Coolant connectors
The coolant pipe inlet and outlet connectors are located at the bottom front of the IGBT
supply module. The connectors are for 16/13 millimeter PA (polyamide) pipe.
WARNING!
For a reliable connection, the end of the pipe entering the connector must be
completely intact for a length of at least 5 cm (2 in). Make sure the pipe is perfectly
round where it enters the connector, and not deformed eg. by any bends nearby.
The piping must not exert any tension or torque on the connector.
Type designation label(s)
Each IGBT supply unit has a type designation label attached onto the inside of the cubicle
door. The type designation label includes the ratings, appropriate markings, a type
designation and a serial number of the unit. Example label is shown below.
Quote the complete type designation and serial number when contacting technical support.
