Important notes on rack assembly
Higher operating temperature
If installed in a closed unit or a multi-
unit rack, the ambient operating temperature may be
greater than the room temperature. Install the device in an environment recommended
by the manufacturer, see notes under "Climatic and mechanical environmental conditions
(Page 148)"
Reduced air flow
When installing the device in a rack, ensure that the air flow required for safe operation of
the device is guaranteed, see instructions under "Climatic and mechanical environmental
conditions (Page 148)".
Mechanical load
Mounting of the equipment in the rack should be such that a hazardous condition is not
caused due to an uneven mechanical load, see notes under "Climatic and mechanical
environmental conditions (Page 148)"
Circuit overload
When connecting the device, observe the information on the power supply unit on the
information label on the rear of the device.
Reliable grounding
Ensure that the equipment installed in the rack is safely grounded, see the notes under
"Connection of equipotential bonding line (Page 58)"
Danger to life when the control cabinet is open
Electrocution risk when control cabinet is open
When you open the control cabinet, there may be a dangerous voltage at certain areas or
components.
Touching these areas or components can cause death or serious physical injury.
• Disconnect the control cabinet from the power supply before opening it.
