By connecting the ground terminal by drain wire to earth ground the switch and chas-
sis can be ground.
2.5.4 Wiring a Relay Contact
The following section details the wiring of the relay output. The terminal block on the
EKI-5729PI & EKI-5624PI is wired and then installed onto the terminal receptor
located on the EKI-5729PI & EKI-5624PI.
Figure 2.9 Terminal Receptor: Relay Contact for PoE models
The terminal receptor includes a total of six pins: two for PWR1, two for PWR2 and
two for a fault circuit.
2.5.5 Wiring the Power Inputs
There are two power inputs for normal and redundant power configurations. The
power input 2 is used for wiring a redundant power configuration. See the following
for terminal block connector views.

To wire the power inputs:
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.

Warning! Power down and disconnect the power cord before servicing or wiring
the switch.
Caution! Do not disconnect modules or cabling unless the power is first switched
off.
The device only supports the voltage outlined in the type plate. Do not
