How It Works

System Components 

The SAFEX uses a system of components to safely provide 480 VAC power for your eTRU. Each component is outlined on the system diagram and includes the 1. Auto Eject, 2. Auto Safe, and 3. Your choice of cable management.

The SAFEX system is customizable and allows you to choose the cable management component that works best for your fleet.

1. The Auto Eject

The Auto Eject is installed on the trailer. It includes a 480 volt, 30 amp receptacle that automatically detects when the cable has been connected and ensures that the cable is not live unless properly connected. When the driver pushes and releases the tractor brake, the Auto Eject does its job by ejecting the cable to the ground (ready for your choice of cable management to take over) and disconnecting power so that the cable is no longer live.

2. The Auto Safe

The Auto Safe can be installed on the warehouse or on a designated shore power station out in the lot. When the Auto Safe receives the signal from the Auto Eject that the power cable is properly connected to the vehicle, it allows the operator to activate the power with the simple push of a button. When the Auto Eject disconnects the cable, the Auto Safe automatically deactivates the 480 volt power cable to prevent accidental electric shock to personnel.

3. Cable Management

The basic SAFEX package includes a sturdy cable hanger that the cable can be coiled on after the vehicle drives away. More convenient and robust cable management systems are available in the form of the:
  • Manual Reel – allows an operator to tug the cable to activate the spring-loaded reel, which then neatly coils the cable
  • Auto Reel – automatically coils the cable once it detects that power has been shut off, allowing for quick cable cleanup without requiring the operator to interact with the system
  • Auto Reach – automatically retracts the hanging cable to the warehouse or shore power station

Any of these options allow the cable to be removed from the ground, ensuring that tripping hazards and other potential cable-related risks are mitigated.
