2.1 Door Sensor
Inside the enclosure at the upper right is a door sensor to indicate when the door is open or closed. If the door is open for
more than 60 seconds, a fault is indicated and the enclosure is disconnected from the DC bus.
2.2 Power Chassis Assembly
The power chassis assembly (PCA) is a 4U enclosed section that controls the connection of the battery enclosure to the
DC bus. The PCA monitors each battery module's voltage and temperature to ensure operation within the manufacturer's
specified limits throughout the life of the product.
IMPORTANT! Operation of the Vertiv™ HPL Lithium-Ion Energy Storage System outside its recommended
environmental or power limits may void the warranty.
