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.
Connection to
Grounding Point
By connecting the ground terminal by drain wire to earth ground the switch and chas-
sis can be ground.
Before applying power to the grounded switch, it is advisable to use a
Note!
volt meter to ensure there is no voltage difference between the power
supply's negative output terminal and the grounding point on the switch.

Wiring a Relay Contact

The following section details the wiring of the relay output. The terminal block on the
EKI-7710 Series is wired and then installed onto the terminal receptor located on the
EKI-7710 Series.
