1.5 Installation in Zone 2
• Observe the specified conditions for use in potentially explosive areas! Install the de-
vice in suitable approved housing (with at least IP54 degree of protection) that meets
the requirements of EN 60079-15. Also observe the requirements of 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 snap the device on or off the DIN rail connector and
connect/disconnect cables when the power is disconnected.
• The switches of the device that can be accessed may only be actuated when the power
supply to the device is disconnected.
• The device has to 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 transmission power.
• 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 must meet the requirements of EN 60079-0 with regard to housing and
electrostatic charge. Otherwise install the antenna in housing that meets the require-
ments of EN 60079-0 and EN 60079-15 and has at least IP54 degree of protection
(EN 60529).
Notes for antennas
• Only use antennas approved for the Ex area (see Section “Accessories” on page 159).
• The intrinsically safe antennas support universal communication in various HF areas.
The antennas are intended for use in potentially explosive areas that require
1G equipment. Connection is via antenna barriers (Order No. 2702198) with separate
approval as intrinsically safe equipment.
• Observe the safety notes in the documentation for the respective antenna.
WARNING: Explosion hazard when used in potentially explosive areas
Make sure that the following notes and instructions are observed.
The RAD-2400-IFS-JP wireless module does not have ATEX approval. It is not suitable
for use in potentially explosive areas. Only install this wireless module in the safe area.
