INSTALLATION ENVIRONMENT
Install the Drive in an indoor location that meets the
following requirements:
— The ambient temperature is between -10° C and
+50° C (+14° F to +122° F). Remove the ventila-
tion covers when the temperature exceeds +40° C
[+104° F].
— The relative humidity is between 20% and 95%.
Avoid any location subject to condensation, freezing,
or where the Drive would come in contact with water.
— Do not install in any location subject to direct sunlight,
dust, corrosive gas, inflammable gas, or oil mist.
— Vibration should be less than 0.6G.
— The Drive should be installed at an elevation below
1000 meters (3281 feet). For installation above 1000
meters (3300 feet) the Drive will need to be derated
1% per 333 feet.
Example: 5 HP, 460 VAC, output current 9 amps.
Application altitude 3900 feet.
% derate = x 1% = 1.8%
(9 amps) x = 8.84 amps
derated output current.
Motor derate may also be required,
contact motor manufacturer.
INSTALLATION MOUNTING
CLEARANCE
— Install the Drive perpendicular to the ground and
with the lettering right side up. (If the Drive is
installed upside-down or horizontally, heat build-
up will occur.)
— Mounting screws or bolts should be of appropriate
size for weight of Drive.
— See the appropriate figures on pages 3-2 and
3-3 for the location of mounting holes.
— After removing the knockouts in the wiring lead-in
plate, install the rubber bushings supplied to pre-
vent cable damage and to minimize dust entry.
— Install at a sufficient distance from other equip-
ment, walls, or wiring ducts as shown in Figure
3-1 (these clearances are required to allow the
heat generated by the Drive to escape).
CAUTION: Because the ambient temperature greatly
affects Drive life and reliability, do not install the Drive in
any location that exceeds the allowable temperatures.
NOTE:
When installing two or more Drives in close
proximity, allow sufficient space as shown in Figure 3-1
and install them in a horizontal row. If they must be
installed in a vertical column, at least 19.7 inches (50cm)
internal space must be provided between each one or a
ventilation baffle should be provided to prevent the
ambient temperature from rising.
CAUTION: The mounting wall for the Drive must be
constructed of heat resistant material because during
operation, the temperature of the Drive's cooling fins
rises to approximately 90 degrees C (194° F).
