5 Finding the best location for the units
Follow the guidelines below to find the best place to mount the terminal:
• Place the units by an easily accessible power outlet.
• Do not place communication cables near a source of electromagnetic radiation or radio interference
such as power lines, large machinery, etc.
• Do not place the units where exposed to extreme hat or cold, water, steam, violent vibrations or
strong electromagnetic radiation including high voltage power lines and electrical equipment.
• The installation location selected should be as far as possible from sources of electrical reference
such as power equipment, computers, motors, pumps, etc.
• Maintain at least a one meter distance from computer displays.
• Keep the cable by at least 30 cm away from any other cable.
• Use a power adaptor dedicated to the proximity unit. Make sure the adapter carries a safety
recognition marking such as UL, CSA or CE.
• If you are installing more than one
Synel proximity reader, make sure the readers are installed at a
distance of at least 50 cm from one another (5 times the unit reading limit).
• Use a linear power supplier and not a switching power supplier which generates an electromagnetic field that shortens the reading range.
It is advisable to connect an independent power supplier to the reader.
• Make sure there are no metallic materials surrounding the unit.
• When mounting on a drywall (gypsum wall), make sure that there are no rear metallic
reinforcements to the wall.
• Make sure that it is safe to drill into the wall at the desired location.
