Vertical Suspension of the Drive (CIMR-A2A0360, 2A0415, 4A0250 to 4A1200)
CIMR-A2A0360, 2A0415, 4A0250 to 4A0675
When vertical suspension of the drive is required in an enclosure panel, the orientation of the eye bolts for these drive
models can be easily changed by turning the eye bolts counterclockwise 90 degrees.

When suspending the CIMR-A4A0930 or 4A1200 drive with wires, make sure to follow the procedure described
below.
Note: Use a wire long enough to ensure an angle of suspension that is at least 50 degrees. If not, the maximum allowable load of the eye
bolts cannot be guaranteed. Refer to Figure 2.8 for details.
1. Remove the four eye bolts from the drive side panels, and screw them into the holes on the top panel.

2. Pass wire through the holes of the four eye bolts.

3. Take up the slack in the wires gradually with a crane, and when the wires are confirmed to have stretched tight,
hoist the drive.
4. When ready to install the drive in the enclosure panel, lower the drive. Halt lowing once when the drive has
reached near the floor, and then lower the drive again very slowly.
