2 Installation
2.1 Installation Site Checklist
•
The adjustable frequency 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 adjustable
frequency drive
•
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
•
1,000 ft [300 m] for unshielded motor
leads
•
500 ft [150 m] for shielded cable.
•
Ensure that the ingress protection rating of the
adjustable frequency drive 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 connectors and unused
holes for connectors are properly sealed.
•
Ensure that the unit cover is properly closed
CAUTION
Device damage through contamination
Do not leave the adjustable frequency drive 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 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
Adjustable frequency drive
Motor
•
Ensure that the adjustable frequency drive output
current rating is equal to or greater than motor
full load current for peak motor performance.
Motor size and adjustable frequency
drive power must match for proper
overload protection
If adjustable frequency drive 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 backplate (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 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.
