System expansions
Install only system expansions that are intended for this device. Installing other expansions can
damage the system or violate the safety provisions and regulations for radio interference
suppression. You can obtain information on system expansions suitable for installation from the
technical customer service or from the sales office responsible for your area.
NOTICE
Warranty on system expansions
Any device defects caused by installing or replacing system expansions will void the warranty.
NOTICE
Electrostatic sensitive devices
The device contains electrostatic sensitive devices. Electrostatic sensitive modules can be
damaged or destroyed by voltages. These voltages are well below the limits of human
perception. Such voltages occur if you touch a component or the electrical connectors of a
module without first discharging the static from your body. Module damage caused by
overvoltage is often not detected immediately. The damage only becomes apparent after an
extended period of operation.
Measures for protecting against discharge of static electricity:
• Always discharge your body's static electricity before working on modules. Static electricity
can be discharged by touching a grounded object, for example.
• Discharge any devices and tools used.
• Only hold modules by the edge.
• Do not touch connector pins or printed conductors.
