Safety Messages
DANGER
Turn off the main electrical disconnect switch prior to servicing any of the boxes.
Failure to do so might lead to serious injury or death.
Always use extreme caution when measuring voltage or performing procedures that require a
module to be powered on.
Electrostatic Discharge Prevention When Manipulating a Printed Circuit
Board (PCB)
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs
when electronic components are improperly handled and can result in complete or intermittent failures.
Always follow ESD on a PCB-prevention procedures when you remove and replace components. Ensure
that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring
that it makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame
to safely ground unwanted ESD voltages. To guard against ESD damage and shocks, the wrist strap and
cord must operate properly. If no wrist strap is available, ground yourself by touching the metal part of the
chassis.
For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and
10 megohm (Mohm).

Chapter 1: Introduction
Expansion Box Nomenclature
Expansion Boxes come with or without variable output modules (SSR). If there are no variable output
modules (SSR) in the Expansion Box (3-Slot Expansion Box, 6-Slot Expansion Box), the plastic enclosure
does not have an external heat sink on it.

6-Slot Expansion Box model without a Heat sink: EDGE 6-SLOT BOX or E6PN-_-____
The Expansion Box (3-Slot Expansion Box, 6-Slot Expansion Box) part numbering is defined as follows:
Power supply: On the 3-Slot Expansion Box, the power supply can be the 60W supply or the 120W
supply. On the 6-Slot Expansion Box, the power supply can be only the 120W supply
Variable output number is the number of variable output modules (SSR) installed in the Expansion Box
A heatsink comes with a variable output installation
If a 3-Slot Expansion Box is ordered, the number of the plug-in modules is limited to three
The following are two examples of Expansion Box names:
E3PH-1-C004
E6PH-2-AAAACE4
EDGE Variable Output (SSR)
This Variable Output was designed to efficiently and precisely control variable speed fans and multiple
dimmable light systems.
Features
891–00516 EDGE Wiring Diagram 13

Chapter 1: Introduction
• Three variable modes:
— Default mode
— Variable 1 Mode: for more accurate speed control of variable speed fans
— Variable 2 Mode : for enhanced control of dimmable lights.
NOTE: These modes can be set into the EDGE equipment configuration page with EDGE soft-
ware version 2.4.3. Mode selection is Default with existing configurations Default varia-
ble Mode will be Variable 1 for fans and Variable 2 for light with new configurations.
• Integration of the current sensing inside the module. No more need for the current sensor board
(045-11506).
• This new module needs a new cable harness. This one is not compatible with the previous version
(135-00021).
The EDGE variable output activates the output according to the voltage applied on the 0-10V input. The
control is done with a voltage between 3V to 10V. The proportion between the voltage input and the AC
output may change as per the mode set.
The EDGE variable output can be set in different mode according to the purpose. A voltage must be
applied between 2V and 3V during at least one second to activate a mode. Please note that these config-
urable modes are not yet supported by the EDGE system. By default, if no mode is set, the module will
work as a SSR of Crydom (CY7913).

voltage
Description
Default with
compensation
N/A Works like the Crydom SSR CY7913
Use compensation (see below)
Enhanced fan curve with
compensation
2.2 ±0.15V The curve is enhanced to give better control of the fan speed. Use
compensation (see below)
Light mode with
CRYDOM curve
2.6 ±0.15V This mode shall be used with light bulb (incandescent, ccfl, cfl and
led) control. Use Crydom SSR CY7913 curve.
Compensation
The compensation is used with fan. The compensation is working if the voltage is in the range of 190VAC
to 260VAC. A change on the AC supply voltage will be compensated to keep the fan speed (and CFM as
well). When compensation is activated, use a 240VAC curve in the EDGE controller.
Current Sensing
The current sensor is integrated in the EDGE Variable output. The current sensor also enables a feature
to detect “dead short” (error in wiring, L2 connected in the LOAD terminal per example or shorted LOAD).
If this event happens, the EDGE Variable output will shut off (to protect itself). A red LED on the module
will go steady ON to indicate the fault. To reset the fault, the 0-10V input must return to 0V.

