Note 3. Installation
WARNING
• POTENTIAL ELECTROSTATIC CHARGING HAZARD – SEE INSTRUCTIONS
• DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE MAY BE PRESENT
NOTE
• The equipment must be installed in accordance with IEC 60079-14 and local electrical
codes.
• The equipment must be installed in accordance with the user’s manual.
• 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 and/or blanking elements shall be of type “n”, type “e” or type “d”
and must be installed so as to maintain the specified degree of protection (IP Code) of the
equipment.
• 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 arrester are simple apparatus.
• The temperature class of Antenna and Arrestor must be determined in accordance with
IEC 60079-14, using Po = 60 mW for ISA antenna connector, and Po = 64 mW for WLAN1/
WLAN2 antenna connector.
• The following conditions must be met for the connections to ISA, WLAN1 and WLAN2:
(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.
