Primary Disconnects

Ethernet Disconnects

By connecting to the site’s emergency stop system, Ethernet Primary Dispenser Disconnects provide low voltage disconnection for dispensers that use Ethernet network cabling for primary dispenser communication. Models are available that will disconnect 1 or 2 Ethernet cables for 8 dispensers or disconnect one Ethernet cable for 16 dispensers.

PRIMARY DISCONNECTS

Primary Disconnects provide emergency stop and service disconnect switches for dispenser data and credit card data circuits.


Emergency Stop

In the event of an emergency stop, the Primary Dispenser Disconnect will disconnect the dispenser data and credit card communication circuit.

Safe Maintenance

Toggle switches, located behind a lockable cover, allow maintenance personnel to isolate the conductors of a single dispenser for servicing purposes.

NFPA® and NEC® Code Compliance

Dispenser Disconnects provide compliance with NFPA® and NEC® Code requiring emergency disconnect and maintenance disconnects at all motor fuel dispensing facilities.

ETHERNET PRIMARY DISPENSER DISCONNECTS

Primary disconnect for dispenser data and credit card data for dispensers equipped with Ethernet circuits for data communication.

Emergency Stop Connection

Connect to the emergency stop system by the means of a Class 2 transformer that is plugged into an outlet controlled by the emergency stop system.

Expandable

Expandable to allow disconnecting of additional secondary communication circuits such as intercom and media circuits. This is easily done by connecting the secondary disconnects to the remote expansion port located on the side of the primary disconnect.

Individual Disconnects

Individual disconnects for each circuit types allows the disconnect to be located where the conductors enter the building. This can eliminate costly additional wiring and downtime that maybe required to re-route conductors to a central location such as the electrical room, during a retrofit or site upgrade.
