NOTE
• The equipment must be installed in accordance with IEC 60079-14 and relevant local
codes.
• The equipment must be installed in accordance with the user’s manual.
• Electrostatic charges on the non-metallic parts (excluding glass parts) or coated parts of the
Field Wireless Access Point must be avoided.
• The thread type of the cable entries must be confirmed according to the user’s manual.
• Screws of power supply terminals must be tightened with specified torque values: 1.2 Nm to
1.4 Nm.
• Cable glands, adapters must be of Ex “n”, Ex “e” or Ex “d” and must be installed so as
to maintain the specified degree of protection (IP Code) according to the environmental
conditions. IP must be at least IP54.
• Keep the cap attached to the antenna connector (N type) until the installation of the antenna
or antenna cables to protect the inside of the connector from exposure of light.
In case the antenna or antenna cables are removed from the connector, the inside of the
antenna connector must be protected from exposure of light.
• The antenna and the surge protective device are simple apparatus.Li and Ci of the simple
apparatus shall be negligible.
• The temperature class of the antennas and the surge protective devices must be
determined in accordance with IEC 60079-14, using Po = 60 mW for ISA antenna
connector.
• The following conditions must be met for the connections to ISA.
(Total Li of simple apparatuses) + (Total Lc) ≤ 3 mH
(Total Ci of simple apparatuses) + (Total Cc) ≤ 0.8 μF
• The equipment must be earthed in accordance with IEC 60079-14, in order to maintain
intrinsic safety. A cable lug or a similar device shall be used to maintain the secureness of
the earth connection. Care must be taken to avoid multi-point earthing since the equipment
is not galvanically isolated from the power supply.
