2 Installation
2.1 Installation Site Check List
•
The frequency converter 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 frequency
converter
•
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
•
300 m (1000 ft) for unshielded motor
leads
•
150 m (500 ft) for shielded cable.
•
Ensure that the ingress protection rating of the
frequency converter is suitable for the installation
environment. IP55 (NEMA 12) or IP66 (NEMA 4)
enclosures may be necessary.
CAUTION
Ingress protection
IP54, IP55 and IP66 ratings can only be guaranteed if the
unit is properly closed.
•
Ensure that all cable glands and unused holes for
glands are properly sealed.
•
Ensure that the unit cover is properly closed
CAUTION
Device damage through contamination
Do not leave the frequency converter uncovered.
For “spark-free” installations according to European
Agreement concerning International Carriage of Dangerous
Goods by Inland Waterways (ADN_2011 ###), refer to VLT
®
AutomationDrive FC 300 Design Guide.
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)
Frequency converter
Motor
•
Ensure that the frequency converter output
current rating is equal to or greater than motor
full load current for peak motor performance
Motor size and frequency converter
power must match for proper overload
protection
If frequency converter rating is less than
motor, full motor output cannot be
achieved
2.3 Mechanical Installation
2.3.1 Cooling
•
To provide cooling airflow, mount the unit to a
solid flat surface or to the optional back plate
(see
•
Top and bottom clearance for air cooling must be
provided. Generally, 100-225 mm (4-10 in) is
required. See
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 1000 m
(3300 ft) above sea level must be considered. See
the equipment Design Guide for detailed
information.
