Weidmuller IE-MC-VL Series - Industrial Ethernet Media Converters - Manual (Page 8)

ATTENTION This product is intended to be mounted to a well-grounded
mounting surface such as a metal panel.
Wiring the Alarm Contact
The Alarm Contact is made up of the two middle contacts of the terminal block
on the Media Converter’s 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:
1. The Media Converter has lost power from one
of the DC power inputs.
OR
2. One of the ports for which the corresponding
PORT ALARM Dip Switch is set to ON is not
properly connected.
If neither of these two conditions occurs, the Fault
circuit will be closed.
Wiring the Redundant Power Inputs
The outer 2 contacts on left and right side of the 6-contact terminal block
connector are used for the Media Converter’s two DC inputs. Top and front
views of one of the terminal block connectors are shown here.

STEP 1: Insert the negative/positive DC wires
into the V-/V+ terminals.
STEP 2: To keep the DC wires from pulling
loose, use a small flat-blade screwdriver to tighten
the wire-clamp screws on the front of the terminal
block connector.
STEP 3: Insert the plastic terminal block
connector prongs into the terminal block receptor,
which is located on the Media Converter’s top
panel.
