2 Installation2.1 Installation Site Checklist• The adjustable frequency drive relies on theambient air for cooling. Observe the limitationson ambient air temperature for optimal operation• Ensure that the installation location has sufficientsupport strength to mount the adjustablefrequency drive• Keep the adjustable frequency drive interior freefrom dust and dirt. Ensure that the componentsstay as clean as possible. In construction areas,provide a protective covering. Optional IP54(NEMA 12) enclosures may be necessary.• Keep the manual, drawings, and diagramsaccessible for detailed installation and operationinstructions. It is important that the manual isavailable for equipment operators.• Locate equipment as near to the motor aspossible. Keep motor cables as short as possible.Check the motor characteristics for actualtolerances. Do not exceed• 300 m (1000 ft) for unshielded motorleads• 150 m (500 ft) for shielded cable.2.2 Adjustable Frequency Drive and MotorPre-installation Checklist• Compare the model number of unit on thenameplate to what was ordered to verify theproper equipment• Ensure each of the following are rated for thesame voltage:Line powerAdjustable frequency driveMotor• Ensure that the adjustable frequency drive outputcurrent rating is equal to or greater than motorfull load current for peak motor performanceMotor size and adjustable frequencydrive power must match for properoverload protectionIf adjustable frequency drive rating isless than motor, full motor outputcannot be achieved2.3 Mechanical Installation2.3.1 Cooling• To provide cooling airflow, mount the unit to asolid flat surface or to the optional backplate (see2.3.4 Mounting)• Top and bottom clearance for air cooling must beprovided. Generally, 100–225 mm (4–10 in) isrequired. See Figure 2.1 for clearancerequirements• Improper mounting can result in overheating andreduced performance.• Derating for temperatures starting between 104°F[40°C] and 122°F [50°C] and elevation 3300 ft[1000 m] above sea level must be considered.
