3.02 Site Selection
Select a clean, dry location with good ventilation and ad-
equate working space around all components.
CAUTION
Operation without proper air flow will inhibit
proper cooling and reduce duty cycle.
The Power Supply is cooled by air flow into the unit
through the bottom and side panels. The fan moves the
air through the unit forcing the air out the back panel.
Air flow must not be obstructed. At least 2 feet (0.61 m)
of clearance should be provided on all sides.
A source of three-phase power and a source of gases with
pressure regulators are required.
Review the safety precautions in the front of this manual
to be sure that the location meets all safety requirements.
3.03 Unpacking
Each component of the system is packaged separately and
protected with a carton and packing material to prevent
damage during shipping.
1. Unpack each item and remove all packing mate-
rial.
2. Locate the packing list(s) and use the list to iden-
tify and account for each item.
3. Inspect each item for possible shipping damage. If
damage is evident, contact your distributor before
proceeding with installation.
3.04 Removing Skid
The base of the Power Supply is secured to the skid with
bolts and hex nuts. Remove the Power Supply from the
skid per the following procedure:
1. Turn the supplied lifting eye bolt all the way into the
threaded socket on top of the unit and tighten it se-
curely.
