Safety Considerations 2.1. Earthing of Equipment Equipment supplied from the mains must be connected to grounded outlets and earthed in conformity with appropriate local, national and international electricity supply and safety regulations. 2.2. Electric Shock Hazard The risk of electrical shocks due to faulty mains driven power supplies whilst potentially ever present in any electrical equipment, would be minimised by adherence to good installation practice and thorough testing at the following stages: a) Original assembly. b) Commissioning. c) Regular intervals, thereafter. All test equipment must be in good working order prior to its use. High current power supplies can be dangerous because of the possibility of substantial arcing. Always switch off during disconnection and reconnection. 2.3. RF Radiation Hazard RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to AWL’s equipment, must be considered a safety hazard. This condition might only occur in the event of cable disconnection, or because a ‘spare’ output has been left un-terminated. Either of these conditions would impair the system’s efficiency. No investigation should be carried out until all RF power sources have been removed. This would always be a wise precaution, despite the severe mismatch between the impedance of an N type connector at 50Ω, and that of free space at 377Ω, which would severely compromise the efficient radiation of RF power. Radio frequency burns could also be a hazard, if any RF power carrying components were to be carelessly touched! Antenna positions should be chosen to comply with requirements (both local & statutory) regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is capable of producing RF field strengths, which may exceed guideline safe values especially if used with antennas having appreciable gain. In this regard the use of directional antennas with backscreens and a strict site rule that personnel must remain behind the screen while the RF power is on, is strongly recommended. Where the equipment is used near power lines or in association with temporary masts not having lightning protection, the use of a safety earth connected to the case-earthing bolt is strongly advised. 2.4. Lifting and other Health and Safety Recommendations Certain items of AWL equipment are heavy and care should be taken when lifting them by hand. Ensure that a suitable number of personnel, appropriate lifting apparatus and appropriate personal protective equipment is used especially when installing Equipment above ground e.g. on a mast or pole and manual handling precautions relevant to items of the weight of the equipment being worked on must be observed at all times when handling, installing or dismounting this equipment.

Chemical Hazard Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes used in devices within equipment produced by Axell Wireless Ltd. Beryllium oxide dust can be toxic if inhaled, leading to chronic respiratory problems. It is harmless if ingested or by contact. Products that contain beryllium are load terminations (dummy loads) and some power amplifiers. These products can be identified by a yellow and black “skull and crossbones” danger symbol (shown above). They are marked as hazardous in line with international regulations, but pose no threat under normal circumstances. Only if a component containing beryllium oxide has suffered catastrophic failure, or exploded, will there be any danger of the formation of dust. Any dust that has been created will be contained within the equipment module as long as the module remains sealed. For this reason, any module carrying the yellow and black danger sign should not be opened. If the equipment is suspected of failure, or is at the end of its life-cycle, it must be returned to Axell Wireless Ltd. for disposal. To return such equipment, please contact the Operations Support Department, who will give you a Returned Materials Authorisation (RMA) number. Please quote this number on the packing documents, and on all correspondence relating to the shipment. Polytetrafluoroethylene, (P.T.F.E.) and P.T.F.E. Composite Materials Many modules/components in AWL equipment contain P.T.F.E. as part of the RF insulation barrier. This material should never be heated to the point where smoke or fumes are evolved. Any person feeling drowsy after coming into contact with P.T.F.E., especially dust or fumes should seek medical attention. 2.6. Laser Safety General good working practices adapted from EN60825-2: 2004/ EC 60825-2:2004 Do not stare with unprotected eyes or with any unapproved optical device at the fiber ends or connector faces or point them at other people, Use only approved filtered or attenuating viewing aids. Any single or multiple fiber end or ends found not to be terminated (for example, matched, spliced) shall be individually or collectively covered when not being worked on. They shall not be readily visible and sharp ends shall not be exposed. When using test cords, the optical power source shall be the last connected and the first disconnected; use only approved methods for cleaning and preparing optical fibers and optical connectors. Always keep optical connectors covered to avoid physical damage and do not allow any dirt/foreign material ingress on the optical connector bulkheads. The optical fiber jumper cable minimum bend radius is 3cm; bending to a smaller radius may result in optical cable breakage and excessive transmission losses. Caution: The FO units are NOT weather proof. 2.7.

Equipment Overview Fiber Optic, Uplink, Band Selective, 800MHz, Booster Amplifier Part Number 60-275001 is built into an 8U, 19” rack mount shelf. The amplifier is used to filter and amplify the signal levels of one 800MHz band, 812.0MHz to 816.0MHz; in the Uplink direction only. The Uplink Optical signal is received from Fiber Optic Transmitter Part Number 60-275101 via Fiber Optic cable at the FC/APC port labelled “F/O” (annotated “A” in 3.4.); the optical Uplink signal then enters Fiber Optic RX Module 20-005501 which demodulates the Optical signal to RF. The RF signal then passes through a Bandpass Filter 02-011601 tuned to pass the Uplink band and to reject out-of-band noise; after leaving the Bandpass filter the Uplink signal passes through the Variable Switched Attenuator 10-000701 which can introduce up to 30dB of signal attenuation if required. The attenuator is controlled by a set of four toggle switches (annotated “E” in section 3.5.) on the front panel of the Amplifier shelf; each switch is clearly marked with the attenuation it provides, and the total attenuation in-line is the sum of the values switched in. After leaving the switched attenuator the Uplink signal passes first through the AGC Attenuator Module 17-016401 (which is controlled by AGC Detector Module 17-019801 fitted further on in the RF path) and then through a 1W Low Power Amplifier 12-030302 which provides 30dB of gain. The Low Noise Amplifier is followed by a 20W Power Amplifier 12-023301 which provides 36dB of gain and then the Uplink signal passes through the AGC Detector Module 17-019801 which regulates the gain level by adjusting AGC Attenuator Module 17-016401. The AGC Detector Module monitors the RF level being delivered by the power amplifier, and when a certain threshold is reached it begins to increase the value of the AGC Attenuator Module to limit the RF output to the (factory set) threshold. Therefore overloading of the power amplifier is avoided. After passing through the AGC Detector Module the Uplink path passes through a second Bandpass Filter 02-011601 to further reject out-of-band noise and then through VSWR Monitor 21-003207. Upon leaving the VSWR Monitor the Uplink signal exits the Amplifier shelf for the Uplink Antenna System via the N type port labelled “RF Base” (annotated “F” in section 3.5.). The Amplifier is powered from mains AC at 110V which drives an internal 400W PSU module providing 24V DC for the power amplifier; a DC/DC converter provides 12V DC for the remaining active modules. The Amplifier has an alarm system; both of the amplifier modules, the PSU, DC/DC converter, the F/O RX and the VSWR Monitor modules carry their own voltage-free, dry contact alarm relay outputs which are summed at the 15 way “D” alarm output connector on the rear of the case (annotated “L” in section 3.5.).
