6.1 Safety in Liquid-cooling
POISONOUS COOLANTS
Glycols and inhibitors are poisonous. If touched or consumed, they can cause injury.
-
Prevent the coolant from getting into the eyes. Do not drink the coolant.
HOT COOLANT
Hot coolant can cause burns.
-
Avoid contact with the hot coolant.
PRESSURIZED COOLING SYSTEM
Sudden release of pressure from the cooling system can cause injury.
-
Be careful when operating the cooling system.
INSUFFICIENT COOLING CAPACITY
Insufficient cooling can cause the product to become too hot and thus become damaged.
-
To make sure that the cooling capacity of the cooling system stays sufficient, make sure that the cooling system is vented
and that the coolant circulates properly.
DAMAGE TO COOLING SYSTEM
If the coolant circulation is stopped too soon, high temperature components can cause rapid local increase in the coolant tem-
perature, which can damage the cooling system.
-
Do not stop the cooling system when stopping the drive. Keep the coolant circulation flowing for 2 min after the drive has
been stopped.
6.2 The Operating Principle of the Cooling Module
The operating principle of the cooling module is to transfer heat from the drive circuit into the external circuit.
The heat load is transferred from the drive to the drive circuit. The heat load is then conducted inside the plate heat exchanger from
the drive circuit to the external circuit. The external circuit removes the heat load. The removal can be done, for example, with an
external condenser, which is a part of your existing cooling system.
If the system has the option +SCXX (no heat exchanger), an external heat exhanger must be used instead of the internal heat ex-
changer of the cooling module.
