Wiring The Alarm Contact; Wiring The Redundant Power Inputs - Weidmuller IE-SW-VL16-16TX Hardware Installation Manual

Wiring the Alarm Contact

The Alarm Contact consists of the two middle contacts of the terminal block on
Ethernet Switch top panel. You may 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. Ethernet Switch has lost power from one of
2. The PORT ALARM DIP Switch for one of
If neither of these two conditions is satisfied, the
Fault circuit will be closed.

Wiring the Redundant Power Inputs

The top two contacts and the bottom two contacts of the 6-contact terminal
block connector on Ethernet Switch top panel are used for Ethernet Switch 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 Ethernet Switch
top panel.
ATTENTION
Before connecting Ethernet Switch to the DC power inputs, make
sure the DC power source voltage is stable.
