3.3 Installation
Checking the shipping and handling indicators prior to commissioning
It is essential to check the shipping and handling indicators prior to commissioning the
converter.
Figure 3-5
The tilt indicator provides immediate visible evidence of whether the cabinet units have been
handled and stored upright. Blue-colored quartz sand begins to flow into the arrow-shaped
indicator area. The tilt indicator has tripped when the blue color extends beyond the middle
line of the arrowhead.
Figure 3-6
The shock indicator shows if an acceleration has exceeded 98.1 m/s
the direction of acceleration. The black color of the arrows indicates that an impermissible
shock load has occurred in the direction of the arrow.
Inform Technical Support (hotline)
Commissioning must not be carried out, if an indicator has tripped. Please contact
Technical Support immediately.
If commissioning is carried out without prior inspection of the indicators, safe operation of
the converter cannot be guaranteed. This can result in death, serious personal injury or
material damage.
