Water cooling 
Make sure that: 
●  The cooling water supply is connected and ready for operation. 
●  The cooling water circulation (flow rate, temperature) complies with requirements. 
 
CAUTION 
 
 
Never operate the motor without the cooling water supply being switched on. Monitor 
the permissible water inlet temperatures. 
If the cooling water supply fails or the motor is operated for a short time without water 
cooling, this can cause it to overheat. This can result in material damage or destroy the 
motor completely. 
 
Brake (optional) 
Make sure that: 
●  Applying the operating voltage causes the brake to release. 
●  The brake functions (releases/engages) properly.
