1. SAFETY
1.1 General safety precautions
 All types of breakdown of the product may lead to a leakage of electrolyte or
flammable gas.
 During installation of the battery, the utility grid, solar input must be disconnected
from the Battery Pack wiring. Wiring must be carried out by qualified personnel.
Battery Pack is not user serviceable. High voltage or current is present in the device.
The electronics inside the Battery Pack are vulnerable to electrostatic discharge.
Observe the following precautions:
 Risks of explosion
 Do not subject the battery pack to strong impacts.
 Do not crush or puncture the battery pack.
 Do not dispose of the battery pack in a fire.
 Risks of fire
 Do not expose the battery pack to temperatures in excess of 122 ℉.
 Do not place the battery pack near a heat source such as a fireplace.
 Do not expose the battery pack to direct sunlight.
 Do not allow the battery connectors to touch conductive objects such as wires.
 Risks of electric shock
 Do not disassemble the battery pack
 Do not touch the battery pack with wet hands
 Do not expose the battery pack to moisture or liquids
 Keep the battery pack away from children and animals.
 Risks of damage to the battery pack
 Do not allow the battery pack to come into contact with liquids.
 Do not subject the battery pack to high pressures.
 Do not place any objects on top of the battery pack.
IMPORTANT NOTE: Circuit Breakers, Disconnects and Fuses should be employed throughout
several points of a power storage and generation installation to effectively isolate and protect
all components of the system to safeguard against faults, short circuits, polarity reversals or a failure of
any component in the overall system. Fuses, breakers, wiring ratings and values should be determined
by established standards and evaluated by certified electricians, licensed installers, and regional code
authorities. The Fortress Lithium Batteries must always be installed with a charge controller and the
appropriate settings to protect the batteries from open PV voltage and other high voltage charging
sources. The Fortress Battery Management System (BMS) alone will not protect the batteries from
these extreme electrical phenomena. Failure to adhere to installation protocol will void the Warranty.
CAUTION: Verify polarity at all connections with a standard volt meter before energizing the
system. Reverse polarity at the battery terminals will void the Warranty and destroy the batteries.
Do not short circuit the batteries.
