System Components

Charger Enclosure

A waterproof sealed automotive–rated enclosure contains the EPJ charging components. The enclosure is located
under the truck or trailer typically near the lift gate (LG) batteries and is secured to the OEM stringers with aluminum
mounting channels. A power disconnect switch is located on the side of the enclosure to disconnect (LG) DC battery
power to the power inverter inside. Lifting and turning the latch opens the door to access the charging components
inside the enclosure.

Power Inverter

The Thermo King 2000 watt pure sine wave power inverter is mounted inside the enclosure. Cables are attached from
the inverter’s DC terminals to the power studs on the enclosure. Cables from the LG batteries are connected to these
power studs. The inverter changes the 12 volt direct current (DC) from the (LG) batteries into 2000 watts of continuous,
pure sine wave alternating current (AC), similar to the 120 VAC, 60 Hz voltage provided by your utility.

DC Power Cables

Cables from the LG batteries are connected to the DC power and ground studs located on the rear of the enclosure.
Inside the enclosure, cables from the studs are connected to the DC terminals on the inverter.

result and will void the warranty.
