Safety and Precautions
Observe all national and local electrical codes during installation
Mounting
The XIO device may be mounted in any orientation on a panel or a DINrail but must be in a position that allows clearance for wiring or
servicing.
WARNING!
Electrical Shock Hazard! Can cause severe injury, death or
property damage. Disconnect power supply and load power sources
before beginning wiring or making wiring connections to prevent
electrical shock or equipment damage.
Din Rail Mounting

Procedure
Position the base of the product level against the panel wall and mark
the wall to show the location of the corner holes.
The XIO I/O device mounts using four screws inserted through the
corners of the base. Fasten securely with four No. 6 or No. 8
machine or sheet metal screws.
Wiring
A removable terminal block is used to make all wiring connections to the
XIO device. Attach all wiring to the appropriate terminal blocks. All
wiring must comply with applicable electrical codes and ordinances, or
as specified in installation wiring diagrams (reference Wiring Method
section).
Users have the option to connect devices via daisy chain (using the
supplied removable terminal block) or connect devices via the bus
connectors (on the right (female) and left (male) side of the device).

NOTE!
Bussed installation of XIO Remote I/O is limited to a maximum of
five (5) modules
NOTE!
The RCC-1081 can also connect to the XIO power and
communication bus (edge) connectors, not to exceed a maximum of
five (5) modules on 1 bus.
NOTE!
If the bus connector method is being used, then the supplied 5position terminal block cannot be used when attaching additional XIO
devices.

WARNING!
Electrical Shock Hazard! Can cause severe injury, death or
property damage. Disconnect power supply and load power sources
before beginning wiring or making wiring connections to prevent
electrical shock or equipment damage.
NOTE!
For multiple controllers operating from a single transformer, the same
wire of the transformer secondary must be connected to the same
power input terminal in each controller.
The total power draw for all modules sharing the same transformer
must not exceed 100VA.
Wiring Method
Each terminal block can accommodate the following gauges of wire:
— Single wire: from 22 AWG to 14 AWG solid or stranded
— Multiple wires: up to two 18 AWG stranded
NOTE!
When attaching two or more wires to the same terminal, other than 14
AWG (2.0 sq mm), be sure to twist them together. Deviation from this
rule can result in improper electrical contact.
Table 5 Preparing wiring for terminal blocks

Procedure
Strip 1/2 in. (13 mm) from wires to be attached at one terminal.

Cut a single wire to 3/16 in. (5 mm). Insert the wire in the required
terminal location and tighten the screw.
If two or more wires are being inserted into one terminal location,
twist the wires together a minimum of three turns before inserting
them.
4
Cut the twisted end of the wires to 3/16 in. (5 mm) before inserting
them into the terminal and tightening the screw.
5
Pull on each wire in all terminals to check for good mechanical
connection.
BACnet Network
Wiring
A two-conductor shielded cable (reference Novar Part Numbers in Table
7) should be used to make the BACnet MS/TP Network Communications
connections from the Opus Executive Controller to the terminals on the
left side of the XIO device.
The BACnet network should originate from the main Opus Executive
Controller and connect to the XIO device with the supplied 5 position
XIO Family Installation Instructions

XIO Family of Remote I/O
terminal block. Multiple devices can be connected via daisy chain wiring
or bussed devices. Stubs or branches off the BACnet network are not
allowed.
In order to guarantee the network performance of each BACnet segment,
the BACnet network segments from the Opus Executive Controller
should contain only XIO device modules or other Novar approved
BACnet MS/TP devices.
NOTE!
Bussed installation of XIO Remote I/O is limited to a maximum of
five (5) modules
NOTE!
Network termination and/or biasing resistors should NOT be applied
to any Opus BACnet installation.
NOTE!
The baud rate for the XIO devices is fixed with 38400 baud.
NOTE!
Do not exceed the maximum recommended length (1200 M / 4000 ft.)
for any BACnet segment.
Setting BACnet
Address
Every XIO device comes from the factory set to a BACnet address of 0.
Each controller must be assigned a unique BACnet MAC address
(ranging from 4 through 254) in order for the Opus xcm Executive
Controller to be able to identify and communicate with it.
NOTE!
Address zero (0) cannot be used for controllers
XIO Family Installation Instructions
For the latest technical documentation, visit www.novar.com/manuals
13
XIO Family of Remote I/O
Users must set the unique BACnet MAC address for the XIO device
using the eight (8) DIP switches on the front of the module.
To set the BACnet address of an XIO device using the DIP switches:
Find an unused address on the MS/TP network to which the controller
connects.
Locate the DIP switch bank on the front of the Controller that is labeled
MAC Address.
With the XIO device powered down, set the DIP switches for the
BACnet address you want. Add the value of DIP switches set to OFF
(down) position to determine the MAC address (see Table 6). Example:
if only DIP switches 1, 3, 5, and 7 are in the OFF (down) position the
BACnet address would be 85 (1 + 4 + 16 + 64 = 85).

HOA Switch LED
Operation
For output modules equipped with HOA switches, the LED will rapidly
blink on and off if the HOA is in either the Hand (H), or Off (O)
positions to notify that the device is not operating in automatic control.
When the switch is in the Auto (A) position, the LED will be
continuously on or off, to match the status of the output relay coil.
In Opus software, the position of the HOA switches can be read while
viewing the points folder of the XIO device. Therefore, if the device is
overridden, you have a method of seeing that in the software. If needed,
alarms can be set up whenever loads are put into override.
