2 Installation

2.1 Installation Site Check List

•
The drive relies on the ambient air for cooling.
Observe the limitations 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 IP55 (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
•
300m (1000ft) for unshielded motor
leads
•
150m (500ft) for shielded cable.
2.2 Frequency Converter and Motor Pre-
installation Check List
•
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 same
voltage:
Mains (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 2.1 Top and Bottom Cooling Clearance
Size
a/b (mm)
Table 2.1 Minimum Airflow Clearance Requirements
To provide cooling airflow, mount the unit to a
solid flat surface or to the optional back plate
(see 2.3.3 Mounting)
Top and bottom clearance for air cooling must be
provided. Generally, 100-225mm (4-10in) is
required. See Illustration 2.1 for clearance
requirements
Improper mounting can result in over heating
and reduced performance
Derating for temperatures starting between 40°C
(104°F) and 50°C (122°F) and elevation 1000m
(3300ft) above sea level must be considered. See
the equipment Design Guide for detailed
information.
