INSTALLATION
Safety Precautions
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 500-I for parallel-
ing, and outdoor operations without rain sheltering is
not recommended.
STACKING
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.
