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.
Figure 2.16 Grounding Connection
By connecting the ground terminal by drain wire to earth ground the device and
chassis can be ground.

Wiring a Relay Contact
The following section details the wiring of the relay output. The terminal block on the
EKI-6333AC-4GP is wired and then installed onto the terminal receptor located on
the EKI-6333AC-4GP.
Figure 2.17 Terminal Receptor: Relay Contact
The terminal receptor includes a total of six pins: two for PWR1, two for PWR2 and
two for a fault circuit.
Caution!
Do not block air ventilation holes.
Note!
Before applying power to the grounded device, 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 device.
