Toshiba VFS5 Series Operation Manual page 9

13) Use separate metal conduits for routing the input power, output power, and control circuits.
14) If the factory provided door or NEMA 1 enclosure is removed from the drive, then, before operating,
it must be provided with an alternate enclosure of NEMA 1 minimum rating.
15) Do not connect control circuit terminal block return connections marked CC to inverter earth ground
terminals marked GND(E). See Standard Power Connection Diagrams on page 18 and Typical
Control Wire Connection Diagrams on page 20 for locations.
16) If a secondary Magnetic Contactor (MC) is used between the inverter output and the load, it should
be interlocked so the ST-CC terminals are disconnected before the output contactor is opened. If
the output contactor is used for bypass operation, it must also be interlocked so that commercial
power is never applied to the inverter output terminals (U,V,W).
17) Power factor improvement capacitors or surge absorbers must not be installed on the drive's output.
18) For those applications requiring extended ASD to motor cable lengths exceeding the chart
recommendation shown on page 17, a output voltage filter should be added.
