Chapter 2: Basic connections
5. When the plug-in relay is correctly aligned, apply pressure on the middle part of the plug-in relay
until it is locked in place.
6. Wire the new plug-in relay.
7. Reconnect the main supply voltage, and ensure all equipment turns on correctly.
NOTICE
For the terminal blocks connected on the power relays, use a tightening torque
from 0.7N*m (6.2lbf*in) to 0.8N*m (7lbf*in) to fasten a wire gage from 10AWG to
14AWG. 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 gage from 16AWG to 18AWG.
DC network and power supply redundancy
Three possible configurations are available: No supply redundancy, supply redundancy with an odd
number of Expansion Boxes, supply redundancy with an even number of Expansion Boxes. Look at the
paragraph
Equipment wiring rules for backup and failsafe operation, page 21 to understand the supply
redundancy concept. In the supply redundancy concept, the subgroup concept is very important. Depend-
ing on the DC network chosen, select the right wiring diagram for installation.
NOTICE
The recommended installation is 16 AWG 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 is
18 AWG 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
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.
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.
