- The terminal is positive (+) and black terminal is negative (-).
- Insert the cables into the terminals and tighten allen nut to clamp the wires securely.
- 3-7-3. Before proceeding further, carefully check that cable you have just connected does tie negative terminal of inverter to the negative output power source.
- 3-7-4. Connect the cable from the negative terminal of the inverter to the negative terminal of the power source. Make a secure connection.
- 3-7-5. Set the power switch to the ON position. Check the meters and indicators on the front panel of the inverter. The voltage bar graph should indicate 11 to 14 volts (22 to 28V when 24V version is used) depending on the voltage of the power source....
- The other indicators should be off.
- 3-7-6. Set power inverter switch to the OFF position, the indicator lights may blink and the internal alarm may sound momentarily.
- This is normal. Plug the test load into the AC receptacle on the front panel of the inverter. Leave the test load switch off.
- 3-7-7. Set power inverter switch to the ON position and turn the test load On. The inverter should supply power to the load.
- If you plan to accurately measure the true output r.m.s. voltage of inverter, a meter such as FLUKE 45 BECKMAN 4410 or TRIPLETT 200 must be used.
- 8-1-1. Hardware design：
- This unit uses a 9-pin D connector and three of RS232 signal lines：
- RECEIVE DATA (RXD)：PIN2
- TRANSMIT DATA (TXD)： PIN3
- DATA TERMINAL READY (DTR)：PIN4
- 8-1-2. The connection between this unit and a computer is as follows：
- 8-1-3. The RS232 interface of this unit employs ASCll code to implement the asynchronous serial transmission control.
- The byte structure is START BIP – 8 BIT DATA-STOP BIT Baud rate：1200,2400,4800,(SET BY DIP-SW).
- Parity check ：NONE, not settable
- Data bit：8, not settable.
- Stop bit：1, not settable.
- 8-2-1. The Baud Rate of the RS232 interface is determined by S5 and S6 of DIP-SW, as shows in Appendix A.
- Note：You have to reset the unit after adjustment to activate the New settings.
- 8-2-2. Illustration of the RS232 operation：
- 8-2-2-1. RS232 command
- Command format：
- This unit uses high-level language commands with a CR (0DH) and a LF (0AH) as the end of the command.
- The system would interpret and execute the command only after these two characters are received.
- After the unit execute the command, it would send a response string to the computer.
- The response string is as follows：
- = > CR LF：Command executed successfully
- ? > CR LF：Command error, not accepted
- ! > CR LF：Command correct but execution error (e.g. parameters out of range)
- If the command needs any information from the unit, the unit would send the information back to the computer (with CR and LF) and then send the response string to the computer.
- 8-2-2-2. Command format
- This unit supports the following commands.
- There should always be a CR (0DH) and a LF (0AH) appended to the command while sending the command to his unit.
