Fork Lift Trucks:
A single fork lift truck may be used on drives not exceeding ten feet in length if the lift truck has sufficient
lifting capacity. Larger drives can be moved with two forklift trucks operating in tandem.
1. Insert forks into openings of shipping skids from the rear of the drive.
2. Carefully balance the drive on the forks because the drives are usually heavier at one side.
3. Use safety straps when handling to steady the drive while moving.
Storage
If it is necessary to store the drive be certain to store in a clean dry dust free area.
Storage temperature should be maintained between -5 and 40 degrees C. If storage temperature
fluctuates or if humidity exceeds 85%, space heaters should be used to prevent condensation. The drive
should be stored in a heated building having adequate air circulation. The drive must never be stored
outdoors.
Installation Site
When selecting the installation site, the following conditions should be considered:
A) The operating ambient temperature must be between 0

C (32

F) and 40

C (104

F) for NEMA
Type 1 enclosures.
B) The relative humidity must not exceed 95% non-condensing. Excessive humidity can cause corrosion
or excessive dirt build-up leading to possible electrical problems.
C) The equipment must be kept clean. Dust build-up inside the enclosure inhibits proper cooling and
decreases the system reliability.
