16 Rittal enclosure cooling unit
 Loosen the four threaded bolts in the corners of the
cover which connect the cover to the chassis.
 Carefully pull the cover forwards (approx. 5 cm) from
the chassis.
The PE conductor connection between the cover and
the chassis is located on the right-hand side, approx-
imately halfway up.


Pull the flat-pin connector of the PE conductor off in-
wards, preferable on the chassis.
 Remove the cover completely from the chassis, and
place or lay it down somewhere safe.
There is a clip prefitted to the top edge of the chassis
on the front. This clip will later prevent the chassis from
falling out of the mounting cut-out before it is properly
secured with the threaded bolt.


Lift up the chassis, preferably with a lifting eye using
suitable lifting gear, and insert it into the mounting cut-
out in the door or side panel of the enclosure from the
inside with the edge fold at the bottom of the chassis.
 If transportation by crane is not possible, lift the chas-
sis into the mounting cut-out in the same way using
the handle.

 Push the chassis into the mounting cut-out at the top
until the clip behind the cut-out latches home.
Caution!
The cooling unit will only be stable as
long as the cover and chassis are con-
nected. For this reason, be sure to brace
the chassis, in particular, to prevent it
from falling over before removing the
cover.
