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.
1.4.4 Installing Brake Terminal Block (optional)
If the optional brake is present, reinstall the brake terminal
block using the following steps.
1.
Position the optional brake terminal block in the
drive.
2.
Secure 2 M8 nuts (T40) in the terminal block.
3.
Fasten the R (-) terminal using 1 M4x8 thread-forming
screw (T20) at the terminal block, and 1 M8 nut
(T40).
4.
Fasten the R (+) terminal using 1 M4x8 thread-
forming screw (T20) at the terminal block, and 1
screw (T40).
5.
Reconnect the brake wiring.
1.4.5 Installing Mains Input Terminal Block
To install the mains input terminal block, use the following
steps. Refer to
Illustration 1.5
.
1.
Place the mains input terminal block in position by
sliding it under the 2 metal retaining clips.
2.
Secure 2 screws (T25) at the bottom of the mains
input terminal block.
3.
Reconnect any customer input wiring, and replace
the R/S/T terminal label.
1.4.6 Installing AC Input Busbars
To install the AC input busbars, use the following steps. The
AC input busbars can look different when the drive includes
extra input options, such as an RFI filter or mains fuses.
Illustration 1.2
shows the drive with no input options.
Illustration 1.3
The next procedure differs based on options present in the
drive. Select the appropriate procedure for the drive:
•
No options
•
Mains fuses only
•
RFI filter only
•
Mains fuses and RFI filter
