Is voltage provided to the Distribution Box by an isolated ground
receptacle?
The distribution box must be powered by an isolated ground receptacle as per Gilbarco
installation requirements (these receptacles may be identified by their bright orange color and
triangular marking on the facing). This receptacle must be within 6 feet of the distribution box.
The distribution box must be powered directly by the AC receptacle through its Power Cable.
Extension Cables, surge protectors or UPS devices must not be installed in-line with the
distribution box. If an isolated ground receptacle is not in use, you will have to install one as
per Gilbarco requirements.

feed.
115 VAC Installations 103.5 – 126.5 VAC
230 VAC Installations 207 – 253 VAC
Note: Voltages exceeding this range may impact communication.
Are any other devices that are powered by the receptacle used by the
Distribution Box? If so, identify these devices.

In a Passport installation, the only additional acceptable equipment on this circuit is the
Passport Dispenser Hub and a dedicated UPS powering the Dispenser Hub only. Any
