housings or shipped as part of the ship kit. Ensure the O-Rings are in-place or installed before connection to the
controller. Ensure the O-Rings are not pinched or nicked during installation.
3.2 Grounding Requirements
The housings of the controller and motor must be wired together with large gauge copper wire (4 gauge or
larger, stranded or braided is recommended) to ensure proper electrical ground. There is a stud on the coolant
port side of the controller where the ground strap should be connected. The motor has a boss on the lead exit
end bell for the ground strap connection. The motor and/or controller are typically in contact with the metal
chassis of the vehicle, but this metal contact is not enough to provide the proper grounding path for the system.
WARNING
The user is responsible for providing and installing a ground strap from the motor to
the controller. Without a ground cable, erratic operation can occur.
3.3 Signal Cable
The signal cable (cable E in Figure 1.1 ) is the small shielded cable with a 17-pin Amphenol M23 style connector.
Some of the wires in this cable are used for the rotor position signals. Others are used to send stator and rotor
thermal information to the controller. Danfoss Power Solutions provides this cable as part of the
PowerPhase
® DT2 system, but the customer is responsible for connecting the signal cable from the motor to the
inverter. Connectors are keyed to require one orientation.
This is the most critical and sensitive cable within the drive system, and it must be protected from any potential
damage. It is also susceptible to loosening due to vibration if not properly torqued per instructions in
Section
3.3 . Erratic motor operation and even damage to the inverter may occur if this cable is allowed to loosen during
operation due to not being properly torqued.
WARNING
Do not attempt to lengthen or shorten the cable in any way. Contact Danfoss Power
Solutions if the cable is too short or too long for the application.
WARNING
Do not bundle the signal cable with the motor power leads. This may cause a
controller failure.
Signal cable connector assembly instructions
Note: These assembly instructions are only needed for the M23 screw type connector and not needed if your
system has the Bayonet type connector.
