The cooling version cold plate is a particular efficient cooling alternative. The heat dissi-
pation is done via 2 contact surfaces. The first one is the mounting platform within the con-
trol cabinet or on the machine base, the other is the cold plate on the device’s back. High
requirements e.g. to surface roughness and evenness for this surface are specified, to
ensure an optimal heat flow. Already a slight damage/pollution of the surface can cause
a significant deterioration in heat dissipation to the mounting plate.
For this reason while handle the units protect the sensitive function surface to avoid dam-
age.
6.3.2
Connecting the water cooler
With water cooled devices (BM55XX-F, BM57XX-F and BM55XX-Z, BM57XX-Z) you
connect the coolant circulation before electric installation. The water cooler has on its bot-
tom side two pressfitting-transition pieces 15mm x R 1/2 ’ AG for flat washers.
h
Connect the cooling circulation to the water cooler.

In case you refer to UL 508 C: There must be a pressure-relief valve with a threshold pres-
sure of maximum 6 bar in the cooling circulation.
NOTICE!
Property damage due to overheating.
Scratches and burrs can inhibit the heat dissipation of cold plate devices.
Therefore
m
When mounting cold plate devices, ensure that the surface quality of the mounting
plate meets the specifications and ensure that the device’s rear panel/mounting
plate does not have any scratches or burrs.
