SAFETY PRECAUTIONS
It is mandatory to read the following precautions before manipulating the STR−ECS640A−GEVB unit.
- When connecting an oscilloscope probe to EVB unit the probe’s ground needs to be isolated. Failure to do so may result in personal injury or death.
- STR−ECS640A−GEVB unit contains DC bus capacitors which take time to discharge after removal of the main supply. Before touching the EVB, wait ten minutes for C3 and C5 capacitors to discharge to safe voltage levels. Failure to do so may result in personal injury or death.
- Only personnel familiar with the drive and associated machinery should plan or implement the installation, start−up and subsequent maintenance of the system. Failure to comply may result in personal injury and/or equipment damage.
- The surfaces of the heat sink may become hot, which may cause injury.
- STR−ECS640A−GEVB unit contains parts and assemblies sensitive to Electrostatic Discharge (ESD). ESD control precautions are required when installing, testing, servicing or repairing this unit’s parts or assemblies. ESD control procedures not followed may lead to component damage. If you are not familiar with electrostatic control procedures, refer to applicable ESD protection handbooks and guidelines.
- STR−ECS640A−GEVB incorrectly applied or installed, can result in component damage or reduction in product lifetime. Wiring or application errors such as under sizing the motor, supplying an incorrect or inadequate AC supply or excessive ambient temperatures may result in system malfunction.
- Remove and lock out power from STR−ECS640A−GEVB unit before you disconnect or reconnect wires or perform service. Wait ten minutes after removing power to discharge C3 and C5 bus capacitors. Do not attempt to service the drive until the bus capacitors have discharged to zero. Failure to do so may result in personal injury or death.
- Voltage doubler configuration is the default STR−ECS640A−GEVB unit configuration and can be used only with 120Vrms AC input. The use of voltage doubler configuration at 230Vrms AC input may result in personal injury or death.

To set up the STR-ECS640A-GEVB unit for 230Vac supply, follow these steps:
- If the unit is being powered with 120Vac, you may skip to step 3.
- For 230Vac AC mains supply, make the following hardware configuration changes:
- Remove the C3 (680 mF / 250 V capacitor).
- Add the J7 jumper as indicated in the picture.
- Remove the J6 jumper.
