Please exercise care with the routing of this cables to prevent them from being scraped, damaged, cut, shorted,
unplugged, or disturbed by high voltage noise fields.
Do not
route these cables near any DC power cables or the
motor phase cables.
2.2.6
Routing the TCU to MCU Interface Cable
The TCU to MCU Interface Cable (cable C in
) provides 24 V power to the MCU, CAN signals from the
TCU, and RS232 com signals from the Diagnostic Software (
Section 8
). As with the Signal Cable, insuring data
integrity is required for optimum performance.
Please exercise care with the routing of this cables to prevent them from being scraped, damaged, cut, shorted,
unplugged, or disturbed by high voltage noise fields.
Do not
route this cable near any DC power cables or the
motor phase cables.
Note: When specifying a non-standard length for this cable, consideration must be given to the approximately
0.6 m distance from the face of the motor (the point of attachment for the Signal Cable) to the TCU mounting
bracket (the attachment point for the TCU to MCU Interface Cable).
2.2.7
Applying Voltage
For safe operation of the PowerPhase
®
DT2 system, the TCU must have the 24 V system powered up and the TCU
Enable (
Section 7.2.1.5
) and the MCU CAN Active (
Section 7.3.2.15
) signals must be set to true (1) before high
voltage is applied. The 24 V power must remain on and TCU Enable must remain true as long as high voltage is
applied.
If at any time either of these conditions is not met while the vehicle is in motion, the high voltage should be
disconnected from the inverter and the vehicle should be brought to a complete stop before high voltage is
reapplied to the inverter. Failure to do so may result in uncontrolled surges in high voltage which may damage
the high voltage battery, the high voltage battery control unit or the inverter itself.
CAUTION
For proper solenoid operation, the 24 V supply must be no lower than 20.4 V and no
higher than 28.8 V.

Installing the Motor & 2 Speed Transmission
The interface dimensions and tolerances of the PowerPhase
®
DT2 system can be found on the ICD drawing. Please
discuss any other methods with Danfoss Power Solutions Engineering before implementing.
2.3.1
Connection of the driveline to the transmission output flange
The output flange (mounts to transmission) is XS type, ISO 8667 cross serrated. The functional limiting torque of
the output flange is 14 kNm. The mating driveline flange mounts to output flange and is part of driveline
assembly. It is an XS type flange and shall comply with ISO 12667 requirements for cross serrated flanges. The
mounting fasteners used to join the output flange to the driveline flange will be supplied by customer and sized
according to driveline requirements. Driveline assembly must conform to a balance quality grade of G16 as per
ISO 1940-1-2003.
WARNING
Axial loading of the transmission output flange induced by the coupling system can
result in premature transmission failure. Users of the system MUST ensure the output
flange is not improperly loaded.
