Choose a location to mount the cabinet. Make sure the location in a dry Step 1: area that is convenient to the branch circuit panel. Leviton requires that cabinet mounting hardware reach through the Step 2: drywall to wall studs or other suitable solid backing. However, properly sized struts and suitable hardware can also be used.

Line and Load Circuit 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.
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. Page 18...

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.
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 •...

General Requirements for Connecting any Device to Low Voltage Inputs Connect leads per wiring diagram as illustrated in the figures on the Step 1: following pages. Twist strands of each lead tightly (making sure that there are no stray Step 2: strands) and push firmly into appropriate plug connector location.

Momentary OFF input only 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.

Low Voltage Switches Plug the terminal block back into the cabinet with the screws facing Step 4: toward you and the wires exiting toward the side or top of the cabinet. Alternatively, the connector can be inserted with the screws parallel to the circuit board and the wires exiting toward you.
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.
Photocells The relay cabinet is capable of supporting the following types of photocells: Switched Photocell (On/Off, trigger point set at photocell). • 0-10V Photocell. • The configuration and behavior of your photocell is set via software (see the EZ-MAX Plus Programmer’s Guide for details). This section only covers installation. Photocell Wiring Connect leads per wiring diagram as illustrated in one of the following Step 1:...

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.
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: Determine the maximum available current of your supply, be it a PCD or Step 1:...

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.
