SAFETY PRECAUTIONS
CAUTION: High power electrical systems pose dangers independent of devices like the
Watt's Up and it is the user's responsibility to be familiar with these dangers and take any
necessary action to ensure safe use. Shorting a rechargeable battery or a
Watt's Up
connected to a rechargeable battery or battery charger can supply huge currents and have
serious consequences including explosions, causing fire, damage to equipment and
personal injury.
Please carefully read the entire SAFTY PRECAUTIONS section to ensure safe
product use.
3.1
Safe Operation Limitations
The Watt's Up is designed to be safe to use when operated within the parameter limits it
was designed for. Typical applications are well within these limits, but it is the user's
responsibility to be familiar with the Watt's Up specifications and ensure the unit is
operated within its limits.

CAUTION: Exceeding these limits may permanently damage the Watt's Up and may
cause personal injury and may cause fire.
3.2
Electrical Connections and Wiring
There are risks associated with the potentially high currents measured by the Watt's Up.
These include, but are not limited to, fire, burns and personal injury. The user must be
familiar with the relevant methods, procedures and connection components before using
or making any connection to the. It is suggested that any connectors and wires chosen for
use be appropriately sized and rated for the intended application and attached in the
manner recommended by their respective manufacturers.
CAUTION: Poor connections and reckless wire handling in electrical systems may have
serious consequences including personal injury, fire and property damage.
Intermittent and loose connections can cause component damage!
3.3
Powering Up
Verify there are no exposed wires or connectors at risk for a short circuit before
connecting a battery or power source to the Watt's Up.
The Red “SOURCE” and “LOAD” leads of the Watt's Up are connected to each other
and the Black leads are essentially so. This means the "other" side is electrically "hot"
when a battery or other power source is connected to either side.
CAUTION: Shorting a rechargeable battery or a
Watt's Up
connected to a rechargeable
battery or battery charger can supply huge currents and have serious consequences
including explosions, causing fire, damage to equipment and personal injury.
