2. Transport
There are two methods for transporting the enclosure, by crane or by pushing on a loading
cart. Check that all doors and delivered devices are secured prior to transporting.
2.1 Cautionary Items During Transport
• Do not push or pull the enclosure on a floor (concrete, etc.) unless there is a steel slid-
ing surface or grooved channel base.
• Do not tilt or rock the enclosure.
• Do not apply excessive vibration or shock to the enclosure during transport (4.9 m/s
2
(0.5G) or less).
2.2 Cautionary Items in Suspending the Unit from Cables
• When suspending the unit, use cables that with a strength to match the mass of the
unit.
• Use cables with a length that will assure a suspension angle of 60° or greater as shown
in Figure 2.1 Proper Cable Suspension . The allowable suspension load of the suspen-
sion bracket cannot be assured if the suspension angle is smaller than this.
• Attach a cable to each of the suspension holes on the suspension bracket. Do not sus-
pend the unit as shown in Figure 2.2 Example of Improper Cable Suspension .
• Prevent shock during suspension. If lifting by a crane after attaching the wires, gradu-
ally take up slack until the cables are stretched, the lift after verifying that the cables
are taught. Do not lift (or lower) suddenly. When lowering to the floor, stop just prior
to contacting the floor, then gradually lower so as not to apply any shock to the enclo-
sure.
• Use a qualified operator when transporting the unit by crane. Failure to due so
my result in injury or dropping of unit.
