Grounding the Ethernet Switch
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from
the ground screw to the grounding surface prior to connecting devices.
A 4 mm
2
conductor must be used when connection to the external
grounding screw is utilized.
ATTENTION
This product is intended to be mounted to a well-grounded
mounting surface, such as a metal panel.
Wiring the Relay Contact
The Relay Contact consists of the two middle contacts of the terminal
block on the IE-SW-VL05/08M series top panel. Refer to the next
section for detailed instructions on how to connect the wires to the
terminal block connector, and how to attach the terminal block
connector to the terminal block receptor.
In this section, we explain the meaning of the two contacts used to
connect the Alarm Contact.
FAULT:
The two middle contacts of the 6-
contact terminal block connector are used to
detect both power faults and port faults. The
two wires attached to the fault contacts form
an open circuit when:
A relay warning event is triggered.
OR
The IE-SW-VL05/08M is the Master of a
Turbo Ring, and the Turbo Ring is broken.
OR
There is a start-up failure.
If none of these three conditions is satisfied,
the fault circuit will remain closed.
Wiring the Redundant Power Inputs
The top two contacts and the bottom two contacts of the 6-contact
terminal block connector on the IE-SW-VL05/08M series top panel are
used for the two DC inputs. Top and front views of one of the terminal
block connectors are shown in the following figures:
