1. SAFETY CONSIDERATIONS
1.1 Earthing of Equipment
Cell Enhancers 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.
1.2
Electric Shock Hazard
Electrical shocks due to faulty mains driven power supplies.
Whilst ever potentially present in any electrical equipment, such a condition would be
minimised by quality installation practice and thorough testing at:
a) Original assembly
b) Commissioning
c) Regular intervals, thereafter.
All test equipment to 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.

1.3 RF Radiation Hazard
RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to
AFL’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 unterminated. 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.

1.4 Chemical Hazard
Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes used in
devices within equipment produced by Aerial Facilities 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 Aerial Facilities Ltd for disposal.
To return such equipment, please contact the Quality 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 AFL 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.
1.5 Emergency Contact Numbers
The AFL Quality Department can be contacted on:
Telephone +44 (0)1494 777000
Fax +44 (0)1494 777002

2. OVERVIEW/ SYSTEM DESCRIPTION
2.1 General System Description
The Weehawken tunnel radio system is designed to amplify various bands of radio frequencies,
in either channelised or band selective modes. All the hardware is built into standard 19” rack
mounted cabinets which have an environmental IP rating of 54. There is also a single, free
standing wall mounted amplifier which carries the whole signal network to the River Portal
area.
The system in this document will be described separately, as individual shelves (900MHz
Pager) and the various passive combiners, splitters and cross-band coupler shelves will also be
described in separate documents. Every active module in the entire system has a dedicated
alarm and these are series wired within the shelves to a relay which gives a volt-free output pair
for each shelf which is wired to a ‘krone-block’ termination in the rack cabinet.
