2.2.1 Power Supply Connectors (J1, J2, J16)
The board is designed to operate in the DC voltage range of 12-48V. As shown in
Figure 2-2 , the Motor Control Board can be powered through either coaxial plug J1 or
through terminal connector J2.

( 1 , 2 )
If required, the power to the inverter can be disconnected by cutting the trace of the net
tie, NT1, and the rest of the circuitry can be powered through the supply connected to
the coaxial plug J1. The connection between the net tie can be bridged back by popu-
lating jumper J16, restoring the connection between J1 and J2, such that either input
connector, J1 or J2, can be used for powering the Motor Control Board. Connector J1
can carry current up to 2.5A and connector J2 can handle up to 24A.
Table 2-2 and
Table 2-3 summarize the pin assignments of connectors, J1 and J2, respectively.

Note 1: The Motor Control Board is designed to operate at a DC voltage range of 12V to 48V. When
powering the board through J1, limit the voltage to 24V Max. When the applied voltage is greater
than 24V, always use connector J2 to power the board.
2: When J1 and J2 are shorted through either J16 or NT1, always power the Motor Control Board
using only one connector, either J1 or J2.
