3.3.7. IP 21 Drip shield installation (D1 and D2 enclosure)
To comply with the IP 21 rating, a sep-
arate drip shield is to be installed as
explained below:
•
Remove the two front screws.
•
Insert the drip shield and replace the
screws.
•
Torque the screws to 5.6 Nm (50 in-
lbs).
3.28: Install the drip shield.
3.4. Field Installation of Options
This chapter deals with the installation of IP 00/chassis-enclosed adjustable frequency drives with
duct work cooling kits in Rittal enclosures. These kits are designed and tested to be used with
Rittal TS8 enclosures 71 in [1,800 mm] (Frame D1 and D2 only) and 79 in [2,000 mm] height, as
well as 87 in [2,200 mm] for E2 enclosures. Other enclosure heights are not supported. In addition
to the enclosure, an 8 in [200 mm] base/plinth is required.
The minimum enclosure dimension is:
•
D1 and D2 frame: Depth 19.7 in [500 mm] and width 23.6 in [600 mm].
•
E1 frame: Depth 23.6 in [600 mm] and width 31.5 in [800 mm].
The maximum depth and width are as required for the installation. When using multiple adjustable
frequency drives in one enclosure, it is recommended that each drive be mounted on its own back
panel and supported along the mid-section of the panel. These duct work kits do not support the
“in frame” mounting of the panel (see Rittal TS8 catalog for details). The duct work cooling kits
listed in the table below are suitable for use only with IP 00/chassis adjustable frequency drives
in Rittal TS8 IP 20 and UL and NEMA 1 and IP 54 and UL and NEMA 12 enclosures.
The duct work shown is for D1 and D2 enclosures. The duct work for E1 enclosures has a different
appearance, but is installed in the same way.
For the E1 enclosures, it is important to mount the plate at the absolute rear of the
Rittal enclosure due to the weight of the adjustable frequency drive.
