SPECIFICALLY, PLEASE NOTE THAT THE INVERTER/CHARGER SHOULD NOT BE USED
IN CONNECTION WITH LIFE SUPPORT SYSTEMS OR OTHER MEDICAL EQUIPMENT OR
DEVICES. WE MAKE NO WARRANTY OR REPRESENTATION IN CONNECTION WITH
THEIR PRODUCTS FOR SUCH USES. USING THE INVERTER/CHARGER WITH THESE
PARTICULAR EQUIPMENTS IS AT YOUR OWN RISK.
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 for at least 20 minutes and get medical attention
immediately.
1.2.2 Never smoke or allow a spark or flame in vicinity of battery or engine.
1.2.3 Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery of
other electrical part 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 rechargeable batteries such as deep-cycle lead acid,
lead antimony, lead calcium gel cell, absorbed mat, and NiCad/NiFe or Lithium battery. Other types
of batteries may burst, causing personal injury and damage.
2 Introduction
2.1 General Information
SD 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 85%.
It is packed with unique features and it is one of the most advanced inverter/chargers in 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
endangering the equipment.
When the 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 SD Series Inverter is equipped with a powerful charger of up to 110Amps (for 4KW one).
The overload capacity is 300% of continuous output for up to 20 seconds to reliably support tools
