Chapter 3: Basic Connections
NOTICE
The recommended installation wire gauge is 16 AWG (diameter of 1.29mm or cross
sectional area of 1.30mm
2 ) for the power supply wires at a length of 300 meters (1000
feet). At the minimum gage (18AWG) for the power supply wires, the maximum wires
length is 150 meters (500 feet) . The recommended installation wire gauge is 18 AWG
(diameter of 1.02mm or cross sectional area of 0.82mm 2 ) for the communication wires at a
length of 1200 meters (4000 feet). The cable must be twisted pair and shielded. The EDGE 3-Slot
Expansion Box and the 6-Slot Expansion Box can supply up to 5 amperes to the modules.
WARNING
Installation must only be performed by qualified service personnel.
WARNING
When choosing the supply redundancy option, only one Expansion Box must
supply the Main Controller, and controller groups must be divided by subgroups of
two Expansion Boxes plus one group of three Expansion Boxes if the number of
controller is odd
WARNING
When choosing the no supply redundancy option, do not forget to wire the GND
(GND from 24VDC, green color on diagram block) between each controller.
NOTICE
For the small terminal blocks used for inputs and low voltage outputs, use a
tightening torque from 0.5N*m (4.43lbf*in) to 0.6 N*m (5.2lbf*in) to fasten a wire.
Connecting a Module to the Communication Network
The communication bus enables communication between the EDGE Main Controller and the EDGE mod-
ules (terminal A and terminal B on the Automation network or the Safety network). There are two commu-
nication networks available. One of them serves as a backup network.
1. Locate the terminals Automation or Safety on the module you want to connect to the EDGE 3-Slot
or 6-Slot Expansion Box or EDGE 4IN-2V-8DO.
NOTE: You should always use the Automation network, unless you have redundant main controls.
2. Connect the wires from the module to the EDGE 3-Slot or 6-Slot Expansion Boxes or EDGE 4IN-2V-
8DO.
IMPORTANT: Make sure to connect same identifications together and use the same network from
one side to the other.
IMPORTANT: The communication network must be installed in a daisy chain topology. Consult the
wiring diagrams to see the maximum cable distance according to the wire gauge.
