2.0 INSTALLATION
The installer of this radio equipment must ensure that the antenna is located or pointed such
that it does not emit RF field in excess of Health Canada limits for the general population; consult
Safety Code 6, obtainable from Health Canada’s website www.hc-sc.gc.ca/rpb.
2.1 Unpacking the unit
Carefully remove the equipment from its packing material and set it on a solid surface, such as a table or
desk. If it appears damaged in any way, notify the carrier, and keep all packing materials for inspection by
the carrier’s agent.
2.2 Operating Environment
The AP5857 is designed to operate in an outdoor environment at temperatures ranging from –40 to +60°C
(-40 to +140°F). As with all electrical equipment operation outside specified temperature ranges will
accelerate the deterioration of components.
2.3 Power Requirements
The equipment has an auto-ranging internal power supply, which allows it to be powered from the 35-90VAC
60Hz power tap on the strand. This power tap must capable of delivering a minimum of 27 watts per AP5857.
Note: Most power taps are current limited and will shut off when the current gets above a certain level. Care
must be taken to ensure that under the worst case conditions of elevated temperature and long lines between
power supply and AP5857, that the AP5857 can receive enough current without tripping the overcurrent
switch and shutting off the power.
2.4 Radio Mounting
Pipe/Pole Mounting
With the pipe or pole mount option, the Strand Radio may be mounted vertically on a wooden or metal utility
pole up to 36.8 cm (14.5") diameter or a pipe with diameter greater than 10 cm (4"). If the pole or pipe mount
option is selected with the NORMAL configuration (which includes an internal antenna), the radio must be
oriented vertically. Ensure the unit is oriented so that the text on the label is upright. This puts the internal
antenna in the correct orientation which is horizontal polarization, 60 Deg horizontal beamwidth and 30 Deg
vertical beamwidth. Mounting the radio with a non-vertical orientation will prevent proper operation of the
system.
Step 1. An adapter bracket is used to attach the Strand Radio to the pole clamp. Use a ½” wrench and the
four hex-head bolts with lockwashers to attach the adapter bracket to the pole clamp. The bolts go through
the pole clamp holes, through the outside of the adapter bracket, and are secured on the inside of the bracket
with the lockwashers and nuts. This assembly can then be attached to the Strand Radio baseplate using the
two sets of four screws and lockwashers. Confirm that the radio is oriented with the labels reading
right-side-up.
