Relay Cabinet Mounting
Mounting Provisions and Dimensions
Step-by-step Mounting Instructions
Step 1:
Choose a location to mount the cabinet. Make sure the location in a dry
area that is convenient to the branch circuit panel.
Step 2:
Leviton requires that cabinet mounting hardware reach through the
drywall to wall studs or other suitable solid backing. However, properly
sized struts and suitable hardware can also be used. The load must be
evenly distributed to the anchors without exceeding the recommended
anchor limit. Using drywall screws directly through drywall without a
stud is not acceptable. Make sure that adequate support at all points is
provided. For fully loaded cabinet weights, see “Product Specifications
and Capabilities Chart” on page 3.
Step 3:
Remove the cover. Some cabinets may also require the removal of data
and/or grounding wires. Make sure that this occurs prior to removal of
the door and that they are reconnected when reinstalling the door. On
cabinets with hinges, simply lift the door off the hinges. On cabinets
with screws, remove the cover screws. Appropriately store the cover for
future use.
Step 4:
Before you proceed any further, see “Preferred Areas for Conduit Entry”
on page 8. This section shows the location of the mounting holes and
allowed conduit entry locations for each cabinet type.
Step 5:
Verify which end of the cabinet is the top before you attach the cabinet
to any surface. Some cabinets have “up” arrows to indicate the top end.
Step 6:
Attach the cabinet to its prepared mounting surface as appropriate.
Step 7:
Cut, punch, or remove knockouts for the desired conduit openings. Pay
special attention to any disallowed areas for conduit entry.
Step 8:
Pull all wire, both line and low voltage as appropriate.
Step 9:
Carefully and completely remove any dust, debris, metal particles, etc.
from inside the cabinet in preparation for wire termination and eventual
power up.
Step 10: Proceed to “Line Voltage and Control Power Termination” on page 15.

Line Voltage and Control Power Termination
Overview of Power Wiring - Feed\Line
Wiring
Wiring is simple. All you need is the following:
•
Dedicated circuit for control power - Hot, Neutral and Ground
•
Individual load wires leaving relays, output circuits.
Since the panel is fed from multiple circuits, locate each one
and lock-out each feed in the OFF position.
All cabinets have ample area for conduit entries for feed, load, and control wiring.
Ensure that conduit entry is only in the allowed locations. See “Preferred Areas for
Conduit Entry” on page 8 for permitted locations.
Each relay panel has areas dedicated for line voltage wiring and similar orientation.
The figures on the next few pages illustrate line voltage wiring.

EZ-MAX Plus relay cabinets have multiple relay circuits of a specific type depending on
the cabinet model. For details of the different relay types, their capacities, and
permitted wire sizes, please see “Wire Sizes and Capacities for Relays” on page 18.
Testing the Circuits
Verify that all load and feed connections have been made before you attempt to
connect any circuit to a relay. Test each circuit in the cabinet by following this
procedure:
Step 1:
Turn off the breaker feeding the circuit
Step 2:
Ensure that all connections and wiring between the relay cabinet and
the circuit breaker panel are complete
Step 3:
Ensure that all connections and wiring between the relay cabinet and
the load are complete.
Step 4:
At the relay cabinet, connect the feed(s) for relay #1 to the load for
relay #1 with a wire nut or other appropriate means.
Step 5:
Turn on the circuit breaker to energize the circuit.
Step 6:
Resolve any mis-wiring, shorts, etc. for the connected circuit.
Step 7:
Repeat the above steps for all circuits in all relay panels for your
system. When all circuits have been tested, disconnect all Lines from
Loads and proceed to the next section.
Installing Relay Cards
On several relay cabinet models, the relays are removable. If you have one of these
cabinets and need to add or remove relay modules, please follow these instructions:

Your relay cabinet requires a specific power circuit for the control electronics. Leviton
recommends that this power circuit be dedicated specifically and used only for power
to the control electronics.
If any Emergency Circuits are fed or controlled from this
panel, it must be located electrically where fed from a UPS, a
generator, or other guaranteed source of power during
emergency and power outage situations.
To connect your relay cabinet’s control electronics to power, please follow these steps:
Step 1:
Connect the relay cabinet to the circuit panel using conduit.
Step 2:
Remove all cuttings and dirt.
Step 3:
Run a dedicated circuit from the circuit panel or distribution panel to

