Overview
Introduction
The Z-MAX Remote Relay Panels, also referred to as Z-MAX Slave
Relay Cabinets, are designed for remote installation and
mounting where relay switching from 4 to 48 load circuits is
desired, but control intelligence, programming, and interface to
other systems is required at a central location. This system of
remote relay panels has the following benefits over the traditional
configurations:
•Remote mounting of relays where control electronics are
inconvenient
•Single point of programming when a continuous extension of
an existing relay panel is desired
•Other unique applications where configuring at the relay itself
is not desired
Installation Overview
Installing a remote relay cabinets involves only a few steps:
Step 1: Mounting the relay cabinet to the wall, install
conduit, and pull all wire.
Step 2: Terminate line voltage wiring
Step 3: Terminate any low voltage wiring
Step 4: Terminate the Master/Slave networking wiring
Step 5: Inspect your work
Step 6: Power-up, configure, and test the system
Each of the above steps are covered in detail throughout the rest
of this user’s guide. In each section notes, warnings,
requirements, suggestions, and procedures are included which
will help you be successful in the installation and use of your
system.

Inspection
Carefully unpack the relay cabinet, and inspect to make sure
there is no hidden shipping damage. Report any damage to the
freight carrier who delivered the system. Claims for damages are
filed with the freight carrier.
In case of damaged components, your relay cabinet may be
serviced in the field with factory replacement parts.
Physical Description
Remote relay panels are classified by the number of load circuits
they can switch. The fewer the number of controlled circuits, the
smaller the overall cabinet dimensions, and the larger the
number of controlled circuits, the larger the overall cabinet
dimensions. The physical properties of the cabinets are as
follows:

•Quick & Easy to Configure
The control portion of the relay cabinet employs all digital
circuitry for accuracy and minimum wiring requirements between
the relay cabinet and its control systems.
Control Overview
The Leviton Z-MAX remote relay cabinets use an intelligent
central control card (Digital Main Control Module) and a
dedicated system of networking wiring, allowing for control of the
relays in the remote cabinet from any control source connected
to the master relay cabinet and from any low voltage source
connected to the remote relay cabinet.
Control input to a remote relay cabinet can be any combination of
the following:
•Low Voltage momentary or maintained
•Momentary 2-Pole On/Off
•Photocell 0-10VDC or Switched
•Occupancy sensor
•0-10VDC analog
•Dry Contacts
Following the basic premise of remote relay cabinet, even though
each remote relay cabinet can accept control inputs, these inputs
are processed by the master control panel for configuration and
relay control.
Remote relay cabinets require a dedicated physical network of
certified category-5 wiring utilizing RJ-45 connectors at each end.
The panels should be laid out in a linear "daisy-chained" fashion.
In the event that this network topology is not convenient, hubs
and/or routers may be available to facilitate this topology.
Contact the factory for additional information.

Conduit Entry Locations
The cabinets have been designed with specific locations
supporting conduit entry for line and low voltage circuits. There
are specific areas of the cabinet which are restricted from some
or all types of conduit access. Reference the Physical Installation
section of this manual for specific details.
Line & Load Circuit Wiring
Each relay requires line & load circuit wiring. The line wiring
should come from an over-current device and the load circuit
wiring shall go to the specific load to be controlled. On some
models which have integrated branch circuit protection, the line
side of the relay has been pre-wired to a circuit breaker. With
these products, only the load side of the circuits needs to be
connected.
Turn On
Prior to turn on, verify the following is installed correctly:
•Feed wiring
•Load wiring
•Control wiring
