Warning : a misalignment of the coupling device makes stress and load on 
the motor shaft depending the rigidity of the installation. 
The variations of the temperature makes stress and load due to the 
dilatation. These loads (axials and radiale) do not exceed the load written 
(§ 3.5). 
Warning : The misalignment of the coupling device makes vibration who can 
realize a destruction of the motor shaft. 
We cannot be held responsible for wear on the drive shaft resulting from 
excessive strain. 
 
4.3.  Electrical connections 
Danger: Check that the power to the electrical cabinet is off prior to making 
any connections. 
Caution: The wiring must comply with the drive commissioning manual and 
with recommended cables. 
Danger: The motor must be earthed by connecting to an unpainted section 
of the motor.
