iC7 Series Cooling Modules
Operating Guide
The default reference temperature of the coolant is +45 °C (113 °F). If the temperature increases above the reference, the 3-way
valve starts to increase the flow through the heat exchanger and directs less liquid through the bypass. Keeping the temperature as
high as possible in the drive circuit lowers the risk of condensation inside the drive cabinet.
See 6.17.1 Filling the Cooling System by Progressive Circulation
information.

6.4 Components of the External Circuit
The external circuit transfers the heat load from the heat exchanger to a customer-specific object. The upper pipe is the outlet, and
the lower pipe is the inlet.
LACK OF SUPERVISION IN THE EXTERNAL CIRCUIT
The cooling module does not have a supervision system for the external circuit. If there is no supervision in the external circuit, it
is hard to determine the reason for a possible alarm or fault in the cooling module.
-
Use suitable devices to control and supervise leaks, flow, and temperature in the piping of the external circuit.
-
Use, for example, a leakage sensor, a flow meter, and a temperature sensor.
VIBRATION HAZARD
Vibration shortens the mean time between failure (MTBF) of the cooling module.
-
Prevent all forces or vibrations from entering the cooling module through the pipe connections of the external circuit or
through the fixing points of the cooling module.
