Table 3-1. Recommended Sizes for Input
Conductors and Line Fuses
*Sized per National Code for 80 °C rated copper conductors @ 30 °C ambient. Not more than three
conductors in raceway or cable. Local codes should be followed if they specify sizes other than those
listed above.
3. INSTALLATION
A. LOCATION
A proper installation site is necessary for the power source to provide
dependable service. A proper installation site permits freedom of air movement
through the unit while minimizing exposure to dust, dirt, moisture, and corrosive
vapors. A minimum of 18 inches (46 cm) is required between the side and rear
panels of the power source and the nearest obstruction.
The selected site should also allow easy removal of the power source outer
enclosure for maintenance. See Table 2-1 for overall dimensions of the unit.
B. RECEIVING, UNPACKING AND PLACEMENT
When requesting information concerning this equipment, it is essential that
Item number, Serial number and Model number of the equipment be supplied.
a. Upon receipt, remove all packing material and carefully inspect for any
damage that may have occurred during shipment. Any claims for loss
or damage that may have occurred in transit must be filed by the
purchaser with the carrier. A copy of the bill of lading and freight bill
will be furnished by the carrier on request.
b. Remove the power source from the container. Remove all packing
materials. Check the container for any loose parts.
c. Check air passages at front and rear of cabinet, making sure that
packing material has not obstructed air flow through the power
source.
d. Install the lifting bolt furnished with the power sources into the top of the
unit.
e. After selecting an installation site, place the power source in the
desired location. The unit may be lifted either by using the lifting bolt
or by forklift truck. If a forklift is used for lifting the unit, be sure that
the lift forks are long enough to extend completely under the base.
C. PRIMARY (INPUT) ELECTRICAL CONNECTION
This power source is a three-phase unit and must be connected to a three-phase
power supply. It is recommended that the unit be operated on a dedicated circuit
to prevent impairment of performance due to an overloaded circuit.
INSTALLATION SECTION 3
For lifting purposes and for keeping
dust, moisture, and other foreign ma-
terial from entering the power source,
the lifting eyebolt must be fully tight-
ened with a tool.
Do not use filters on this unit as they
would restrict the volume of intake air
required for proper cooling. Output
ratings on this unit are based on an
unobstructed supply of cooling air
drawn over its internal components.
Warranty is void if any type of filtering
device is used.
