7.7 External heat sink kit
The SK 5xxEseries with ColdPlate technology (SK 5xxE-…-CP) can be
extended with the external heat sink kit.
In this construction, the heat sink is outside of the control cabinet and
therefore does not need a “suitable cooling surface”. The device is cooled by
the external air.
This results in the following operating modes:
Option type Size Power [kW] Operating mode
SK TH1-1
Mat. No. 275999050
S1 0.25 – 0.75 S1
SK TH1-2
Mat. No. 275999060
S2 1.1 – 1.5 S1
The external heat sink kit contains the following:
• Heat sink
• Seal
• Heat-conducting paste
• 4 screws, also for sizes 3 + 4
Please only use the parts supplied, in order to ensure safe
operation.
