Page 3: Warnings
Do not remove the digital operator while the mains supply is switched on. The printed cir- cuit board must also not be touched while the inverter is connected to the power. -
Page 4: Safety Precautions And Instructions
The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from the power. It is therefore necessary to wait for this time before opening its covers. All of the main cir- cuit terminals may still carry dangerous voltages. -
Page 5: Emc Compatibility
OYMC frequency inverters do not necessarily have to be installed in a switch cabinet. It is not possible to give detailed instructions for all of the possible types of installation. This manual therefore has to be limited to general guidelines. - Page 6 Use a power cable with well-grounded shield. For motor cables up to 50 meters in length use shielded cables. Arrange all grounds so as to maximize the area of the end of the lead in contact with the ground terminal (e.g. metal plate).

Page 7: Installation
Observe the following precautions when mounting the Inverter: • Install the Inverter in a clean location which is free from oil mist and dust. It can be installed in a totally enclosed panel that is completely shielded from floating dust. -

- Page 12 Sinking/Sourcing Mode (NPN/PNP Selection) The input terminal logic can be switched over between sinking mode (0-V common, NPN) and sourcing mode (+24V common, PNP) by using the jumper CN5. An external power supply is also supported, providing more freedom in signal input methods.

Page 22: Troubleshooting
Faults and Alarms indicate unsusal inverter / application conditions. An alarm does not necessarily switch of the inverter but a message is displayed on the keypad (i.e. a flashing alarm code) and an alarm output can be generated at the multi-function outputs (H2-01 and H2-02) if programmed. -
Page 23: Operator Programming Errors
The Inverter does not operate until the parameter setting is corrected; however, no other alarm or fault output will occur. If an OPE occurs, change the related parameter by checking the cause shown in the table below. When an OPE error is displayed, press the ENTER key to see U1-34 (OPE Detected). -
