General
This control panel utilizes a mixture of traditional controls along with a “smart” digital circuit board
controller, referred to as the ECPM03 control board. It is intended to be installed within a UL508A
electrical control package. The board is powered by 24 Volts DC, which is provided by an approved 10-20
Watt class 2 power supply included inside the panel.
Some parts of the ECPM03 circuit board can be electrically live and some surfaces can be hot.
Inappropriate use and incorrect installation or operation creates the risk of injury to personnel and/or
damage to equipment. All operations concerning installation, commissioning and maintenance must be
carried out by qualified, skilled person who is familiar with the installation, assembly, commissioning, and
operation of the control panel and the application for which it is being used.
Installation
Ensure proper handling and avoid excessive mechanical stress. Do not bend any components during
transport, handling, installation or maintenance. Do not touch any electronic components or contacts. This
board contains electrostatically sensitive components, which can easily be damaged by inappropriate
handling. Static control precautions must be adhered to during installation, testing, servicing and repairing
of this board. Component damage may result if proper procedures are not followed.
To ensure proper operation, do not install the board where it is subjected to adverse environmental
conditions such as combustible, oily, or hazardous vapors; corrosive chemicals; excessive dust, moisture
or vibration; direct sunlight or extreme temperatures.
The ECPM03 may be mounted by means of DIN rail clips and board standoffs or by standoffs alone. It
will be mounted in a NEMA 1 enclosure for indoor use only.
When working on live panel controllers, applicable national safety regulations must be observed. The
electrical installation must be carried out according to the appropriate regulations (e.g. cable crosssections, circuit breaker, protective earth [PE] connection). While this document does make
recommendations in regards to these items, national and local codes must be adhered to.

WARNING: DO NOT LIFT CONTROL BY WIRING COMPONENTS
Site Preparation
1. Provide clearance around installation site to safely install equipment into its final position.
Supports must adequately support equipment. Refer to manufacturer’s estimated weights.
2. Consider general service and installation space when locating unit.
Assembly
When the control panel is ordered in a utility cabinet installed on the hood, there is no mechanical
assembly required by the installer. If the control panel is ordered as a wall mounted panel, the enclosure
must be secured to a fixed wall near the exhaust hoods. Be certain to maintain adequate clearance
from excessive heat sources such as appliances to prevent damage of the components.
Utility Cabinet Installation (Typical)
Room Sensor Installation
A room temperature sensor is provided with the panel. It should be installed in a safe location, free of
influence from external heat sources. It should be indicative of the average kitchen temperature away
from the appliances. For packages with 2 separate fan zones, a 2nd room sensor may require installation.
Refer to the Installation Schematic for landing terminal locations.

Wall Mount Installation (Optional)
Mount control panel with adequate
clearance from excessive heat
sources such as appliances to prevent
damage of the components.
IMPORTANT!!
When exhaust duct connections are located and cut in the field, duct temperature probes are
shipped loose in the electrical package enclosure. These must be installed in the duct
immediately above the hood for proper system operation.
Duct Sensor Installation
When the control panel is ordered, the system typically consists of one duct sensor per hood exhaust
riser. These sensors are typically shipped factory installed in factory assembled hood risers. If the risers
are field cut, the sensor and other components are shipped loose for field installation as shown below. A
hole must be cut in the grease duct, and the quick seal and sensor must be assembled as shown below.
A 2-wire plenum rated thermistor cable (18 gauge typical), run in conduit, should be used to wire the
sensors back to the controller and landed on connector J10 as indicated on the installation schematic.

