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 IMC-101G’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

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 IMC-101G has lost power from one

of the DC power inputs.

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 top two contacts and the bottom two contacts of the 6-contact terminal

block connector on the IMC-101G’s top panel are used for the IMC-101G’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, respectively.

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 IMC-101G’s top

panel.
