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.
INSTALLATION Unpacking and Inspection Carefully unpack the inverter/charger from its shipping carton. Verify all of items list below are present. Please call customer service if any items are missing. The unit 1 user’s manual Basic Configuration The following illustrations show basic applications for PowerWalker Inverter 3000 PSW. They include the following configurations: Utility Backup.
EN PowerWalker Inverter 3000 PSW 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.
Batteries The unit support 24volt battery bank. Please refer to figure 3 to wiring battery correctly. Before proceeding, ensure you have appropriate size batteries for this inverter. The unit can use flooded lead-acid, or sealed GEL/AGM lead-acid batteries so ensure that your batteries are in one of these categories. The battery must be wired to match the units DC input voltage specifications. Suggest battery capacity not smaller than 100AH.
Battery Cable Connection Observe Battery Polarity! Place the ring terminal of DC cable over the bolt and directly against the unit’s battery terminal. Tighten the M6 screw with 5-8 Nm. Do not place anything between the flat part of the Backup System terminal and the battery cable ring terminal or overheating may occur.
AC Connections Installation should be done by a qualified electrician. Consult local code for the proper wire sizes, connectors and conduit requirements. EN On the left of rear chassis is the AC hardwire cover. Two three-station terminal block is provided to make the AC connections. The terminal block is used to hardwire the AC input, AC output, and ground. The National Electrical Code requires that an external disconnect switch be used in the AC input wiring circuit.
