2.7.4 Wiring a Relay Contact. Advantech EKI-7710G-2CI, EKI-7710E-2C, EKI-7710G-2CPI, EKI-7710G-2CP

Electromagnetic Interference (EMI) affects the transmission performance of a device.

By properly grounding the device to earth ground through a drain wire, you can setup the best possible noise immunity and emissions.

By connecting the ground terminal by drain wire to earth ground the switch and chassis can be ground.

Note!

Before applying power to the grounded switch, it is advisable to use a volt meter to ensure there is no voltage difference between the power supply’s negative output terminal and the grounding point on the switch.
