3.1 Installation Site Checklist
•
The drive relies on the ambient air for cooling.
Observe the limits on ambient air temperature for
optimal operation
•
Ensure that the installation location has sufficient
support strength to mount the drive
•
Keep the drive interior free from dust and dirt.
Ensure that the components stay as clean as
possible. In construction areas, provide a
protective covering. Optional IP54 (NEMA 12)
enclosures may be necessary.
•
Keep the manual, drawings, and diagrams
accessible for detailed installation and operation
instructions. It is important that the manual is
available for equipment operators.
•
Locate equipment as near to the motor as
possible. Keep motor cables as short as possible.
Check the motor characteristics for actual
tolerances. Do not exceed
•
1000 ft [300 m] for unshielded motor
leads
•
500 ft [150 m] for shielded cable.
3.2 Adjustable Frequency Drive and Motor
Pre-installation Checklist
•
Compare the model number of unit on the
nameplate to what was ordered to verify the
proper equipment
•
Ensure each of the following are rated for the
same voltage:
Line power
Drive
Motor
•
Ensure that drive output current rating is equal to
or greater than motor full load current for peak
motor performance.
Motor size and drive power must match
for proper overload protection.
If drive rating is less than motor, full
motor output cannot be achieved.

Illustration 3.1 Top and Bottom Cooling Clearance
DET-759A
To provide cooling airflow, mount the unit to a
solid flat surface or to the optional backplate (see
3.3.3 Mounting)
Top and bottom clearance for air cooling must be
provided. Generally, 4–10 in [100–225 mm] is
required. See Illustration 3.1 for clearance
requirements
Improper mounting can result in overheating and
reduced performance.
Derating for temperatures starting between 104°F
[40°C]) and 122°F [50°C] and elevation 3,300 ft
[1,000 m] above sea level must be considered.
See the equipment Design Guide for detailed
information.
