DESCRIPTION
The CX Panel is shipped in one package. Panels are congured with all 16 or 24 relays of the same type installed or with space
only for relays to be installed in the eld. The relays are mounted with lighting circuit terminals in the high voltage area. The
low voltage control inputs are located in the low voltage area of the panel.The following information describes the CX 16 and
24 relay panel installation. For programming information, refer to the “CX Panel Quick Start Guide” provided as a separate
document with the Panel.

Example: CX162S162NM - CX 16 Relay Panel, 120-277VAC universal input, with 16 20A/1P N/O Electrically Held Relays
installed in NEMA 1 Surface Mount Master Panel.
Panels are available fully populated with a single relay type or with SP option (Space Only) to allow for eld installation of
individual relays.This is the methodology to provide for panels with a mix of more than one type of relay. Relays can be ordered
separately as follows:

ENCLOSURE MOUNTING
Typically the CX panel is installed near the circuit breaker panel or in the ceiling of the room containing the lighting circuits
to be controlled. Select an appropriate location that meets the environmental conditions listed in the specication section of
this document.The panel interior is divided into high voltage and low voltage areas as shown in Figure 1 on page 3. Select an
appropriate location for incoming line voltage panel power, branch circuits to be controlled and low voltage input wiring.The
housing is supplied with conduit knock-outs labeled to indicate line or low voltage wiring use.All terminations within the panel
enclosure require installation by a licensed electrician in accordance with National and/or local Electrical Codes.

FIGURE 2 - ENCLOSURE MOUNTING HOLES
Locate the enclosure on the mounting surface and use a level to ensure that it is properly oriented and aligned. Secure the
enclosure to the mounting surface with hardware as appropriate for the application using the three keyed mounting holes
located near the top corners and in the center bottom of the enclosure as shown below in Figure 2.

INSTALLING INDIVIDUAL RELAY CARDS
Relay Panels are most commonly shipped with all relay cards installed. If the project requires different types of relays installed
in the same panel then the relays are supplied separately and they will require eld installation. In this application reference the
applicable Relay Installation Instructions supplied with the individual Relay Cards on how to install relays.
Caution: ALWAYS remove supply power to the Panel control Transformer prior to making any connections between relay
boards and panel processor board. Failure to do so may result in personnel injury, damage to the panel, and void its warranty
CONNECTING PANEL POWER
The panel is designed to operate on 120, 208, 240, or 277VAC for input voltage “2” designator or 347VAC for input voltage
“3” designator. Panel input power is supplied to the power supply located in the upper center of the panel as shown in Figure
1 on page 3.With the power turned off, route the dedicated panel power supply leads to the transformer and connect them
to the appropriate system voltage specic leads. Connect the power supply ground lead to the panel chassis grounding lug. A
label indicating this ground lug is located adjacent to the connection location.
Caution: When power is applied to the transformer, the unused transformer leads become electried. Cap unused
transformer leads with wire nuts to prevent electrical shorting.
CONNECTING LIGHTING LOADS
With the power turned off, route the lighting system line and load leads through the high voltage area of the panel shown
in Figure 1 on page 3. Connect line and load leads for each lighting load to the output terminals of the appropriate relay as
delineated in the project plans and/or Panel Load Schedule.
Notice: As a general rule, the panel is shipped with relays installed and electrically connected at their input control side. If,
however, relays must be installed, reference the applicable Relay Installation Instructions supplied with the individual Relay
Cards on how to install relays.
Caution: Prior to making any connections to the relay outputs, verify that none of the loads are shorted. Failure to do so may
result in personnel injury, damage to the panel, and void its warranty
Notice: If no Panel Load Schedule exists, use the Panel Load Schedule Form supplied in the clear plastic pocket inside the
Panel Door to record the lighting circuit relay assignments while connecting the relays
CONNECTING LOW VOLTAGE INPUTS
Bring the low voltage wiring for the contact inputs in through the knockouts in the low voltage wiring area where indicated
in Figure 1 on page 3.The CX 4 Relay Panel supports six inputs and the CX 8 Relay Panel supports 12 inputs. Inputs are
software congurable through programming to support momentary switches, maintained switches (latching), motion sensors,
or photocells. Each Relay Card includes one low voltage input.The panel mother board includes 2 Auxiliary Inputs for the CX
4 Relay Panel and 4 Auxiliary Inputs for the CX 8 Relay Panel.These inputs may be connected prior to programming. Inputs
may be connected to any terminal location regardless of nal control programming. Connect contact closure input devices to
the input terminals using 18 AWG wire.
Notice: Use the Panel Load Schedule Form supplied in the clear plastic pocket inside the Panel Door to record the low voltage
input types while making connections.

OPERATING THE PANEL
The User Interface control ribbon cable is supplied connected between the User Interface Ribbon Cable Connector on the
Mother Board and the User Interface Module that is attached to the panel door.The red indicator in the cable should align
with the Pin 1designation. The green ground jumper is supplied connected between the panel door and the panel housing
ground lug, labeled “GND”. Provide control power to the panel and restore power to the lighting circuits at the source circuit
breakers. The panel will take a few moments to initialize during which time the User Interface screen on the front of the
panel door will initiate and display the clock, date, and time zone un-programmed factory defaults. Inside the panel the Mother
board power status LED will show continuous “green”.The Relay board status LED will turn on “green” for approximately 2
seconds and then go off. Push, but do not hold the Relay Manual Control button on each relay card to operate each relay to
test functionality.The Relay State Status LED will turn on “red” when the relay is energized and be off when the relay is un-
energized.The panel is now fully functional and ready to control the lighting loads.
