NOTE
• The equipment must be installed in accordance with EN 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 and adapters must be of Ex “d” (or “db”) for Ex “d” (or “db”) installations.
• 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 antenna and the surge protective device must be determined
in accordance with EN 60079-14, using Po = 130 mW for ISA antenna connector.
• The following conditions must be met for the connections to ISA
(total Li of simple apparatuses) + (total Lc) ≤ 0.5 mH
(total Ci of simple apparatuses) + (total Cc) ≤ 0.09 μF
• The equipment must be earthed in accordance with EN 60079-14, in order to maintain
intrinsic safety. A cable lug or a similar device must be used to maintain the secureness of
the connection to the equipment. Care must be taken to avoid multi-point earthing since the
equipment is not galvanically isolated from the power supply.
• A marking to indicate type of electrical connection is at the back side of the electrical
connection block.
marking M : M20(ISO) pitch 1.5
marking N : 1/2 NPT
• In order to prevent the earthing conductor from loosening, the conductor must be secured
to the terminal, tightening the screw with appropriate torque. Care must be taken not to twist
the conductor.
