• Maintain a storage temperature between –20...65 °C (-4...149 °F).
Occasionally, liquid-cooled drives use coolant that has a freezing point
higher than -20 °C (-4 °F). Check the freeze point of the coolant on the
coolant drum label and ensure that the storage temperature remains above
that point. Relative humidity must not exceed 95%, non-condensing.
Rockwell Automation recommends that you store the drive in a heated/
climate-controlled building with regulated air circulation to avoid damage.
• Remove all packaging from the drive for storage to prevent condensation
from damaging the equipment.
• Use factory-installed space heaters to prevent condensation if storage
temperature fluctuates or if humidity exceeds 85%.
• Medium voltage enclosures are designed for indoor use and do not ship
with sufficient packaging for outdoor storage. Ensure that you provide
adequate protection for the equipment if storing it outside. Install
temporary electrical heating to prevent condensation. Space heaters rated
at approximately 150 W per cabinet suit most enclosures. To avoid a fire
hazard, remove any loose packing or flammable material from the drive
before using the space heaters.
Planning Ensure that you can move the equipment into place. Check that all ceiling, door
heights, and turning distances are adequate. Prepare and verify the level of the
intended drive site.
Leveling
Prepare a level concrete surface for the equipment at the final installation site.
Verify that the siting surface is level to +/- 1 mm per meter (+/-0.036 in. per
36 in.) in all directions.
Once you position the drive, test the level. If necessary, shim the equipment with
sheet metal to level the mounting. If joining shipping splits, level and shim prior
to joining the cabinets to avoid torquing or twisting the cabinets on a non-level
surface.
IMPORTANT Export-crated drives include a two-month supply of desiccant (from date of
shipment). If you require desiccant for longer storage times, please specify the
amount when ordering. You can leave the drive in the export crating until the
desiccant expires.
IMPORTANT Improperly leveled sites may inhibit proper set-up by introducing
misalignments in joining hardware or interfering with latch and interlock
operations.
