1.2 Precautions When Working with Batteries
1-2-1. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye,
immediately flood eye with running cold water and seek medical attention immediately.
1-2-2. Never smoke or allow a spark or flame in the vicinity of a battery or engine.
1-2-3. Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery may cause
an explosion.
1-2-4. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
lead-acid battery. A lead-acid battery produces a short-circuit current high enough to weld a ring or the like
to metal, causing a severe burn.
1-2-5. To reduce the risk of injury, charge only deep-cycle lead acid, lead antimony, lead calcium gel cell,
absorbed mat, or NiCad/NiFe type rechargeable batteries. Other types of batteries may burst, causing
personal injury and damage.
2. Introduction
2.1 General Information
The Global LF Series Pure Sine Wave Inverter is a combination of an inverter, battery charger and AC
auto-transfer switch into one complete system with a peak conversion efficiency of 88%.
It is packed with unique features and is one of the most advanced inverter/chargers on the market today.
It features power factor corrected, sophisticated multi-stage charging and pure sine wave output with
unprecedentedly high surge capability to meet demanding power needs of inductive loads without damaging
the equipment.
For the regular model, when utility AC power cuts off (or falls out of acceptable range), the transfer relay is
de-energized and the load is automatically transferred to the Inverter output. Once the qualified AC utility is
restored, the relay is energized, and the load is automatically reconnected to AC utility.
The Global LF Series Inverter is equipped with a powerful charger.
The overload capacity is 300% of continuous output for up to 20 seconds to reliably support tools and
equipment longer
Another important feature is setting the Battery priority via a DIP switch, and can be easily customized
which helps to extract maximum power from the battery in renewable energy systems.
Thus, the Global LF Series Pure Sine Wave Inverter is suitable for renewable energy systems, utility, RV,
marine and emergency appliances.
To get the most out of the power inverter, it must be installed, used and maintained properly. Please read the
instructions in this manual before installing and operating.
