D. WARNING AND SAFETY
1) Read the manual before connecting this inverter and keep it for future reference.
2) While opening the product package, please check the integrity of the product and accessories. If
there is any problem, please do not use it.
3) While connecting and using for the first time, if there is smoke or explosion sound in the product,
please stop using immediately and disconnect the product from the battery and electrical appliances.
This may be caused by damage during the transportation or due to moisture during storage in the
warehouse before delivery. Please contact your seller in time.
4) During daily use, if there is smoke or explosion sound in the product, please don’t worry,this is due to
the internal fuse protection of the product . Please do not disassemble it by yourself. Please stop
using the product immediately. Disconnect the product from the battery and electrical appliances.
Contact the seller in time and only with seller’s agreement a hired professional personnel can
disassemble the product . Otherwise, it may cause electric shock, fire and serious personal injury
5) Do not put the inverter under direct sun light or near a heating source.
6) The case of inverter will get hot during using. Do not allow flammable materials such as clothing,
sleeping bags, carpet or any other flammable materials to touch the inverter. The heat from the
inverter can damage these items.
7) The power inverter is designed to be used with a negative ground electrical system! Don't use with
positive ground electrical systems (the majority of modern automobiles, RVs, trucks and boats are
negative ground).
8) Do not disassemble the unit randomly: it may cause fire or electric shock.
9) This device should only be serviced by a qualified technician. This item does not have any service-
able parts.
10) Prevent body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerator
enclosures during installation.
11) Do not operate the inverter if under the influence of alcohol or drugs. Read warning labels on
prescriptions to determine if your judgement or reflexes are impaired while taking drugs. If there is
any doubt, do not operate the inverter.
12) People with pacemakers should consult their physician(s) before using this product. Electromagnetic
fields in close proximity to a pacemaker could cause interference to or failure of the pacemaker.
13) Keep the inverter well-ventilated. Do not place any objects on top of or next to the inverter or allow
anything to cover the cooling fans;inverter will bel overheating, causing a potential fire hazard and/or
damage to the inverter. Leave adequate ventilation space underneath the inverter as well; thick
carpets or rugs can obstruct air flow, causing the inverter to overheat.
14) Avoid unintentional starting. Be sure the switch is in the OFF position when not in use and before
plugging in any appliance.
15) Keep inverter away from children. Don't install the inverter where it is accessible to children.
16) The power inverter will output the same AC power as utility power, please treat the AC outlets as
carefully as you would your home AC outlets. Do not put anything other than an electrical appliance
into the output terminal. It may cause shock or fire.
17) This product cannot be used for medical and life support equipment.
B. INSTRUCTION
The GIANDEL Power inverter product line is used for back-up power. The pure sine product line is ideal
for sensitive equipment and provides clean power, which is more efficient for back-up power applica-
tions. It converts DC (direct current/car battery) power into AC (alternating current) power that can be
used for running a wide variety of tools and appliances under rating power. This inverter is perfect for
providing mobile power in cars, boats and work trucks. The inverter can also be utilized as a back-up
source of electricity in the event of an electrical failure or for several off-grid applications such as
camping or in your RV.
C. Please read this instruction manual carefully and make sure your inverter is installed properly
before using.
