Safety Warnings
This product generates high voltage that can cause
an electric discharge or electrocution resulting in
injury or death.
When installing the product, verify that:
•The traction battery (high-voltage battery) is
disconnected.
•The auxiliary battery (12V/24V battery) is
disconnected.
Care must be taken when manipulating electrical
equipment.
This product must be installed by qualified and
authorized personnel in accordance with applicable
vehicle standards and industry practices. Always use
appropriate insulation and protection before
manipulating the product even when the product is
disconnected from a high-voltage source.
Mishandling of this product may damage the
product and/or cause injury or death.
•All limitations and specifications
communicated by Dana TM4 regarding the
product must be respected.
•Do not attempt to open, repair or modify the
Motor Control Unit (MCU). In case of
damaged casing or suspected product
malfunction, contact Dana TM4 Customer
Service.
•Use only recommended points to lift and
secure the MCU.
•When using straps to lift the MCU, ensure
they do not touch or put pressure on any part
of the product exterior (surface, connectors,
and/or cables).
•Do not attach the motor to the MCU using a
shared support or bracket.
•Do not apply any external load to the casing
of the MCU.
The high-voltage cables MUST be shielded:
The external cables used for high voltage must be
orange and shielded; the high voltage and level of
current delivered by this product can be lethal.
Failure to shield the high-voltage cables will result in
non-compliance with EMI regulatory requirements.
This product uses differential mode capacitors
between the positive high-voltage DC bus (+) and the
negative high-voltage DC bus (-) and common mode
capacitors between the high-voltage DC bus and the
chassis.
Even when the product is disconnected from the
high-voltage source, these capacitors can hold a
voltage high enough to cause an electric discharge
or death.

Safety Warnings
Regardless of the cooling system used, when in a
system, the MCU can be irreparably damaged and
may become unstable if the coolant liquid pressure
reaches or exceeds a pressure of 30 PSI (static
pressure measured at the entrance of the MCU 
upstream of the MCU in the circuit).
Ensure that the pump is adjusted accordingly.
The cooling agent contains ethylene glycol that is a
highly flammable product. Ethylene glycol can burn
with an invisible flame that can cause serious burns
and/or other injuries.
Always handle the cooling agent carefully wearing
appropriate safety clothing and eye-glasses.
The cooling agent can irritate the skin, the eyes and
the mucous membranes.
•Always work in a well-ventilated area when
handling the cooling agent; breathing in high
concentrations of ethylene glycol can cause
nausea.
•In case of contact with eyes and skin, rinse
with water and consult a doctor.
•In case of ingestion, seek medical help
immediately.
The cooling agent is under pressure when heated;
removing the cap when the coolant is hot can cause
serious burns and/or other injuries.
Wait until the coolant reaches an ambient
temperature before removing the cap.
All potential dangers of handling cooling agents
cannot be listed here.
Consult manufacturer warnings and
recommendations for safe handling of the cooling
agent.
It is important to ensure that no voltage is present on
the high-voltage battery wires between both
polarities and from each polarity to chassis before
manipulation.
The vehicle integrator is responsible for ensuring that
proper training is given to all those who use this
system to avoid physical, electrical and operational
hazards.

General Information
Key Features
Dana TM4 Motor Control Unit (MCU)
The Motor Control Unit (MCU) system is operated via
CAN message communication between the MCU and
the Vehicle Management Unit (VMU) or Electronic
Control Unit (ECU).
The VMU or ECU is in charge of the user interface
and also interfaces with the Battery Management
System (BMS) and all other systems included in the
vehicle architecture.
The typical operation functions are:
•Applying power to the system from the
auxiliary battery.
•Asserting the enable signal to the MCU (VMU
/ECU or vehicle ignition).
•Performing high-voltage battery pre-charge
(VMU/ECU or BMS).
•Applying high-voltage battery voltage to the
system (BMS or BIM).
•Transmitting CAN messages (VMU/ECU)
with the MCU:
oStarting and stopping the system.
oApplying a mechanical torque.
oSafely shutting down the system.
oVerifying operational status.
Hazardous Voltage Interlock Loop (HVIL)
The Hazardous Voltage Interlock Loop (HVIL) internal
loop is closed, resulting in a short circuit between its
two input pins. The HVIL signal is used to open the
high-voltage battery contactor when its internal loop is
opened during product maintenance or repair (e.g.
removal of the MCU cover (MCU with removable side
cover) or disconnection of motor sensor cable)
thereby protecting the user.
Diagnostics Capability and Troubleshooting
Troubleshooting can be performed with the TM4
ODIN tool. It gives the list of events that occurred
during the operation and categorized the events such
as:
•Errors, which cause the product to cease
operation.
•Warnings and Information level events are
also recorded and must be taken into
consideration even though the product will
remain operational.

Safety Instructions
This product must be installed and manipulated by
qualified personnel who are fully aware of the types of
hazards involved in working with electrical circuitry
and are familiar with standard practices for preventing
accidents. The vehicle integrator is responsible for
ensuring that proper training is given to all those who
use this system in order to avoid physical, electrical
and operational hazards.
Safety warning related to operating the system
Mishandling of this product may damage the product
and/or cause injury or death.
•Do not attempt to open or repair this product.
In case of damaged casing or suspected
product malfunction, contact Dana TM4.
•Use only recommended points to lift and
secure the system.
When manipulating and/or installing this product, you
must NOT:
•Modify any part of the MCU.
•Apply any external load to the casing of the
MCU.
Applying excessive torque or speed when the motor
is cold may negatively impact the durability of the
system.
When the motor is used in an environment with an
ambient temperature of below 0°C, it is recommended
that you avoid using excessive speed or torque and
follow a normal driving cycle for the first few minutes
until the motor vehicle mechanical equipment has had
a chance to warm up.
Note: This is a best practice commonly applicable to
any mechanical equipment. The Dana TM4 motor
does not limit performance; full speed and torque are
available, but not recommended, after a cold start.
