450H inverter polarity

Hi. Quick question on the inverter.
Is the HV polarity the same orientation between RHD and LHD inverters, ie, positive always on the left, negative on the right?
This pic from the wiki looks like the RHD unit

Mines from a LHD, has the HV connectors on the opposite side of the inverter. Are the + / - the same?

MANY THANKS

Polarity is the same as above on LHD models. You can also test this using a multimeter in diode mode between the HV bus and one of the motor phase output terminals
