Troubleshooting, Repair, Cleaning

The user is not authorized to repair the device when it
is defective. This is because the device contains
special electronic components that may only be
handled by the manufacturer in compliance with the
regulations for electrostatic sensitive devices (ESD).
Furthermore, hazardous voltages can lead to lethal
injuries when the work is performed improperly.
If you suspect that the device has a defect, Siemens
recommends to send the entire device back to the
manufacturer. If possible, use the original transport
packaging or an equivalent packaging.
Cleaning: Switch off the device. Wiped the device with
a clean, dry and soft cloth. Do not use solvents.

Storage and Transport

Storage
Store the device in a dry and clean location. The
temperature range for storing the device or any of its
replacement modules is -40 °C to +70 °C (-40 °F to
+158 °F).
The relative air humidity must not lead to condensation
or ice formation.
To avoid premature aging of the electrolytic capacitors,
store the device within the recommended temperature
range of +10 °C to +35 °C (+50 °F to +95 °F).
If the device is stored for an extended period of time,
Siemens recommend to connect the device to the
supply voltage for 1 or 2 days once a year to reform the
electrolytic capacitors in the device. This procedure
should also be carried out before operating the device.
In this context, pay attention to the commissioning
notes in Chapter 10.