WARNING!!
Disconnect power before
installing or servicing control.
High voltage electrical input is
needed for this equipment. This
work should be performed by a
qualified electrician.
Before connecting power to the control, read and understand
this entire document. As-built wiring diagrams are furnished
with each control by the factory and are attached either to the
door of the unit or provided within a paperwork pouch internal
to the panel.
Electrical wiring and connections should be done in
accordance with local ordinances and the National Electric
Code, ANSI/NFPA70. Be sure the voltage and phase of the
power supply and the wire amperage capacity is in accordance
with the unit nameplate.
1. Always disconnect power before working on or near
this equipment. Lock and tag the disconnect switch or
breaker to prevent accidental power up.
2. Make certain that the power source is compatible with
the requirements of your equipment. The installation
wiring schematic identifies the proper phase and
voltage of the source breakers.
3. Before connecting control to power source, verify
power line wiring is de-energized.
4. Secure all wiring to prevent contact with sharp objects.
5. Do not kink power cable and never allow the cable to come in contact with oil, grease, hot
surfaces or chemicals.
6. Before powering up the system, make sure that the interior of the control is free of loose debris,
metal shavings, or shipping materials. `
7. If any of the original wire supplied with the system must be replaced, it must be replaced with type
THHN wire or equivalent.
High Voltage Wiring
1. All high voltage wiring shall be terminated on the right side of the
terminal blocks or directly on the starters as designated in the
circled areas on the left hand diagram.
2. There are multiple electrical connections required for this
control. 120VAC should be wired to terminals H1 and N1. Input
power to the motors should be wired to “L” series terminals. Motor
output power should be connected to “T” terminals on the starters.
3. The hood light wiring will also need to be wired to terminals as
indicated on the installation diagram.
4. If an ANSUL fire system is present, the fire system micro-switch will
need to be wired to terminals as indicated on the installation
diagram, typically “C1”, “AR1”. C1 is the common and connects to
terminal 1 on the micro-switch. AR1 is the armed state and
connects to terminal 2 on the micro-switch. If a CORE fire system is
present, this connection is not required.

Low Voltage Wiring
Low voltage field wiring consists of Duct and Room Temperature sensors, ECM motors, 0-10VDC output,
24VDC input, or Modbus communication over CAT-5 cables for HMIs and remote equipment.
Additionally, panels can be ordered with Building Management Options. Refer to the Building
Management Owner’s Manual, if equipped, for low voltage building management wiring requirements.
Low voltage wiring must be run through the wireway show below in the grey rectangle area. Wires will be
terminated on the terminals located on the ECPM03 board, circled below.
WARNING: Low voltage wires should never be run together with high voltage wires.
1- Room temperature sensor(s): For all installations utilizing duct
thermostats, at least 1 room temperature sensor must be installed in a
safe location, free of influence from external heat sources. It should be
indicative of the average kitchen temperature away from the appliances.
For packages with 2 separate fan zones, 1 or 2 room sensors can be
used. 2-wire 18 AWG thermistor cable must be used. The room
temperature sensor shall be wired according to the installation wiring
schematic, typically terminals “T1A”,”T1B”.
2- Duct temperature sensors: For all installations excluding a single
hood with factory risers and a hood mounted panel, duct mounted
temperature sensors will need to be wired in the field. 2-wire 18 AWG
plenum rated thermistor cable must be used. The temperature sensor
should be wired to terminal blocks as indicated on the installation wiring
schematic.
3- HMI(s) are connected to the ECPM03 board through CAT-5 cable. The HMI have two RJ-45
connectors connected together for Modbus.
a. If the panel was ordered with only 1 fan switch and/or 1 light switch, the HMI would connect
to port J4 (RJ-45) of the ECPM03 board. The other RJ-45 port of the HMI will typically be
occupied by a RJ-45 end-of-line terminator (Part # EOL120A).
b. If the panel was ordered and configured for 2 fan or 2 light switches, the first HMI would
connect to port J4 (RJ-45) of the ECPM03 board. The second HMI would connect to
ECPM03 board two ways:
o Connect the second HMI to the first HMI through CAT-5 cable. In this case the RJ-45
end-of-line terminator (Part # EOL120A) would only be used on the second HMI.
o Connect the second HMI to port J5 (RJ-45) of the ECPM03 Board. The other RJ-45
port of the HMI will typically be occupied by a RJ-45 end-of-line terminator (Part #
EOL120A).
4- Two end-of-line terminators (Part # EOL120A) are included in each panel. They are typically
plugged in at the factory on J3 and either on port J4 or in the back of the first HMI. If another HMI or
other equipment need to connect to a port occupied by an end-of-line terminator, it shall be removed
and place on the HMI or equipment that became connected at the end of the Modbus network.
NOTE: A third end-of-line terminator would be included with the package if the panel is ordered with 2
fan or 2 light switches. The extra end-of-line terminators will be mounted on the second HMI, if
decided to connect the HMI to J5. Otherwise, if daisy chained both HMIs, the third-end-line terminator
should be mounted on J5.
5- If other pieces of equipment such as PCU Advanced Filter Monitoring (AFM) are connected to this
panel, a cat-5 cable will also be used to run the Modbus communication between these devices. The
cable would be plugged in port J3 of the ECPM03 board. The end-of-line terminators should then be
relocated from J3 to the empty RJ45 port of the PCU AFM module.
