Personal Safety Precautions; Before Using Your Converter - Schumacher Electric XI41B Guide D'utilisation

2. PERSONAL SAFETY PRECAUTIONS

2.1 Restrictions on Use: This converter may not be used with life support devices or
systems. Failure of this converter can reasonably be expected to cause failure of that life
support device or system, or to affect the safety or effectiveness of that device or system.
2.2 Wear complete eye and clothing protection when working near lead-acid batteries.
Always have someone nearby for help.
2.3 Remove all personal metal items from your body, such as rings, bracelets,
necklaces and watches. A lead-acid battery can produce a short circuit current
high enough to weld a ring to metal, causing a severe burn.
2.4 Never smoke or allow a spark or flame in the vicinity of the battery or engine.
2.5 WARNING: This product contains one or more chemicals known to the State of
California to cause cancer and birth defects or other reproductive harm.

3. BEFORE USING YOUR CONVERTER

• This converter is designed to be used with a single battery, up to group 31 (130
Ah or smaller). The recommended source of power is a 12 volt deep-cycle battery,
due to their high reserve capacity. Automotive batteries are recommended for only
a short period of time of an hour or less.
• Do not use the converter with a product that draws a higher wattage than the
converter can provide, as this may cause damage to the converter and product.
When you turn on a device or a tool that runs on a motor, the device goes through 2 stages:
1. Start Up – Requiring an initial surge of power (commonly known as the
"starting" or "peak" load).
2. Continuous Operation – Power consumption drops (commonly known as the
"continuous load").
The wattage (WATTS) or amperes (AMPS) can normally be found stamped or
printed on most devices and equipment, or in the user's manual. Otherwise, contact
the manufacturer to find out whether the device you want to use is compatible with a
modified sine wave.
To calculate the wattage: Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load: Starting Load = 2 x wattage.
In general, the startup load of the device or power tool determines whether your
converter has the capability to power it.
Always run a test to establish whether the converter will operate a particular piece of
equipment or device. In the event of a power overload, the converter is designed to
automatically shut down.
This safety feature prevents damaging the converter while testing devices and
equipment within the wattage range of the converter.
