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 locations where this can occur, provide additional protection with some form
of roofing.
● 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.

Optional installation components
The following separately certified components can be installed optionally:
● Terminals:
– Ex e for the connection of cable cross-sections >4 mm,
– Ex i for wiring of intrinsically safe signals (blue); these may only be used for Ex i signals.
Make sure when arranging intrinsically safe and non-intrinsically safe terminals that they
are separated ("thread measure") by at least 50 mm.
● Temperature sensors:
For monitoring the temperature inside the enclosure,
● Relays, disconnectors and fuses:
For interrupting, switching or protecting individual signal circuits.
● Command and signaling devices:
For manual switching (control switch) or optical display (indicator lamps) in the enclosure
wall.
● FO couplers:
For connecting the PROFIBUS of the ET 200iSP by means of FO cable
● Lightning protection components:
For protecting the ET 200iSP components from lighting strikes when the enclosure is
installed in exposed locations.
