Figure 3-4 Power options available for Unidrive SPM
All Unidrive SPM Solutions Modules are color-coded in order to make identification easy. The following table shows the color-code key and gives 
further details on their function.

A separate input line reactor of at least the value shown in 
Table 6-2 and Table 6-3 on page 68 must be used with the 
rectifiers. Failure to provide sufficient reactance could 
damage or reduce the service life of the rectifier or inverter.
Power down the drive before installing / removing the 
Solutions Module. Failure to do so may result in damage to 
the product.
