Hardware grounding considerations
• An effective electrical ground connection– Minimizes the possibility of interference– Reduces the risk of equipment damage– Eliminates electrostatic buildup– Helps protect personnel
• The best grounding option available when installing the reader is earthing
• A ground loop occurs when there is more than one ground connection path between two pieces of equipment

Power sourcing considerations
• Battery• UPS• Power distribution• Power-over-Ethernet• Considerations for power supply installation
– Ensure that the supply voltage of the reader is within specification
– Use single point grounding– Use recommended cable with overall shielding – Run the cable in an individual conduit– Organize all the cables and permanently mount them
with wire ties and mounting brackets

Installation of electrical cables
• Consideration for cable installation– Use cables that are labeled by the manufacturer– Avoid exposure to electromagnetic energy – Use labels to identify cabling parts – Ensure orderly layout of cables– Apply a protective sealing where the cable has been cut – Place earth bars in front of panels and junction boxes– Connect the field equipment to the PE system through
the cable
• Junction boxes• Wireless network installation

Hardware safety considerations
• Environment– Humidity, condensation, temperature changes
• Safety– Enclosures protect equipment from damage and
safeguard the people who work nearby

RFID system on a conveyor (con’t)
• Considerations for installing conveyor systems– Control the movement of the conveyor that is based on
tag reads – Configure antennas to cover all locations– Provide sufficient power to the reader– Use read-only tags

RFID system on a dock door (con’t)
• Dock door requirements– A high-powered UHF system– Sufficient power to the antennas in the interrogation
zone– A reader set to constantly look for tags
• Setting up the dock door portal– Decide on the coverage area and the number of
antennas to use– Determine the location for antenna placement– Install the antennas– Perform a path loss contour mapping

RFID system on a shelf (con’t)
• Considerations for installing portal systems– Portals need careful synchronization with other RFID
readers or RF devices– Readers need to be configured to read as many tags as
possible– Portals need to be integrated into the network– Reader antennas need to be properly placed to avoid
interference – Readers need to be protected from environmental
conditions
