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 ventilation cover when
the temperature e40
°
C [+104
°
F].)
— The relative humidity is between 20% and 90%. 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.
— The drive should be installed at an elevation below
1000 meters (3281 feet). Installation above 1000
meters (3300 feet) 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.
— Vibration should be less than 0.6G.
Installation Mounting Clearance
CAUTION:
Because the ambient temperature greatly
affects drive life and reliability, do not install the drive in any
location that exceeds the allowable temperatures.
— Install at a sufficient distance from other equipment,
walls, or wiring ducts as shown in Figure 3-1 (these
clearances are required to allow the heat generated by
the drive to escape).
— 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.)

CAUTION:
The mounting wall for the drive must be constructed of
heat resistant material because during operation, the
temperature of the Inverter's cooling fins rises to approxi-
mately 90 degrees C (194
°
F).
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 tempera-
ture from rising.
— Mounting screws or bolts should be of appropriate size
for weight of drive.
— See the appropriate view in Figure 3-2 for the location
of mounting holes.
— After removing the knockouts in the wiring lead in
plate, install the rubber bushings supplied to prevent
cable damage and to minimize dust entry.
