1.0 Warnings and Precautions
The following symbols indicate important safety warnings and precautions throughout this guide:
WARNING indicates that serious bodily harm or death may result from failure to adhere to the
precautions.
CAUTION indicates that damage to equipment may result if the instructions are not followed.
NOTE suggests optimal conditions and provides additional information.
1.1 Warranty Disclaimer
This guide will familiarize you with the features and installation of Carmanah's unified Energy Management
System (EMS). Failure to comply with the use, storage, maintenance, installation or placement instructions
detailed in this guide could void the warranty.
1.2 Standards
Perform all installation, wiring, grounding and maintenance in conformance with local building and electrical
codes. Adherence to the National Electrical Code (NEC) is mandatory to comply with any certification markings.
Non-adherence to code may void the warranty.
1.3 Safety and Usage Precautions
Use extreme caution when handling the batteries as they can generate hazardous short-circuit
currents. Remove all jewelry (bracelets, metal-strap watches, etc.) before handling the batteries.
Solar panels produce DC electricity when exposed to light and can therefore produce an
electrical shock or burn. To render solar panels inoperative, remove them from sunlight or fully
cover their front surface with an opaque material.
Before lifting any heavy or bulky equipment, ensure the load is secured so moving parts do not
shift, and that it can be lifted as far as needed without back strain or loss of grip. Installation may
require more than one person.

REPLACEMENT GUIDE
Ensure the equipment is not powered during installation and wiring of the system.
Recheck all completed wiring for proper polarity prior to energizing the system.
Changes or modifications to Carmanah equipment not expressly approved by Carmanah could
void both the user's authority to operate the equipment and the warranty.
All Carmanah traffic products use a constant-current LED output circuit. Not all traffic beacons
are compatible with this output. Please contact Carmanah for additional information and guidance
when adding or replacing beacons or other hardware.

2.0 Energy Management System (EMS) Overview
Relay Control/Monitoring:
EXT1 (also labelled as OUT1 on G Series wiring terminal block) – Used for Applied Information time switches
only. Pulses of voltage (relative to DC-) indicate the system is operating with no detected fault. This “heartbeat” is
used as part of Carmanah’s StreetHub system monitoring through the Applied Information time switch.
EXT2 (also labelled as OUT2 on G Series wiring terminal block) – This terminal provides a steady +12 V
(nominal, relative to DC-) signal whenever the fixtures are activated and no faults are detected. This digital output
is commonly used for triggering a relay to power third party devices or overhead lighting while a fixture is active. It
is also used for certain push button applications.

3.0 Installation Procedure
This guide is for installing a replacement unified Energy Management System (EMS) into one of the following
compatible Carmanah systems:
•Legacy – R920, R247-E, SC315
•E Series – R920-E, R820-E, R247-E, R829-E
•F Series – R920-F, R820-F, R247-F, R829-F
•G Series – SC315-G, R820-G, R247-G, R829-G
Refer to the individual product user manual for more details at support.carmanah.com. Depending on your system
configuration some connections may not be used. The unified EMS is used in all models listed above and
contains the same firmware across the board. There’s an optional radio and calendar add-on depending on your
application. There are also several user adjustable settings that will change the way the system will function. Do
not adjust the factory settings unless specified by Carmanah.
The images in this guide may differ from your system. They are for illustrative purposes only.
Legacy R920/R247-E systems will receive a new EMS preassembled to a new enclosure. Refer
to Section 3.2 for filling out the new label.
3.1 Removing Existing Energy Management System
1. Remove power to the system. For AC-powered systems, turn off the circuit breaker in the cabinet and for
solar-powered systems remove all fuses (battery and if applicable solar). For solar-powered systems, it
may be beneficial to remove the battery or batteries for easier access to the EMS. Ensure the battery
terminals do not get shorted during this process.
2. Remove the four screws/washers securing the EMS enclosure and set aside. The image below is for an E
Series engine, the F Series engine looks very similar but will be larger. The process is the same for an F
Series engine.

a. For legacy SC315 cabinets, you will need to remove the four security screws on the rear of the
cabinet. This requires a 5/32” hex security bit. Be careful not to strip the screws. Use forward
pressure on the rear of the cabinet and from the inside press against the EMS mounting bracket
when loosening the screws.
b. Current G Series cabinets will have four mounting screws on the right-hand side to remove.

c. Some G Series cabinets may have a dual EMS configuration so there will be one on each side of
the cabinet. Simply remove the two inner screws and then loosen the two outer screws.
3. If the optional radio is present, carefully remove the radio module from the EMS and then remove the
antenna connector with a 5/16” wrench. Older systems will have radio module cable tied in place which
makes it easier to remove the antenna connector without removing the module.

4. Review the existing wiring and take an image as needed for future reference. The wiring layout for this
control board is provided in Section 2.
5. Remove all wiring on the control board by lightly pushing down on wire release button with a small flat
head screwdriver and pull back on the wires. Remove the solar panel wires last and cap off temporarily
with wire nuts or insulation tape. If required, you can cover the solar panel while working on the system
for added protection.
6. Remove the four mounting screws that are securing the EMS to the enclosure and set the EMS aside.
Older systems will have five mounting screws to remove.

3.2 Installing Replacement Energy Management System
1. Remove the new EMS from its antistatic bag and secure it to the enclosure with the four previously
removed screws. Sensitive electronics can be damaged by electrostatic discharge (ESD). Observe proper
ESD precautions when installing the new EMS.
a. You will receive either a bare EMS or one preassembled to a new enclosure. The new enclosure
is for older legacy R920/R247-E systems that originally used a smaller EMS and enclosure
footprint.
b. For replacement controllers that come preassembled to the enclosure you can discard the
existing enclosure. Copy over the existing system settings and system serial number (10 digits)
onto the new label on the front of the enclosure. This will help retain the original system serial
number for future tracking purposes.
2. Beginning with the solar panel wires, check that the wire strands are straight and that all the strands will
go into the terminal. This will avoid short circuits.
3. Reconnect all wires with the correct polarity as shown in Section 2. The wire can be pushed directly into
the terminal but you may use a small flat head screwdriver to push to down on the wire release button
while inserting the wire as needed. Ensure wires are fully inserted. Carefully pull on the wires to ensure
they are secure.
4. If the optional radio is present carefully connect the antenna to the new EMS. Push down on the radio
module while tightening the antenna connector and ensure it is snug.

5. Replace any cable ties that were removed to ensure wires have proper strain relief.
6. Secure the EMS enclosure back into the solar engine or cabinet with the four screws/washers removed
from Section 3.1.
7. For solar-powered systems, reinstall batteries as required and reconnect all fuses removed from Section
3.1. For AC-powered systems reinstall any fuses that were removed and turn on the breaker.
8. The EMS should now power up and is ready for operation. Normally, the EMS is preconfigured by
Carmanah for your specific installation, but the settings can be changed at any time. For crosswalk
applications you may need to adjust the crossing duration and radio channel to match the current
configuration for your application. Please refer to the specific product manual at support.carmanah.com
for more information or contact Carmanah for assistance.
