LOCATION
The machine should be located in a clean, dry place where there is free circulation of clean air such that air movement in through the front and out through the back will not be restricted. Dirt and dust that can be drawn into the machine should be kept to a minimum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shut- down of the machine.
APPLICATION LIMITATIONS
There are no provisions on the CV
STACKING
WARNING
FALLING EQUIPMENT can cause
injury.
•Do not lift this machine using lift bale if it is equipped with a heavy accessory such as trailer or gas cylinder.
•Lift only with equipment of adequate lifting capacity.
•Be sure machine is stable when lifting.
•Do not stack more than three high.
•Do not stack the CV
The units may be stacked three high by observing the following safety precautions.
1.Make sure the first or bottom unit is setting on a level, well supported surface.
2.The units must be stacked with their fronts flush, making sure the two holes in the base rails of the unit being stacked on top are over the two holes located on the top front corners of the unit it is being stacked on. Fasten the units together with 5/16 bolts, nuts and lockwashers through these holes.
3.Remove fastening bolts before lifting unit off stacks.
Input Power Connections
By removing the rear access panel the three phase input power is connected to the three line terminals on the input contactor, and the earth grounding lead to the grounding terminal on the input box floor marked with the 
symbol. Install the reconnect panel jumper links for the proper input voltage per the diagram pasted inside the access panel cover.
