22 Unison ® ERn Wall Mount Enclosure Installation Manual
Connect to Ethernet RJ-45
Network interface to the ERn enclosure is made through the RJ-45 connector (labeled
Ethernet) located on the left I/O board. Use the included Network Termination Kit to
terminate the incoming building wire.
Connect to Contact Inputs and Contact Outputs
The left I/O provides interface with external devices via contact closure on removable
pluggable connectors. Up to four contact inputs are available and can be configured for
either maintained or momentary operation as set in the Paradigm Architectural Control
Processor. Up to four contact outputs are also available and are preset for normally open
operation. Reference the Paradigm Architectural Control Processor Configuration Manual
for details on configuration.
Terminate Contact Inputs
Step 1: Remove the contact inputs removable screw terminal connector located on the
left I/O board. Each connector is labeled for installation convenience.
Step 2: Strip 3/16” (5mm) of insulation from the ends of each wire pair.
Step 3: Loosen the desired number of contact input screw terminals and related ground
screw terminals on the connector.
Step 4: Insert contact closure 1 into the terminal labeled “IN1” on the connector and
tighten the screw terminal.
Step 5: Insert the related ground wire for contact closure 1 into the terminal labeled
“GND” on the connector and tighten the screw terminal.
Step 6: Repeat for each contact input and ground wire pair (up to four total).
Terminate Contact Outputs
Step 1: Remove the contact outputs removable screw terminal connector located on the
left I/O board. Each connector is labeled for installation convenience.
Step 2: Strip 3/16” (5mm) of insulation from the ends of each wire pair.
Step 3: Loosen the desired number of contact output (normal open) screw terminals and
related ground screw terminals on the connector.
Step 4: Insert contact output 1 into the terminal labeled “N.O.1” on the connector and
tighten the screw terminal.
Step 5: Insert the related common wire for contact output 1 into the terminal labeled
“COM1” on the connector and tighten the screw terminal.
Step 6: Repeat for each contact output and common wire (up to four total).
N o t e : All Ethernet terminations must follow IEEE 802.3 and be terminated to the T568B
standard.
N o t e : Typical contact I/O wiring is color coded as follows: contact 1 - brown, contact 2 -
orange, contact 3 - yellow, contact 4 - green. All commons and ground voltages
are typically black or red.
