How to Install
enclosure that provides a greater degree of protection
against weather and hosed water.
The minimum enclosure depth is 500 mm (600 mm for
enclosure type E2) and the kit is designed for a 600 mm
(800 mm for enclosure type E2) wide enclosure. Other
enclosure widths are possible, however additional Rittal
hardware is required. The maximum depth and width are
as required by the installation.
NOTICE
The current rating of frequency converters in enclosure
types D3 and D4 are de-rated by 3%, when adding the
NEMA 3R kit. Frequency converters in enclosure type E2
require no derating.
NOTICE
A doorfan(s) is required on the enclosure to remove the
heat losses not contained in the backchannel of the
frequency converter and any additional losses generated
from other components installed inside the enclosure.
The total required airflow must be calculated so that the
appropriate fans can be selected. Some enclosure
manufacturers offer software for performing the
calculations (i.e. Rittal Therm software). If the frequency
converter is the only heat generating component in the
enclosure, the minimum airflow required at an ambient
temperature of 45 °C for the D3 and D4 frequency
converters is 391 m 3 /h (230 cfm). The minimum airflow
required at an ambient temperature of 45 °C for the E2
frequency converter is 782 m

3.3.6 Outside Installation/NEMA 3R Kit of
Industrial Enclosures
The kits are available for the frame sizes D3, D4 and E2.
These kits are designed and tested to be used with IP00/
Chassis frequency converters in welded box construction
enclosures with an environmental rating of NEMA-3R or
NEMA-4. The NEMA-3R enclosure is a dust tight, rain tight,
ice resistant, outdoor enclosure. The NEMA-4 enclosure is a
dust tight and water tight enclosure.
This kit has been tested and complies with UL environ-
mental rating Type-3R.

Note: The current rating of D3 and D4 frame frequency
converters are de-rated by 3% when installed in a NEMA-
3R enclosure. E2 frame frequency converters require no de-
rating when installed in a NEMA-3R enclosure.

3.3.9 Installation on Pedestal

This section describes the installation of a pedestal unit
available for the frequency converters enclosure types D1
and D2. This is a 200 mm high pedestal that allows these
enclosure types to be floor mounted. The front of the
pedestal has openings for input air to the power
components.
The frequency converter gland plate must be installed to
provide adequate cooling air to the control components of
