When operating electrical devices, certain parts of these devices are inevitably
under hazardous voltage.
Improper handling of these devices may therefore result in loss of life, severe
personal injury or substantial material damage.
When servicing these devices, you should therefore observe all notices pro-
vided in this Section and attached to the product itself.
– This device may only be serviced by accordingly qualified personnel.
– Before starting any maintenance and service work, disconnect the device
– Use only spare parts approved by the manufacturer.
– Strictly observe the prescribed maintenance intervals, as well as the in-
structions for repair and replacement.
The module contains electrostatically sensitive devices.
Electrostatically discharge your own body before touching the module. To do
so, touch an earthed, conductive object (e.g. blank cubicle parts, socket protec-
tion contact) immediately before starting work on the module.
