3-12 Basic Installation MN1902
Note: Power to single phase models may be derived by connecting two phases of an
appropriate three-phase supply (L1 and L2 for example). When supplying AC
power in this way, the voltage between the two phases must not exceed the rated
input voltage of the FlexDrive
II . A two pole breaker must be used to isolate both
lines. Fuses must be fitted in both lines. Circuit breaker or fuse are not supplied.
For CE compliance, see Appendix C.

Note: Metal conduit or shielded cable should be used. Connect conduits so the use of a
line reactor or RC device does not interrupt EMI/RFI shielding.
3.4.5 Power supply filters
To comply with EEC directive 89/336/EEC, an AC power filter of the appropriate type must be
connected. This can be supplied by Baldor and will ensure that the FlexDrive
II complies with
the CE specifications for which it has been tested. Table 1 lists the appropriate filters:
