2.1.1 Power Requirements
The Cobalt Controller requires an electrical supply voltage. See Technical
specifications for details. Use a regulated power supply connected to a suitable AC
power source that is capable of delivering these requirements. Do not apply power
until the entire system is wired and checked.
2.1.2 Installation Guidelines
• RF performance and read/write range can be negatively impacted by the
proximity of metallic objects. Avoid mounting the antenna within 15cm (6 inches)
of any metallic object or surface.
• Do not route cables near unshielded cables or near wiring carrying high voltage
or high current. Cross cables at perpendicular intersections and avoid routing
cables near motors and solenoids.
• Avoid mounting the controller near sources of EMI (electro-magnetic
interference) or near devices that generate high ESD (electro-static discharge)
levels.
• If electrical interference is encountered (as indicated by a diminished or reduced
read/write range), relocate the controller to an area free from potential sources of
interference.
• Conduct a test phase where you will construct a small scale, independent
network that includes the essential devices required to test your RFID
application. To avoid possible interference with other devices, do not initially
connect your RFID testing environment to an existing local area network.
• Always use adequate ESD prevention measures to dissipate potentially high
voltages.

Cobalt HF-Series RFID Antennas mount directly to the top of the Cobalt HF-Series
RFID Controller’s housing. The antenna is first attached to the RF port on the
controller and is then fastened to the controller’s housing using the two M5 screws and
matching spring lock washers included with each Cobalt HF-Series RFID Controller.
Use the provided 4mm hex key wrench to tighten both M5 screws.