Low Voltage Control Wiring
Once the power wiring has been completed, you can begin the control wiring. Control
wiring can be divided into two categories: analog and digital. Remote relay panels
only support analog control inputs.
Control Overview
•
Low Voltage momentary or maintained through a discrete input.
•
Momentary 2-Pole On/Off through a discrete input.
•
Photocell 0-10VDC or Switched through a discrete input.
•
Occupancy sensor through a discrete input.
•
Dry Contacts through a discrete input.
•
Digital control inputs (See “Wiring the Phoenix Connector” on page 40).
Please see “Product Specifications and Capabilities Chart” on page 3 for more
information on the quantity and types of inputs available for each cabinet. All inputs
(except network inputs) support every type as shown above.
The specific wiring requirements for each input type are discussed on the following
pages.
Each product (and in some cases each model of a
product) has a slightly different layout at the terminal
blocks. The specific function of each terminal is labeled on
the circuit board adjacent to the terminal blocks. When
wiring the inputs, verify that you are connecting the
correct wire to the correct terminal based on function,
even if it deviates from what is shown in this
documentation.

LOW VOLTAGE
The Leviton EZ-MAX Plus relay products are simple yet powerful, and can be operated
by multiple control sources. Control input to a relay cabinet can be any combination of
the following:
Low Voltage Control Wiring
Control Overview
Control Wiring Termination
This section gives instructions for terminating all types of low voltage inputs.
•
Leviton recommends minimum 18AWG stranded wire for all low voltage wiring.
•
Terminate all control wiring directly to the terminal blocks on the printed circuit
board. Use a small 1/8-in. flat screwdriver on these terminals.
•
Terminal blocks are 2-part terminals and can be removed for ease of termination.
When reinstalling them make sure they are plugged in the correct direction
according to the way they were wired.
•
All control wiring shall be considered Class 2.
•
Use control wire type and size as specified below:

Figure 14: Control Wire Type and Size
Input Trigger-What Determines an “ON”
Each of the low voltage inputs can be triggered by either the supply of voltage or a
connection to common. When voltage is supplied to an input indicating a change of
state, we call this “pulling up the input” or “active high.” When a connection to
common triggers the input, causing a change of state, we call this “pulling down the
input” or “active low.”
By default, all inputs are active high (that is receiving voltage to trigger). Active High
inputs must not exceed a nominal +24VDC and must be above +9vdc. Active Low
inputs must connect to the same common at the same potential as the cabinet.
To change from an active high input to an active low input, the polarity jumper must
change position. There are several illustrations which show the location of these

The relay cabinet has a finite amount of power which it can supply to connected
devices. This topic is discussed in detail in “Power Considerations for Control Systems”
in Appendix A. Please make sure that you do not exceed the amount of available
peripheral power, or damage to your relay cabinet or connected devices may occur.
Page 26
General Requirements for Connecting any Device to Low Voltage

following pages.
Step 2:
Twist strands of each lead tightly (making sure that there are no stray
strands) and push firmly into appropriate plug connector location.
Step 3:
Tighten the screws on the plug connector—making sure that no bare
conductor is showing.
Step 4:
Plug the connector back onto the control module with the screws facing

•
Momentary: provides momentary contacts, triggering alternating On/Off
actions.
•
Maintained: triggers On action when connection is made, Off action when
removed.
•
Momentary On/Off with On & Off terminals provided: provides momentary
connection to the “On” terminal to trigger an On action, momentary connection to
the “Off”. Used with single pole double throw center off (SPDT-CO) switches.
•
Momentary On/Off with only “IN” or “ON” terminal: used with 2-pole
center off switches and must be used in conjunction with compatible switch input
kits to convert from a 1 terminal to a 2 terminal input.
LOW VOLTAGE
EZ-MAX Plus relay panels support a variety of low voltage switch types such as:
Each Input has a multi-position screw terminal with various positions. The terminal
Switch Inputs and DMX Connectorcan be pulled off its base for ease of wiring. One possible pinout is shown below.

Occupancy Sensors
One of the control input types that your relay cabinet can accept is Occupancy
Sensors. When using an occupancy sensor, the cabinet is expecting a DC voltage
between +9V & +24V to trigger an occupied state, or a floating input to indicate an
unoccupied state. The specific function of what happens in each of these states is set
via software configuration. This section only deals with connecting your Occupancy
Sensor to your relay cabinet. See the EZ-Max Plus Programmer’s Guide for more
information on programming your inputs.

