2. 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.
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.
c) Regular intervals, thereafter.
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 50, and that of free space at 377, which would severely mitigate against 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 Cell Enhancers above ground e.g. on a mast or pole.

2.5. 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 fibre ends or connector faces or point them at other people, Use only approved filtered or attenuating viewing aids. Any single or multiple fibre 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 fibres 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 fibre jumper cable maximum bend radius is 3cm; any smaller radii may result in optical cable breakage or excessive transmission losses. Caution: The FO units are NOT weather proof.
2.7. Emergency Contact Numbers

3. Tri-Band Cable Signal Combiner 60-214702
Tri-Band Combiner 60-214702 is built into a wall-mounted, environmentally protected (IP65) aluminium alloy case; RF ports and connectors are also IP65 standard making the entire enclosure and connecting ports weatherproof. The door is fitted with three locking door handles which also serve to locate the door onto the case. Caution, the door is not attached to the case when the locking door handles are opened.
The Combiner has connections for various RF inputs and outputs across three bands; AWS, PCN and Cellular.
AWS and PCN Downlink signals are received from the operators’ base stations, filtered and combined into a single path and then passed to local LCX antannas, a portion of the Downlink signal is tapped off and fed to a fibre optic transmitter which modulates the RF signal onto a laser for transmission to the Remote Repeater 60-214701 as optical signals over fibre optic cable.
AWS and PCN Uplink signals are received from the local LCX antannas, filtered and amplified before being split into their respective band/frequency allocations and fed to the operators’ base stations. Optical signals from the Remote Repeater 60-214701 are demodulated to RF and combined with the Uplink signal from the LCX antennas after the amplification stages. The Cellular signal path is in the Uplink direction only, Signals are received, filtered and amplified before being fed to the operators’ base stations.
3.1. Tri-Band Combiner 60-214702 Simplified Arrangement Sketch
Base
60-214702 features dual redundant amplification stages in the Uplink bands so that in case of any single amplifier failure, complete signal loss would not occur in that path, allowing continued coverage. It also has a comprehensive alarm system (each amplifier module carries its own voltage­free contact alarm relay output). 60-214702 is powered from an AC supply at 110V.
Caution must be exercised when attempting to move or lift this unit as the gross weight of the unit is in excess of 90kg (200lbs)
