EARTH GROUND

2 Earth Ground

It is extremely critical for proper operation of the Reader that the earth ground be properly connected to avoid

damage by ESD. Connect the terminal labeled EGND to earth ground. This wire should not be connected to

the neutral, the cable shield, or any other wire except earth ground. See Figure 1 (PIV-Station Contactless

CHUID Reader shown) below.

• EARTH GROUND: A low impedance path to earth for the purpose of discharging lightning,

static, and radiated energy, and to maintain the main service entrance at earth potential. Consult local

codes for guidelines.

• ESD: Electrostatic Discharge (static electricity). The effects of a static discharge can degrade

or destroy semiconductor junctions for an electronic device.
