Chapter 3: Basic Connections
Supply Redundancy
Controllers must be divided by subgroups. Two links are required between controllers
Odd number of Expansion Boxes
• Each Expansion Box must have its own PSU (power supply)
• Each Expansion Box must have the highest PSU (PSU 120W) on it
• Consult the wiring diagrams to know how to connect the 24VDC from PSU
• Controller groups must be divided by subgroups of two Expansion Boxes and the last group must
have a subgroup of three Expansion Boxes
• The terminal ground (GND from 24VDC, Green color on diagram block) must be connected
between controllers on each link
Even number of Expansion Boxes
• Each Expansion Box must have its own PSU (power supply)
• Each Expansion Box must have the highest PSU (PSU 120W) on it
• Consult the wiring diagrams to know how to connect the 24VDC from PSU
• Controller groups must be divided by subgroups of two Expansion Boxes
• The terminal ground (GND from 24VDC, Green color on diagram block) must be connected
between controllers on each link
See the Quick start guide in document number 895-00692 (891-00516) for more information on both the
power supply wired with no supply redundancy and with supply redundancy
Preparing the Enclosures for Installation
Preparing the equipment before mounting it to the wall facilitates manipulation and ensures all parts are
ready to be installed.
Before You Begin
The following figures illustrate how to install the wires in the plastic enclosure. Wires are separated into
two groups: low voltage and high voltage.
NOTE: The use of rigid conduits up to 1 inch (25.4 mm) is allowed for the EDGE Main Controller. The use
of rigid conduits up to 2 inches (50.8 mm) is allowed for the EDGE 3-Slot Expansion Box and the
EDGE 6-Slot Expansion Box.
