FAULT: The two sets of relay contacts of the 6-pin terminal block connector are used to detect user-configured events. The two wires attached to the Fault contacts form an open circuit when a user-configured event is triggered. If a user-configured event does not occur, the Fault circuit will be closed.

Wiring the Redundant Power Inputs

The EDS-728/828 has two sets of power input—power input 1 and power input

2.The top two contacts and the bottom two contacts of the 6-pin terminal block connector on EDS’s top panel are used for EDS’s two digital inputs.

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 EDS-728/828’s top panel.

Wiring the Digital Inputs

The EDS-728/828 has two sets of digital input—DI 1 and DI 2. Each DI comprises two contacts of the 6-pin terminal block connector on EDS’s top panel. The terminal block is also used for EDS’s two DC inputs. Top and front views of one of the terminal block connectors are shown here.

STEP 1: Insert the negative (ground)/ positive DI wires into the ┴/I1 terminals.

STEP 2: To keep the DI 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 EDS-728/828’s top panel.
