Revision A - April 2005
Overview
Inspection
Carefully unpack the relay cabinet, and inspect to make sure there has been no hidden
shipping damage. Report all damage to the freight carrier who delivered the system. Claims
for damages are filed with the freight carrier as all freight is shipped FOB Tualatin, Oregon.
In case of damaged components, your EZ-MAX relay cabinet can be serviced in the field with
factory replacement parts.
Description
The compact physical design of your EZ-MAX Relay cabinet takes up a minimum of wall space.
The product is only designed for surface mounting. The properties of your cabinet are as
follows:
Cabinet Properties
Some of the relay features are:
•UL & cUL Listed for use in USA and Canada
•Compliant with NEMA requirements
•Easy to install
•Quick & Easy to Configure
The control portion of the relay cabinet employs all digital circuitry for accuracy and for
minimum wiring requirements between the relay cabinet and its control systems.
Control Overview
The Leviton EZ-MAX relay Cabinet uses an intelligent central control card (Digital Main Control
Module), enabling the relays in this system to control the loads connected to it as well as
respond to a variety of inputs. These inputs include:
•Low Voltage (constant voltage)
•Photocell 0-10VDC or Switched
•Occupancy sensor
•0-10VDC analog
•Dry Contacts
The LCD display provides an easy user interface with full configuration from the front panel.
Cabinet Size # of Relays Weight Dimensions - in. (CM)

Feed and Load Wiring
The cabinets have been designed for multiple entry and exit points for feed (from branch
circuit breaker) and load wiring. Refer to the appropriate section in this guide which discusses
this topic.
Control Input Wiring
The cabinets have been designed for multiple entry and exit points for low voltage control
wiring. Refer to the appropriate section in this guide which discusses this topic.
Turn On
Prior to turn on, verify the following is installed correctly:

Mounting
The cabinets can be mounted only on the surface of the wall. The EZ-MAX Relay Cabinet is
not designed for any flush mounting method.
Prior to the consideration of any mounting location, please pay special attention to the allowed
locations for conduit entry.
All cabinets have ample location for conduit entry for feed, load
output, and control wiring. Ensure that conduit entry is only in
the allowed locations. Refer to the above figures in the
proceeding pages for possible locations. Also please ensure
that the power and control electronics are removed prior to
drilling or punching holes for conduit entry.
