Note:
Install the wire jumpers between terminals SC-SP and SC-SN to set the MFDI power supply.
• SINK Mode: Install a jumper between terminals SC and SP.
Do not short circuit terminals SC and SN. Failure to obey will cause damage to the drive.
• SOURCE Mode: Install a jumper between terminals SC and SN.
Do not short circuit terminals SC and SP. Failure to obey will cause damage to the drive.
• External power supply: No jumper necessary between terminals SC-SN and terminals SC-SP.
