3.2.5 Safety Requirements of Mechanical Installation
Pay attention to the requirements that apply to integration and the field mounting kit. Observe the information in the list to avoid
serious injury or equipment damage, especially when installing large units.
The adjustable frequency drive is cooled by air circulation.
To protect the unit from overheating, it must be ensured that the ambient temperature
does not exceed the maximum temperature stated for the
adjustable frequency drive
, and that the 24-hour average temperature
is not exceeded
. Locate the maximum temperature and 24-hour average in the
paragraph
Derating for Ambient Temperature
.
If the ambient temperature is in the range of 113°–131°F [45
°
C–55
°
], derating of the adjustable frequency drive will become relevant, see
Derating for
Ambient Temperature
.
The service life of the adjustable frequency drive is reduced if derating for ambient temperature is not taken into account.
3.2.6 Field Mounting
For field mounting the IP 21/IP 4X top/,TYPE 1 kits or IP 54/55 units are recommended.
3.2.7 Panel Through Mounting
A Panel Through Mount Kit is available for adjustable frequency drive series VLT HVAC Drive, VLT Aqua Drive and .
In order to increase heatsink cooling and reduce panel depth, the adjustable frequency drive may be mounted in a through panel. Furthermore, the built-
in fan can then be removed.
The kit is available for enclosures A5 through C2.
NOTE!
This kit cannot be used with cast front covers. No cover or IP21 plastic cover must be used instead.
Information on ordering numbers is found in the
Design Guide
, section
Ordering Numbers.
More detailed information is available in the
Panel Through Mount Kit instruction, MI.33.H1.YY,
