GND (Note: Zaber's power supplies ground this pin to AC Earth)

Note: To prevent damage to the device due to static buildup, the device should be properly
grounded. The power supplies Zaber provides for X-Series devices are non-isolated and thus
ground the device chassis to Earth via the negative terminal of the power supply.  If for any reason
you are using an isolated power supply, please ensure your device is grounded by connecting the
negative terminal of the power connector to AC Earth.
