19" rack mounting of the PS598-1 power supply unit 
Notes on 19" rack mounting of the PS598-1 power supply unit 
The PS598-1 was developed specifically for use with the SCALANCE XR528-6M and 
SCALANCE XR552-12M devices. This power supply unit can be mounted directly above or 
below a SCALANCE XR-500 since the ventilation slits are on the sides of both the basic 
device and the power supply unit. 
 
Risk of injury if subjected to irregular mechanical strain 
The device must be mounted in the rack so that even if there is irregular mechanical strain, 
no dangerous situation can result.
