Operating Instructions, 10/2017, A5E39895543-AA
Minimum spacing
The PN/BACnet LINK is designed for natural heat dissipation through convection. Therefore
observe sufficient clearances:
●
For horizontal mounting position: At least 35 mm above and below the PN/BACnet LINK
●
For vertical mounting position: At least 35 mm to the left and right of the PN/BACnet LINK
Provide sufficient space for the connection of supply voltage, Ethernet and BACnet bus.
Also make sure that a depth of at least 25 mm remains clear between the module front and
the inside of the enclosure / control panel.

Humidity and atmospheric pressure
Ensure that there is no condensation at a relative humidity between 10% and 95%.
Ensure that the atmospheric pressure is between 795 hPa and 1080 hPa. This corresponds
to an installation height of -1000 m to +2000 m.
Pollution degree
The PN/BACnet LINK is designed for pollution degree 2. Pollution degree 2 according to the
EN 50178 standard is non-conductive contamination in the normal case which can briefly
become conductive as a result of condensation when the device is not in operation.
Pollution of conductive parts through dust, humidity and air pollution can result in fault
conditions and electrical faults in the PN/BACnet LINK.
Degree of protection
The housing of the PN/BACnet LINK has IP20 degree of protection according to IEC 60529.
The PN/BACnet LINK is also rated as "open type" or "open equipment" according to UL
61010-2-201 or IEC 61010-2-201.
If the PN/BACnet LINK is located in an area in which pollution of conductive parts can occur,
the PN/BACnet LINK must be protected by an enclosure with the corresponding degree of
protection. IP54 is a protection class that is generally used for electronic systems in heavily
polluted environments and may be suitable for your application.
