Installation in zone 2
WARNING: Explosion hazard when used in potentially explosive areas
Make sure that the following notes and instructions are observed and complied with.
•
Observe the specified conditions for use in potentially explosive areas!
•
Install the device in a suitable, approved housing (with at least IP54 protection) that
meets the requirements of EN 60079-15. For this purpose, observe the requirements of
IEC 60079-14 / EN 60079-14.
•
Only connect devices to the supply and signal circuits in Zone 2 that are suitable for op-
eration in Ex Zone 2 and for the conditions at the installation location.
•
In potentially explosive areas, only connect and disconnect cables when the power is
disconnected.
•
Replace the SIM card only when the power is disconnected.
•
The configuration interface may only be used if it has been ensured that there is no po-
tentially explosive atmosphere present.
•
The switches of the device that can be accessed may only be actuated when the power
supply to the device is disconnected.
•
Observe the derating information in the technical documentation.
•
All plug connections must be completely plugged in and, if possible, screwed tightly
and/or locked.
•
The device must be stopped and immediately removed from the Ex area if it is dam-
aged, was subjected to an impermissible load, stored incorrectly or if it malfunctions.
•
Ensure that the radiated wireless power is neither bundled (focused) by the antenna it-
self nor by any inserts in the environment of the antenna, and that it cannot enter neigh-
boring Zones 1 or 0. Please refer to the technical data for the HF output power. It must
not exceed 2 W.
•
The HF cable to the antenna must be suitable for the ambient conditions. Install the ca-
ble so that it is protected against mechanical damage, corrosion, chemical stress, and
negative effects from heat or UV radiation. The same applies to the antenna which is
connected to the cable and which functions as a cable termination.
•
The antenna itself must meet the relevant requirements of EN 60079-0.
