4.5.6 Motor sensor interface harness
A motor sensor interface harness is required between the MCU and the motor.
Note
: Carefully read all safety instructions related to electrical installation (Section 4.5.1) and general
information for installing cables and harnesses in Section 4.5.2 before continuing with your integration.
IMPORTANT NOTE
: Disable the high-voltage and auxiliary batteries before connecting or disconnecting
the motor sensor interface harness.
When the TM4 CO300HV-A MCU is to be used in a system with a motor from TM4, order a motor sensor
interface harness of a pre-determined length to be delivered with the system, contact Customer Service for
available lengths and part numbers.

Note
: Although it is not generally recommended to combine components of different versions; it is possible
to obtain specially designed adaptors from TM4 that allow you to combine a prototype motor with an Alpha
version MCU or a prototype MCU with an Alpha version motor. Contact TM4 Customer Service for more
information; see Section 5 for contact details.
4.5.6.1 Installing the motor sensor interface harness assembly
Before connecting or reconnecting the motor sensor interface harness connector, carry out a visual
inspection to ensure that the pins on both connectors of the harness are undamaged and that there is no
dirt or debris that might interfere with the contacts. Then, in order to protect the electrical contacts against
the surrounding environment, apply a contact lubricant (Electrolube CG60, NyoGel 760G or equivalent) to
the connector heads following the instructions provided by TM4 [9].
Note
: Although the signal connectors are fully watertight when correctly installed, we strongly recommend
that you help direct water away from the connector heads by creating a drip loop with the cable in your
installation.
Using the motor sensor harness delivered with your TM4 system, or the harness you have prepared for use
with a non-TM4 motor, connect the cable to the MCU using its dedicated mating location.
