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.
