2 Introduction: The power inverter series are the member of the most advanced line of mobile AC power systems available. To get the most out of the power inverter, it must be installed and used properly. Please read the instructions in this manual before installing and using this model. 2-1 Front Panel Operation: 2-1-1 Front view: 2-1-2 ON / OFF switch:...
2-2 Rear Panel Operation: 2-2-1 Ventilation openings: Do not obstruct, allow at least 3 inch for air flow. 2-2-2 AC input switch: This switch is to be operated by qualified personnel only. 2-2-3 Battery terminals: Connect to 24V/48V/110V/220V battery or other 24V/48V/110V/220V power Source. 【+】is positive,【-】is negative.
See Appendix A for RS232 protocol • WARNING! Any damages caused by using incorrect RS232 cable will be outside of our warranty scope. If you are not sure which one is correct RS232 cable, please purchase the correct RS232 cable from us directly.
2-3-3 Safe – Do not install in a battery compartment or other areas where flammable fumes may exist, such as fuel storage areas or engine compartments. 2-3-4 Ventilated – Allow at least one inch of clearance around the inverter for air flow. Ensure the ventilation openings on the rear and bottom of the unit are not obstructed.
2-4-3 Before proceeding further, carefully check that cable you have just connected negative terminal of inverter to the negative output power source. CAUTION! Reverse polarity connection will blow a fuse in inverter and may permanently damage the inverter. Damage caused by reversing polarity connection is not covered by our warranty.
230V models: There is no connection made inside the YK-PSW5KVA/E Inverter from either the line or neutral conductor to the safety ground. Ground Fault Circuit Interrupters (GFCI’S): Installations in Recreational Vehicles (for North American approvals) will require GFCI protection of all branch circuit connected to the AC output of the hardwire terminal equipped inverter.
Increasing your DC cable size will help improve the situation. Our company recommends the following cables for optimum inverter performance Model No Wire AWG Inline Fuse RM -PSW245KVA/E #4/0 300A RM -PSW485KVA/E #2/0 200A RM -PSW1105KVA/E 100A RM -PSW2205KVA/E Also, use only high quality copper wiring and keep cable length short from 3-6 feet. 2-7 Inverter Operation: To operate the power inverter, turn it on using the ON/OFF switch on the front panel.

2-7-11 Overload protection indicator: (OLP) The overload indicator indicates that the power inverter has shut itself down. When output voltage over continue power, then must return to operate manually. Cooling fan working code: Cooling fan of inverter is through detecting output power and over temperature situation to work.
4 Troubleshooting guide: WARNING! Do not open or disassemble the inverter. Attempting to service the unit yourself may result in a risk of electrical shock or fire. Common problems – television interference: Operation of the power inverter can interfere with television reception on some channels, If this situation occurs, the following steps may help to alleviate the problems.
5 Warranty : We warrant this product against defects in materials and workmanship during warranty period and will repair or replace any defective power inverter when directly returned (postage paid) to us. This warranty will be considered void if the unit has suffered any obvious damage by natural and man-made factors, or alteration either internal or external and does not cover damage arising from improper use such as plugging the unit into an unsuitable power sources attempts to operate products with excessive power consumption requirement, or use in...
6-2 Precautions When Working with Batteries 6-2-1 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 lease 20minutes and get medical attention immediately. 6-2-2 NEVER smoke or allow a spark or flame in vicinity of battery or engine.
