T ightening torque for terminal block connections is 0.5-0.6Nm (4.4-5.3 lb-in). The threaded
hole in the top of the enclosure is for protective earth/ground connections. The threaded hole
in the bottom of the enclosure (if present) may be used as an additional functional
earth/ground connection for signals on connector X3. It may also be used to attach strain relief
clamps. The holes are threaded for M4 bolts no longer than 12mm (0.47 in) in length. Longer
bolts may short circuit the electrical components inside the FlexDrive

WARNING: Drives with part numbers FDH2A15... or FPH2A15... have two
additional terminals on the X1 connector labeled Vcc+ and Vcc-.
The full output bus voltage is present on the these terminals so do not
make any connection to them.
Note: For CE compliance, a three- phase AC filter must be connected between the AC
power supply and the FlexDrive

. If local codes do not specify dif ferent
regulations, use at least the same gauge wire for earth/ground as is used for L
and N.
