Assembling the Current Sensor Cylinder Busbars in D1h/D3h/D5h/D6h Drives
WARNING
NOMEX SLEEVES REQUIRED
The Nomex sleeves are required to maintain proper electrical protection. Failure to install the Nomex sleeves can result in
personal injury or equipment damage.
•
Do not discard the Nomex sleeves.
Use the following steps to assemble the current sensor cylinder busbars in D1h/D3h/D5h/D6h drives. Refer to
Illustration 1.2
.
1.
Place the 3 Nomex sleeves over the cylinder busbars,
1 per busbar. Place the sleeve with the red marking
on the short busbar.
2.
Insert 3 M6x90 screws through the center of the
busbars and place the busbar mounting frame, 1
screw per busbar. The busbar with the red marking is
the V busbar and is mounted in the middle.
3.
Retain 3 M6x16 screws to fasten the busbar
mounting frame in the drive when installing the
current sensors. The cylinder busbars are inserted
through the centers of the current sensors. Refer to
300 A Current Sensor Kit for D1h/D3h/D5h/D6h Drives
installation instruction.
