Rittal enclosure cooling unit
8.4.5
Re-assembling the cooling unit
Once the cleaning work is complete, the cooling unit
must be sealed and, if externally mounted, fitted back
into the mounting cut-out.
First, replace cover onto the rear panel.
It is assembled in the reverse order from dismantling
(see section 8.4.3 "Removing the cover").
Before fully replacing the cover, make sure that the PE
conductor is correctly connected to the flat-pin con-
nector on the cover (fig. 61).
Furthermore, make sure that the PE conductor is not
squashed or damaged when replacing the cover.
During installation, please observe the following tor-
ques for the cover assembly screws:
– 2 screws on the compressor console (at the bottom
of the unit): 3 Nm
– Remaining 6 / 8 screws: 2 Nm
For externally mounted units, re-fit the cooling unit into
the mounting cut-out (see section 5.3.4 "External
mounting of the cooling unit").
For internally mounted units, re-fit the louvred grille
onto the cooling unit (see section 5.3.5 "Internal
mounting of the cooling unit").
Make the electrical connection for the cooling unit.
Warning!
If the PE conductor is not connected or
has been incorrectly connected, there is
a danger to life from electric shock.
