QUICK START
Turning On Your Volta System
To turn your system on, simply press the Volta Pushbutton. After a few seconds
of system checks, the ON/OFF button and Touchscreen lights up.
Turning Off Your Volta System
To turn your Volta system off, press and release the power button, then allow the
system a few seconds to power off. After it’s powered down, the touchscreen and
button will go dark.
Using the Touchscreen
Monitor the State-of-Charge (SOC) and control the Volta System via the touch-
screen.
The touchscreen turns on a few seconds after the pushbutton is pressed, a
charge source is sensed, or the vehicle is turned on.

Service and Contacting Volta Power Systems
Warning: Servicing instructions are for use by qualified personnel only.
To minimize the risk of electrical shock, do not perform any servicing
beyond what is specified in the operating instructions unless you are
qualified to do so. Any unauthorized attempt to service the system may
result in damage to the system, voiding of the warranty, and potential
injury.
Except for extended periods of storage, no specific maintenance is required for
the service life of the Flex Pack. In the event the Flex Pack has a breach of con-
tainer integrity or has been submitted to abusive operating conditions (crush,
short circuit, overcharge, over-discharge, submersion, evidence of combustion,
exposure to fire, etc.), please contact your authorized Volta representative.
Phone support is available during normal business hours. Visit the Volta Power
systems website for additional troubleshooting, Frequently Asked Questions,

These include but are not limited to the components
that comprise the Volta System, such as inverters,
chargers, and converters.
On/Off Pushbutton
or Volta Pushbut-
ton
Main system pushbutton that when pressed, turns on
the Volta System.
SOC State of Charge (SOC) indicates a percent of total pack
charge.
Touchscreen Main system display.

Manufacturer
Documentation
Supplemental documentation from the original
manufacturer of components included in the Volta
System.

120V or 120 VAC Synonymous with 110 VAC when referring to house-
hold appliances, devices, or outlets
System Maintenance
The Volta System and its components are maintenance free. However, depend-
ing on the integration of the Volta system, there may be components that are
recommended by the OEM or upfitter that may require regular maintenance.
For example, an OEM may recommend when to replace the belt on the second-
ary alternator. Refer to the OEM for recommended maintenance to ensure safe
operation.
Integrating Additional Components into the Volta System
Your Flex Pack is designed for connection and operation with Volta Power
Systems equipment or Volta Power Systems approved equipment. Using the
Flex Pack in other configurations may be unsafe and void the warranty. Opening
the Flex Pack housing also voids the warranty.
If you plan to integrate additional components not provided by Volta, like a 48V
air conditioning unit, contact Volta Power Systems and provide the component’s

documentation or specifications. This allows Volta to assess if the component
can safely integrate with the system. Volta may provide the appropriate interface
or connection for your existing Volta harness.
Volta’s assessment of these components are essential for the safe, reliable
operation of the Volta System as well as the personal safety of the individual
carrying out the work. It is the vehicle owner’s responsibility to make sure that
any equipment fitted complies with appropriate standards.
Any additional components of the Volta System shall:
•Ensure proper connections and circuit protection devices that meet
component requirements and the ANSI/RVIA LV standard for Low
Voltage Systems.
•Provide adequate support and strain relief for all connections.
•Confirm the component can be enabled/disabled by the Battery
Management System.
