IDTeck – iCON 1 DOOR ACCESS CONTROLLER
4.2.2 UNBALANCED ELECTRIC POTENTIAL
Symptoms Seen if AC Input Electric Potential is Unbalanced

Communication shut down within controllers.
 Error of controller operation.
To prevent the unit having unbalanced electric potential, use a same power source for all the
controllers.
Symptoms Seen if DC Input Electric Potential is Unbalanced
 The data read in the reader and sent to the controller gets damaged.
In order to prevent the unit having unbalanced electric potential of the DC inputs, use the same power
source or use a common GND (-).
4.2.3 EARTH GROUND
The
NESS - iCON100
must be properly grounded to the earth for safety reasons and to prevent
damage to the microelectronics due to electrostatic discharges. The
NESS - iCON100
must be
connected to earth ground either through conduit, if used, or through a separate ground wire.
On-site connection to earth ground can be accomplished through:
- an earth ground rod, a metal water pipe, the building’s structural steel, or a ground grid.
 How To Ground
 Make connection with grounding bar or pipe of the building.

Connect shield of data and communication cable.
 Grounding must be done in one direction only otherwise it reverses to the device causing fatal
damage.

The grounding for communication cable must be less than 10 Ω .
