Selection of a Mounting Location

Choosing a mounting location for your cabinet is critical to the overall success and
ease of installation. Each style of cabinet has its own unique wiring requirements
which must be observed. Please review the next few pages, which describe and
illustrate these requirements.

Suggested Mounting Heights

Although successful operation is completely independent of mounting height, the
suggested mounting heights below were selected to locate the cabinet at a
reasonable and accessible working height.

Cabinet Suggested Mounting height to bottom of cabinet

8-Relay Cabinet 53" (1,359 mm)

16/24-Relay Cabinet 32" (826 mm)

Environmental Considerations

• Cabinets generate heat (see table below). Make sure they are mounted in a
climate controlled space where the temperature will be 0-40o C (32-104oF) or
20-30o C (68-86oF) if used as Emergency Lighting Power Equipment.

• Reinforce the wall for strength as required for weight and local code.

• Clearance on left and right side of the panel should be maintained at 1 1/2" or

greater.

• Relays will click while in operation. Locate the panels where audible noise is
acceptable.

Preferred Areas for Conduit Entry

Your relay cabinet has been designed for easy installation, with a variety of installation
options. Please pay close attention to the “allowed” and disallowed” areas for conduit
entry. Disallowed areas are areas where conduit entry is impossible due to physical
limitations or code limitations. These areas are clearly marked in the illustrations that
follow. Each cabinet style has designated areas for low voltage and line voltage
conduit entry. You must adhere to these requirements to ensure a successful
installation and continued code compliance.

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.

Page 12

Line Voltage

Page 14

Line Voltage and Control Power Termination

Since the panel is fed from multiple circuits, locate each one
and lock-out each feed in the OFF position.

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.

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.

LINE VOLTAGE

Each relay panel has areas dedicated for line voltage wiring and similar orientation.
The figures on the next few pages illustrate line voltage wiring.

30-Amp Relay

Mounting Screw

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:

LINE VOLTAGE

Step 1: Locate the appropriate location for the relay card

Step 2: Align the connector from the relay card with the relay bus board and

gently push the two together.

Step 3: Once firmly seated, use a phillips screwdriver to tighten the mounting

screw.

EZ-MAX Plus Installation Guide Page 17

Line Voltage and Control Power Termination Line and Load Circuit Wiring

If you need to remove the installed relay cards that shipped
from the factory, remove the shipping screw located near the
connector and discard. This screw is only required for
shipping and not for installation.

MISWIRING THE RELAY MODULES WILL
CAUSE DAMAGE TO THE RELAY MODULE,
THE RELAY CABINET, AND POSSIBLY
OTHER SYSTEMS!

When driving secondary contactors, EMF may
induce significant noise which may cause some
units to reset. Installation of MOV may be
required. Please contact Leviton support for
additional details.

Wiring the Relays

Step 1: Connect the line (feed/circuit breaker) side of the circuit to the “input”

terminal(s) on the relay card.

Step 2: Connect the load side of the circuit to the "output" terminal(s) on the

relay card.

Step 3: Please note that relay card terminals accept the following wire sizes:

Low Voltage Control Wiring

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. Contact our technical services
department with any further questions.

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

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 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.

LOW VOLTAGE

EZ-MAX Plus Installation Guide Page 25

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:

Connector Type Wire Size and type Torque

Switch Inputs 14-24 AWG, Stranded 2 in-lb.

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
jumpers.

Input Power Requirements

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
Inputs

Step 1: Connect leads per wiring diagram as illustrated in the figures on the

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

the front and the wires coming out of the connector toward the top of
the cabinet.

EZ-MAX Plus relay panels support a variety of low voltage switch types such as:

• 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.

Each Input has a multi-position screw terminal with various positions. The terminal
can be pulled off its base for ease of wiring. One possible pinout is shown below.

Please remember to verify the function of each pin as labeled on the product with the
device being wired to ensure that it is wired correctly.

Figure 16: Discrete input terminal labels and their meanings —applies to all

Leviton products

By default, the “IN” or the “ON” terminal is expecting +V to trigger as would be typical
with many styles of low voltage switches. If a connection to common is required, it
requires some jumper and software reconfiguration. For more information on this
topic, please see “Input Trigger-What Determines an “ON”” on page 26.

Connecting to a Low Voltage Input

Step 1: Strip each wire from your device and tightly twist the wires together.
Step 2: Insert the wires from the device into the connector on the relay cabinet

in the appropriate location.

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.

Occupancy Sensor Wiring

Step 1: Connect leads per wiring diagram below.

Jumper must be in +24V position to
power digital stations

required at the two ends of the Luma-Net run. The termination can be
accomplished on the Luma-Net connector with a jumper wire as shown
below. Termination can also be accomplished on the control board by
jumpering the 2 pin header to the left of the Luma-Net connector.

PG

The emergency input is set from the factory as a level 2
priority, only overridable by the internal bypass switch.

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.

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,
in an emergency state.

If the emergency input changes from closed to open (low to high), the relays will
return to their previous states.

Appendix B

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.

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.

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.

EZ-MAX Plus Installation Guide Page B-1

• 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.

Power Considerations for Control Systems

One Unit Load = 25mA = .025A

Power Supply's
Available Unit Load

The sum of all devices connected to all power output
terminals can not exceed the Maximum number of Unit Loads
available in the PCD or supply.

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.

Make sure that you use the correct table!

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:
