Warnings
• The port is protected to 30 VDC maximum. Exceeding this voltage may damage the port.
• Incorrect wiring may damage the versatile port or the connected device.
• All versatile ports in the unit have common ground, which connects to the grounds of other control ports.
That means versatile ports are not isolated from other control ports.
