3-12 Commissioning Procedures

1560E-UM050B-EN-P - June 2013

Table 3.B – Input Voltage Ranges

Tap Voltage Range MV Ratio

D 800 – 1449 V 1020

C 1450 – 2499 V 390

B 2500 – 4799 V 165

A 4800 – 7200 V 105

The MV ratios shown above are nominal values and may be fine tuned to

achieve better accuracy on the display of the SMC-Flex control module.

While running the motor in bypass mode, compare the voltage displayed on

the control module to a known accurate meter connected to the same source

voltage as the motor the MV SMC-Flex is controlling. Parameter 106, MV

Ratio, may be changed up or down to match the Flex display to the external

meter. A small change in ratio can make a large change in the display, so 5

units at a time is recommended. Increasing the ratio will decrease the

displayed voltage, and visa versa.

Start-Up 1. Remove any temporary jumpers or grounding devices used during

commissioning.

2. Check that all tools are removed from the equipment. Any tools or

hardware used or dropped during installation and commissioning must

be retrieved and accounted for.

3. Check that all barriers or covers removed during installation or com-

missioning have been securely mounted.

4. Close and secure all doors, and verify function of all interlocks that

prevent access to medium voltage compartments when the unit is

energized.

5. The controller is ready to power the motor.
