Suitable connectors are required for connecting the hoses.
Note
Keep the pressure loss for motors with precision and main cooler low
Apply measures to keep the pressure loss low:
• Connect the precision and main coolers in parallel using the cooling connection adapter
immediately before the cooler connections.
• Use cooling lines with the largest possible cross-section for coolant intake and return.
• Avoid reducing cross-sections as a result of unnecessary coupling locations.
The optional cooling connection adapter that can be ordered can be connected via a 1/4"
pipe thread (DIN 2999) either axially or radially (on the outside).
Note
Cooling principle
Every cooler has an inlet and a return. As far as cooling is concerned, it does not make any
difference in which direction the coolant flows through the cooling circuit. Which connection
point is used as the inlet and which as the return can be freely selected.
In a series connection, the coolant must flow through the precision cooler first and then the main
cooler. Otherwise, the coolant already warmed up in the main cooler would enter the precision
cooler and have a negative impact on the cooling effect.
NOTICE
Destruction of the motor
Most of the motors have a permanently mounted cooling connection plate. If you remove the
cooling connection plate, the motor could be destroyed.
• Do not remove the cooling connection plate.
Note
Locking plate for the coolant connection
It is only permissible to remove the locking plate for the coolant connection for 1FW6050 and
1FW6060 motors for service purposes, and this must be done by a Siemens Service Center
employee.
