Name	Location	Connector
DC +	Front left	Amphenol PL00X-301
Phase C	Centre left	Amphenol PL00X-301
Phase B	Centre	Amphenol PL00X-301
Phase A	Centre right	Amphenol PL00X-301
DC -	Front right	Amphenol PL00X-301
Low Voltage IO	Front left	Hirose F13WBRB-20SD
Automotive Ethernet	Front right	TE 9-2367359-1

The I/O ports are as follows:

All connectors on MC0-500 have an IP67 seal or better when mated with manufacturer-specified mating parts and properly sized wiring.

LV Connector

The LV connector on MC0-500 is the LF13WBRB-20SD from HIROSE. When mated, this connector achieves an IPX7/IPX8 rating. The mating part is either LF13WBP-20P or LF13WBLP-20P; both come in crimp and solder varieties and support shielding. The provided harness follows the diagram below, which also includes pinout information for the LV connector. Refer to the HIROSE documentation for additional information.

The pinout is as follows. The wire color and twisted pair group columns refer to the included shielded pigtail harness.

The LV input supports 11 V to 52 V operation on +LV_IN.

Ethernet Connector

The Ethernet connector on MC0-500 is 9-2367359-1 from TE. This connector and the associated hardware in MC0-500 are configured for 100BASE-T. When mated, this connector achieves IP6K9K sealing. At this time, the firmware interface is not implemented.

The recommended mating connector is 9-2367337, which is available in a variety of forms.

HV Connectors

Warning

If the correct OD wire is not used with the mated connector, the IP67 rating will not be achieved. Pay close attention to the required wire diameter when sourcing the harness.

MC0-500 has five high-voltage connectors, all of which are PL00X-301 connectors from Amphenol Industrial. Each has its HVIL (High Voltage Interlock) daisy-chained internally, and a fault is detected if any connector is improperly seated. To run MC0-500 at its maximum rated current, the mating part should be crimped with 70 mm² or larger wire. When mated, this connector achieves an IP67 seal.

The mating parts are PL18X-301, PL28X-301, PL10X-301, and PL20X-301.

Grounding

An M4x0.7x6 socket head cap screw is provided on the front of the enclosure, located above the low voltage connector.

Provide a continuous low impedance connection between MC0-500’s grounding point, chassis ground, and the motor’s ground.
