9.3 Mounting notes
The coolant inlet and outlet is carried out via smooth stainless steel tubes Ø8 x 1 (Ø10x1 for DSC1-
135) on the B-side of the motors.
A suitable connection to the external cooling circuit can be established, for example, by using John
Guest SM 040808 S quick connectors (Ø8 to Ø8). Any other connection that is approved for the
connection to smooth stainless steel pipe ends and can withstand operating and test conditions can
also be used.
Cooling circuit connection:
No tensile, compressive or torsional loads may be applied to the motor connec-
tions from coolant lines.
The connection may only be carried out by qualified personnel. Thereby, the motor
must be disconnected from current and voltage.
When connecting or disconnecting the cooling lines, make sure that no coolant en-
ters the motor terminal box.
Sealing test according to EN 50178:
The sealing of the cooling system must be checked before commissioning by
pressing the coolant (water). The test pressure must be twice the operating pres-
sure (minimum test pressure 1 bar). The coolant used does not need to be brought
to operating temperature here. The pressure must be maintained until the sealing
has been checked at all points (minimum test time 10 minutes)
9.4 Electric connection
The power connection with the water-cooled motors is executed in accordance with the dimension-
al drawings in the technical documentation.
