6. CAUTION --Battery are not already installed by the supplier only a qualified professional (e.g. service
person) may install the Inverter.
7. WARNING: WORKING IN VICINITY OF A LEAD ACID BATTERY IS DANGEROUS.
BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. Provide ventilation
to outdoors from the battery compartment. The battery enclosure should be designed to prevent
accumulation and concentration of hydrogen gas in “pockets” at the top of the compartment. Vent the
battery compartment from the highest point. A sloped lid can also be used to direct the flow to the vent
opening location.
8. NEVER charge a frozen battery.
9. No terminals or lugs are required for hook-up of the AC wiring. AC wiring must be no less than 12 AWG
gauge copper wire and rated for 75oC or higher. Battery cables must be rated for 75oC or higher and
should be no less than table 1. Crimped and sealed copper ring terminal lugs with a 5/16 hole should
be used to connect the battery cables to the DC terminals of the unit. Soldered cable lugs are also
acceptable.
10. Be extra cautious when working with metal tools on, or around batteries. The potential exists to drop a
2
EN
tool and short-circuit the batteries or other electrical parts resulting in sparks that could cause an
explosion.
11. No AC or DC disconnects are provided as an integral part of this unit. Both AC and DC disconnects
must be provided as part of the system installation. See INSTALLATION section of this manual.
12. Fuses (F40AL, 32VDC*6) are provided as the over current protection of the battery supply.
13. GROUNDING INSTRUCTIONS -This battery charger should be connected to a grounded permanent
wiring system. For most installations, the Ground Lug should be bonded to the grounding system at one
(and only one point) in the system. All installations should comply with all national and local codes and
ordinances.
14. AVOID AC output short-circuit; avoid DC input short-circuit and do not connect the mains while DC
input short-circuit
15. Warning: The maintenance information is only to service persons
Personal Precautions
1. Someone should be within range of your voice to come to your aid when you work near batteries.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3. Wear complete eye protection and clothing protection. Avoid touching eyes while working near
batteries. Wash your hands when done.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eyes,
immediately flood eyes with running cool water for at least 15 minutes and get medical attention
immediately.
5. Baking soda neutralizes lead acid battery electrolyte. Keep a supply on hand in the area of the
batteries.
6. NEVER smoke or allow a spark or flame in vicinity of a battery or generator.
7. Be extra cautious when working with metal tools on, and around batteries. Potential exists to
short-circuit the batteries or other electrical parts which may result in a spark which could cause an
explosion.
8. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with
battery. Battery can produce short-circuit current high enough to weld a ring, or the like, to metal
causing severe burns.
9. If a remote or automatic generator start system is used, disable the automatic starting circuit and/or
disconnect the generator from its starting battery while servicing to prevent accidental starting during
servicing.

Basic Configuration
The following illustrations show basic applications for PowerWalker Inverter 3000 PSW.
They include the following configurations:
Utility Backup. see figure 1
Renewable Energy Source And a Generator, see figure 2
Consult with your system design for other possible configurations depending on site or code
requirements.
Figure 1 Utility Backup

EN
Figure 2 Renewable Energy Source
PowerWalker Inverter 3000 PSW can feeds almost all kinds of appliances from home to office
environment, including motor characteristic appliances like tube light, fan, refrigerator and Air conditioner.
Note: Appliances like Air conditioner needs at least 3 minutes to restart in case of a power shortage
occurs in a way that the power turns off then back on again rapidly (time is required to balance the
refrigerant gas in inside circuit); so in order to protect your Air conditioner, please consult the Air
conditioner manufacturer whether they have already provided time delay function before installing.
Otherwise, Inverter will trig overload fault and shut off its output to protect your appliance but
sometimes it is not enough and your Air conditioner can be damaged internally beyond repair.