Emergency
Inputs and Outputs
The control card has both an emergency input and output. The input can be driven by
a contact closure such as one from a fire alarm or by a low voltage signal capable of
sinking 5 mA (3 - 5 volts is emergency off and 0 - 2 volts is emergency on).
Emergency output has a common contact and both NO and NC contacts. In the nonemergency state, the NO contact is closed. If the emergency input is activated
(closed) or if power is interrupted to the relay cabinet, the NC contact will be closed.
PG
Extended information available in the EZ-Max
Plus Programmer’s Guide.
If it is desirable, the output of one cabinet can be connected to input of another
cabinet. In this case, connect the commons of both input and output together and
connect the NC output contact to the emergency signal on the input connector as
shown in the figures on the following pages.
Each relay can be configured to go on, off or to no change via the setup menu when
in an emergency state.
If the emergency input changes from closed to open (low to high), the relays will
return to their previous states.
EMERGENCY
The emergency input is set from the factory as a level 2
priority, only overridable by the internal bypass switch.

Power-Up and Installation Verification
Checklist
Prior to the application of power to your relay cabinet, all of the following steps must
have been successfully executed.
Inspect each relay load wiring for incomplete termination
Inspect each relay’s load wiring for terminals not completely tightened
With each relay in the “off” position, check for voltage between the Line & Load
terminals; there should be none.
Inspect all low voltage wiring and ensure that it is complete.
Inspect control power wiring, ensure that it is complete.
Confirm that any unused supply wires on the control power transformer have
been suitably capped.
Confirm that all connected load wiring between the relay panel and it’s load has
been completed.
Confirm that wiring between the cabinet and all low voltage devices has been
completed.
Apply power to the cabinet.
Confirm that the cabinet boots properly and returns to the status “normal” screen.
Set the Time & Date from the menu.
Update system software with the latest available software from the website, if
appropriate.
Proceed to panel programming.

Appendix B
Power Considerations for Control
Systems
The control system should be carefully planned to take these important issues into
consideration:
•
Power Supply for connected devices.
•
Wire Size for Power Runs.
On systems where full factory drawings have been provided, our Applications
Engineering department has already managed these calculations for you so you only
need to follow the instructions on the system drawings. However, on any installation
where factory drawings were not provided, the information contained within this
guide must be followed to ensure that all of your devices operate properly and
without failures or complete in-operability.
This section of the document contains information that
applies to many Leviton products and is not necessarily
limited to the product that is primarily included in this
manual. There may be information in this chapter which is
not relevant to your particular installation. If you have
questions about ANY information contained in this manual,
please immediately contact our Technical Services
Department prior to proceeding with installation.
Terminology
Please review these definitions that are used throughout this section:
•
Power Supply or Supply: references a device that supplies power to other
devices.
•
Power Control Device (PCD): refers to a device that controls power. The
EZ-MAX Plus relay panel is an example of a devices in the Leviton product line
that controls power. PCD’s supply a certain amount of power to connected low
voltage control devices.
•
Control Devices or Low Voltage Control Devices or Device: these terms all
refer to control devices that connect to a Power Control Device (PCD). These
devices could be simple low voltage switches, Occupancy Sensors, or D8000
control stations.
•
Luma-Net: is one of our network lighting control protocols. Luma-Net is an
RS-485- based control protocol used by EZ-MAX PLus Digital Control Stations,
D8000 and D4200 control devices. Many of our PCD (Power Control Device)
products have a direct data connection for a Luma-Net device. All Luma-Net
Control Devices require power in one form or another. This power generally
accompanies the data wires.
•
Unit Load: one (1) Unit load is defined as 25mA, or 0.025A. It is an arbitrary
definition by Leviton and was created to simplify power calculations.
EZ-MAX Plus Installation Guide
Page B-1
Power Considerations for Control Systems
Power Requirements and Maximum Run Length
Each Control Device used in your system has a different load (draw) and each PCD
can support a different total load (supply.) There are logical steps for determining the
total load of your network and verifying that the supply is sufficient:
Step 1:
Determine the maximum available current of your supply, be it a PCD or
other Power Supply. Convert this to the maximum number of Unit Loads
if necessary.
Step 2:
Calculate the sum required load of each Control Device, expressed in
unit loads
Step 3:
Verify that the Sum from Step 2 <= the maximum available power from
your supply in Step 1.
If this verification fails (the Sum of required loads is > than the available supply) you
can either use an external power supply or reduce the number of control devices. Or,
contact our Technical Services department for help.

Power Considerations for Control Systems
Power Wire - Run Length
The maximum total run length of each segment is a function of the total number of
unit loads. A run becomes too long when the voltage drop, due to wire size and run
length, increases to a point where the station does not have sufficient voltage to
operate. The maximum run length, in feet, based on the total number of unit loads is
shown below:
(2) Tables are provided, (1) @ 12VDC and (1) at 24VDC.
Make sure that you use the correct table!
