The PEP provides a NATO slave cable connector that allows external generator power to be applied to the shelter.
The shelter grounding screw is located below the slave receptacle
The water-resistant cover (shown rolled) is held in place by magnets inside the outer seam of the cover.

Rev7).pptx (UNCLASS-FOUO) Export Controlled - See Slide 1
The battery compartment contains MTS power components:1. Two batteries that power the shelter when external power is not available. 2. The Outback power inverter. The Outback performs two functions :
A. Conditions incoming AC power to ensure a clean, uniform power sourceB. Converts input 24V DC power to 110V AC power when operating from
the MTS batteries or the vehicle’s alternator3. The Battery Charger Controller

Outback (Inverter):1. With vehicle running: converts 24V DC
power from the vehicle alternator to conditioned AC power for the MTS PCC, AC1 and AC2 circuits and the AC unit
2. With vehicle not running: converts 24V DC power from the MTS’ batteries to conditioned AC power for the MTS PCC, AC1 and AC2 circuits and the AC unit
3. With external AC generator power supplied: conditions input 110V AC power for the MTS PCC, AC1 and AC2 circuits and the AC unit

Battery Charger Controller:1. Automatically combines multiple
batteries (the MTS and vehicle power) when charging sources are available.
2. Automatically disconnects the vehicle battery from system loads when there is no active charging source. This ensures that the vehicle battery is not discharged.

The Power Distribution Unit (PDU) acts as a hub that distributes power to
equipment via the raceways inside the shelter.
The PDU provides circuit breakers that control
power to any circuit or combinations of circuits
