Installation

8.1 Top panel cooling unit

085 408 025b
CAUTION:
If there is excessive condensate during normal operation check the sealings of the switch
cabinet.
We recommend that you install a door contact switch to switch off the cooling unit, when
the door of the switch cabinet is opened, in order to prevent excessive condensate (op-
tion).
• The installation place for the switch cabinet must be selected such that proper ventila-
tion of the cooling unit is ensured.
• The single units or the units and the wall must be at a distance of 200 mm at least.
• Air circulation in the switch cabinet must not be impeded by built-in parts.
• The unit cover needs not be removed for installation of the cooling unit.
• The site of installation must be protected against contamination.
CAUTION: Chips may damage the switch cabinet.
Prevent chips from entering the switch cabinet, e.g. place a cover underneath.
CAUTION: Danger due to improper condensate drainage.
Install the top panel cooling unit either horizontally or such that the condensate drainage is
not situated at the bottom.
The condensate drainage hose must be inclined downward without showing a bend. The
max. length is 2 m.
The end of the hose must not dip into water. A return flow must be prevented; vent the
hose, if necessary.
Regularly check during operation whether condensate is properly drained.
1) Make cutout(s) and drillings for the cooling unit, if not already provided in the switch
cabinet (see drawing on accompanying sheet).
2) Either glue the self-adhesive surface sealing to the switch cabinet or place the profile
sealing strip into the openings. The strip doubles as edge protection.
Hint:
If necessary, reinforce the installation area at the switch cabinet to achieve proper sealing
between cooling unit and switch cabinet.
3) Place the cooling unit onto the top panel of the switch cabinet and adjust it to suit the
openings; thread power and control cables through the air inlet opening into the switch
cabinet.
Hint:
The cooling unit can be lifted using a lifting device (e.g. crane). For this purpose, screw in
two (in case of DTD 5501 four) lifting eyes after having removed the cover provided at the
top.
