1 General
The FernTel IP Z2 UL telephone is an explosion proof UL certified version of the

• Storage and transport temperature:
o
-25°C ≤ Ta ≤ +70°C (-13°F ≤ Ta ≤ +158°F)
2 Commissioning
For operation and commissioning, the application of standard IEEE 802.3af is
compulsory.
The FernTel IP Z2 UL telephone must be connected to a LAN (Local Area Network)
connection equipped with PoE (Power over Ethernet).

telephone. Thus the LAN plug for the LAN cable is no longer part of the delivery.
Instead of that a plug socket for cable mounting will be delivered.
