdoors
The enclosure should have at least IP56 protection when installing outdoors. This prevents
damaging amounts of dirt or water from penetrating the enclosure under normal ambient
conditions. Take the following additional protective measures depending on the environment of
the installation location:
• Avoid subjecting the enclosure permanently to water (for example, snow).
• Remember that direct sunlight can cause excessive temperatures in the interior of the
enclosure. In such cases, shading must be provided as additional protection.
• Note that opening the enclosure at ambient temperatures below 0 °C can damage the seal
as a result of freezing.
• Condensation may be produced within the enclosure due to temperature variations. Climate
nozzles are therefore installed to permit drainage and pressure compensation. Ensure when
mounting the enclosure that the climate nozzles are at the lowest position.
• If you want to use the device in an aggressive environment, check whether this is possible
with the material in question.
5.4 Optional installation components
The following separately certied components can be installed optionally:
• Terminals:
– Exe for the connection of cable cross-sections >4mm,
– Exi for wiring of intrinsically safe signals (blue); these may only be used for Exi signals.
Make sure when arranging intrinsically safe and non-intrinsically safe terminals that they are
separated ("thread measure") by at least 50mm.
• Temperature sensors:
For monitoring the temperature inside the enclosure,
• Relays, disconnectors and fuses:
For interrupting, switching or protecting individual signal circuits.
Note
Components may only be replaced when the system is de-energized.
• FO couplers:
For connecting the PROFIBUS of the ET 200iSP by means of FO cable
