1.4.3 Installing Motor Terminal Block
To install the motor terminal block, use the following steps.
Refer to Illustration 1.5.
1. Position the motor terminal block by sliding it
upward under the 2 metal retaining clips.
2. Fasten 2 screws (T25) at the lower end of the motor
terminal block.
3. Place 3 Nomex tubes in the drive, 1 in the center of
each current sensor. Place the shorter tube (marked
with a red line) through the middle current sensor.
4. Place 3 cylinder busbars in the drive, 1 inside each
Nomex tube. Place the shorter busbar through the
middle Nomex tube.
5. Replace the U motor busbar:
5a Slide the insulator sleeve over the U busbar.
5b Fasten 1 screw (T30) in the current sensor
end of the busbar.
5c Fasten 1 thread-forming screw (T25) in the
middle of the busbar.
6. Replace the V motor busbar:
6a Fasten 1 screw (T30) in the current sensor
end of the busbar. Note that the V bolt is
shorter than the U/W bolts.
6b Fasten 1 thread-forming screw (T25) in the
middle of the busbar.
7. Replace the W motor busbar:
7a Fasten 1 screw (T30) in the current sensor
end of the busbar.
7b Fasten 1 thread-forming screw (T25) in the
middle of the busbar.
8. Position the EMC shield between the mains input
terminal block and motor terminal block and secure
with 2 screws (T25).
9. Reconnect wiring to motor terminals, and replace the
U/V/W terminal label.
