3.4.5 Outside Installation/NEMA 3R Kit for
Rittal Enclosures
176FT261.10
Figure 3.41 Rittal Enclosure Size E2
This section is for the installation of NEMA 3R kits available
for the adjustable frequency drive enclosure size E2. These
kits are designed and tested to be used with IP00/Chassis
versions of these enclosure sizes in Rittal TS8 NEMA 3R or
NEMA 4 enclosures. The NEMA 3R enclosure is an outdoor
enclosure that provides a degree of protection against rain
and ice. The NEMA 4 enclosure is an outdoor enclosure
that provides a greater degree of protection against
weather and hosed water.
The minimum enclosure depth is 500 mm (19.7 in) (600
mm (23.6 in) for enclosure size E2) and the kit is designed
for a 600 mm (23.6 in) (800 mm (31.5 in) for enclosure size
E2) wide enclosure. Other enclosure widths are possible;
however, extra Rittal hardware is required. The maximum
depth and width are as required for the installation.
NOTICE!
Adjustable frequency drives in enclosure type E2 require
no derating.
NOTICE!
Install a door fan on the enclosure to remove the heat
losses not contained in the backchannel of the
adjustable frequency drive and any additional losses
generated from other components installed inside the
enclosure. Calculate the total required airflow to select
the appropriate fans. Some enclosure manufacturers
offer software for performing the calculations (Rittal
Therm software). If the adjustable frequency drive is the
only heat-generating component in the enclosure, the
minimum airflow required at an ambient temperature of
45
°
C (113 °F) for the E2 adjustable frequency drive is
782 m
3
/h (460 cfm).

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.
