OVERVIEW The Solexy RX series explosion proof and intrinsically safe antenna coupler is an integrated protection device that facilitates non-ex certified radio antenna installation in hazardous areas. The patented (7,057,577) RX series coupler features a barrier circuit which blocks power voltage in the event of a radio transmitter/receiver fault and is encapsulated and housed in an explosion proof stainless steel body. By limiting transmitted power per local regulations and ensuring the threshold power requirements for the area of installation are met, the RX coupler can easily be used with most passive antennas. When a radio must be used in a safe area, the RX coupler can still protect the output signal using a cable to connect to an antenna that is installed in a hazardous area. SAFETY INSTRUCTION TO HAZARDOUS AREA INSTALLATION To avoid serious or fatal personal injury or major property damage, read and follow all safety instructions in this manual. Keep this instruction manual always available. If you require assistance, please contact SOLEXY. CONDITIONS FOR USE 1. Solexy RX series antenna coupler must be connected to RF source with minimum internal impedance of 50Ω. 2. Solexy RX series antenna coupler must be installed and maintained according to suitable standards for electrical application in potentially explosive atmospheres (e.g. IEC/EN60079-14, IEC/EN60079-17 or other national standards). 3. Connected antennas must be assessed, installed and maintained according to suitable standards for electrical application in potentially explosive atmospheres (e.g. IEC/EN60079-0, IEC/EN60079-14, IEC/EN60079-17 or other national standards). 4. Solexy RX series antenna coupler does not provide any RF power limitation. The threshold power must be limited by the user in order to achieve the levels defined in IEC/EN60079-0 Table 4. 5. The RX series antenna coupler is designed to be used with a suitable enclosure with mechanical protection of the input side that utilizes one of the protection types listed in Clause 1 of IEC/EN60079-0 when it is installed in an Ex area. The protection type utilized shall be applicable to the specific area of use (i.e. Gas or Dust). 6. When installed in a safe area the input side must be protected from sun exposure. For example by using a housing or by being in an indoor area. 7. The verification and maintenance of the electrical equipment must be performed per IEC/EN60079-17. 8. Suitable trained personnel shall carry out installation according with applicable code practice. 9. The user should not repair this equipment. 10. The user should not modify the equipment related components inside. 11. Do not dispose this product or the components into the environment. National regulations for waste disposal and recycling must be observed. 12. Maximum service temperature, Ts, of RX antenna coupler and maximum service temperature of equipment it is installed in shall not exceed +85 C. INSTALLATION For proper installation, see the applicable control drawing: Drawing Coupler Description Model DC00074 RX antenna coupler installation drawing RXF, RXN, RXS, RXT, RXB 1. Do not attach radio connection to radio until housing has been fully threaded into enclosure. 2. If lightning suppressor is used, connect to output side of the coupler. 3. Antenna and cable connections should be finger tightened only. Over tightening can cause permanent damage resulting in equipment failure. 4. RX series antenna couplers with M25 straight threads (RX*M) must be secured from loosening when installed in an Ex d enclosure. Use of LOCTITE or similar sealing adhesive is acceptable and shall be applied to threaded joint prior to mounting the RX antenna coupler to the Ex d enclosure so the joint is secured against loosening.

MAXIMUM RADIO OUTPUT POWER The tables below provide the maximum allowable RF power that may be input to the RX coupler without exceeding intrinsically safe conditions. The tables do not consider any cable loss between the RF transmitter and the RX coupler and may therefore be considered as the maximum allowable RF transmitter output power when the RX coupler is directly connected to a RF transmitter. It must not be possible for an end-user to adjust the RF transmitter output power by software control or any other means if the maximum adjustable power exceeds those values in the tables below. The maximum permissible radio output power is determined by the equipment group the device will be operating, radio operating frequency and model frequency code of RX series coupler. For frequencies between table values, use next highest table frequency value (i.e. for 960MHz, use table values for 1000MHz). Added cable loss between the RF transmitter and the RX coupler may allow the RF transmitter output power to exceed the values in the table as long as the cable loss ensures the power at the input of the RX coupler is less than or equal to the values provided in the tables where: Max RX coupler input power (dbm) = Table Value (dbm) Table Value (dbm) RF transmitter output power (dbm) coax cable loss (db) MAXIMUM PERMITTED RF THRESHOLD POWER (Pth) The RF threshold power, sometimes called the effective isotropic radiated power (EIRP), as defined in IEC/EN60079-0, is the product of the effective output power of a radio transmitter multiplied by the power gain of a connected antenna. The maximum threshold powers for each equipment group as defined by Table 4 in IEC/EN60079-0 are provided below. Because most antennas list the gain relative to an isotropic radiator (dbi) instead of the raw power gain, it is often easier to simply add the antenna gain in dbi to the radio output power in decibel-milliwatts (dbm). Any added cable loss between the RF transmitter output and the RX input, or the RX output and the antenna may also be factored in. Pth(dBm) = RF transmitter output power (dbm) + Antenna gain (dbi) Coax cable loss between RF transmitter output and RX coupler input (db) Coax cable loss between RX coupler output and antenna (db) Note that the RX coupler input power is the combination of the RF transmitter output power and the cable loss connecting the transmitter output to the RX coupler input. Therefore, the formula can also be written as: Pth(dBm) = RX coupler input power (dbm) + Antenna gain (dbi) Coax cable loss between RX coupler output and antenna (db) The resulting threshold power calculated by the above formula MUST be below the threshold power for the operating area group rating given in Table 2. A radio output power lower than those provided above may be used to allow for an antenna with a higher gain. In case of device with multiple outputs and multiple antennas, each threshold power is calculated separately for each output/antenna. Gain of multiband antennas should be evaluated separately at each individual frequency. High gain directional antennas on the same device should not be directed in the same direction.