Chapter 1: Introduction
Guidelines on the Ideal Location for Installation
Consider the environment, mounting recommendations, and clearance space to choose the ideal location
for your system.
Operating Environment
• To avoid exposing the system to harmful gases or excessive humidity, install the system and the
Expansion Boxes in a corridor or an area dedicated to electronic controllers.
• The ideal ambient temperature is between 20 °C and 25 °C (68 °F - 77 °F). The temperature should
not go lower than 0 °C (32 °F) and should not exceed 40 °C (104 °F).
• Ensure there is sufficient ventilation around the unit.
• Install the Expansion Boxes far from sources of vibrations and where they are not likely to get
bumped.
• Install the EDGE 4IN-2V-8DO in a cabinet
• The EDGE 4IN-2V-8DO temperature must be lower than 70°C (158°F) in the cabinet
IMPORTANT: If you are not planning on installing the system immediately, store the units in a cool dry
place.
Requirements for the Mounting Structure
Fix the enclosures into the supporting structure behind a drywall. If this is not possible, consider the addi-
tion of a wood frame on which the enclosure could be screwed.
Clearance Around the System Modules
The following minimum clearances must be respected around the EDGE enclosures.
891–00516 EDGE Wiring Diagram 15

Chapter 1: Introduction
16 891–00516 EDGE Wiring Diagram

Chapter 1: Introduction
Correctly Supporting and Routing Cables
Properly supporting and routing the cables helps avoid electromagnetic interference and wire damage.
Rigid conduits up to 1 inch (25.4mm) can be used for connection to the EDGE Main Controller. Rigid con-
duits of up to 2 inches (50.8mm) can be used for connection to the EDGE 3-Slot Expansion Box and to
the EDGE 6-Slot Expansion Box.
NOTICE
The heat sink on the back of the EDGE controller protrudes out the back of the
enclosure. This requires all connections to be at least 2 inches away from the wall in
order to connect into the enclosure.
AP/Cumberland recommends two installation possibilities:
• Use a 6 inch by 6 inch electrical trough installed at least 12 inches below the enclosure to pass the
connections through before connecting to the EDGE
• Offset the rigid conduits at least 2 inches from the wall with metal fixings
891–00516 EDGE Wiring Diagram 17

Chapter 1: Introduction
WARNING
It is important to respect the clearances above and below the enclosure to allow
airflow to the heatsink
Cable Connectors
NOTE: Nylon cable glands are permitted for cable or wire fastening.
WARNING
Use watertight compression cable glands rated IP54 for each cable used.
WARNING
Use silicone to seal the cable gland rated IP54 if more than one cable is use in the
same cable gland.
WARNING
The warranty is void if the product enclosures are not sealed correctly and the
installation does not respect the manufacturer recommendations.
WARNING
Ensure all cables enter through the bottom of the plastic enclosure. Do not make
holes on the top or on the sides of the enclosures. Be careful not to damage the
electronic cards located inside the enclosure when drilling at the bottom of the
enclosure.
NOTICE
The use of flexible tube with water and dust tight connectors at both ends is
acceptable.
Cable Support
Support the cables with clips or cable trays whenever possible to avoid damage at the connection points.
Cable Routing
NOTICE
Never run low voltage (24V and less) wires like communication wires, inputs or
sensors wires in the same conduit or underground trench as a High Voltage (Power)
wire.
When low voltage cables run parallel to high voltage cables (120/230/380 VAC or 24 VDC), place them at
a distance of at least 460 mm (18 inches) from each other to avoid electromagnetic interference. This
also applies to high and low voltage cables running through an underground trench.
If low voltage cables cross high voltage cables, ensure they cross at an angle of 90° to minimize electro-
magnetic interference.
18 891–00516 EDGE Wiring Diagram

Chapter 1: Introduction
WARNING
Do not use rigid conduits over 1 inch (25.4mm) for the EDGE Main Controller. Do not
use rigid conduits over 2 inches (50.8mm) for the EDGE 3-Slot Expansion Box and
the EDGE 6-Slot Expansion Box.
Cable Routing and Underground Trench
IMPORTANT: The same rules are applicable for the underground trench. The distance between the high
voltage and the low voltage must be at least 460 mm (18 inches) in the same cable tray or
conduit and between two different conduits in parallel.
WARNING
Follow the regulations and electrical code according to your area. Underground
trenches must be installed by a qualified contractor.
Grounding recommendations for the system
A correctly grounded system protects your equipment from electrical surges and spikes.
CAUTION
Each module must have its own ground connection from a common junction box.
Do not run the earth ground cable between the modules.
NOTICE
The ground resistance levels must comply with local and national electrical codes.
IMPORTANT: If outdoor connections are used, mount the enclosure as close as possible to the entry
point of the outdoor wiring.
IMPORTANT: An improper ground connection voids the system’s warranty.
Insert the rod into the ground until a few inches of the tip is left above ground level. Attach the cable to the
rod tip with an appropriate connector. Attach the other end of the cable to a breaker box or a junction box
near the main enclosure.
