Connecting the Hardware
To minimize risk of potential electrical shock hazard, be sure EVM is full deenergized.
Before connecting the boards, make sure the high current lug connectors (T1 and T2) are tightly secured
to the EVM PCB for low contact resistance. To minimize risk of potential electrical shock hazard,
deenergize EVM followed by use of a screw-driver, while clasping the nut on the PCB bottom side with a
crescent wrench.
NOTE:
It may be necessary to uninstall the nylon standoffs near the lug connectors before
manipulating the fasteners to avoid damaging them.
Connect the INA260EVM to the SM-USB-DIG board in the proper orientation, as shown in
. Make
sure that the two connectors are completely pushed together; loose connections can cause intermittent
operation.
