Short circuit and static discharges
The device contains components that are endangered in the case of short
circuit or static discharge. A particular danger occurs because for the following
operations the device housing has to be opened during a voltage is applied:
ƒ
Connection and disconnection of the battery pack for the optional UPS
(

ƒ
Exchange of the hotplug−capable hard disks within the optional removable
rack.
Possible consequences:
ƒ
The device or parts of it are destroyed.
Protective measures:

In particular for operations on the device, for which the device can be
switched off:

– Carry out operations.
ƒ
If the housing has to be opened while a voltage is applied, be particularly
careful and carry out all operations immediately. Especially make sure that
...
– no current−carrying parts are touched.
– rotating fan blades are not touched (risk of injury!)
– no small parts that could cause a short circuit fall into the device.
ƒ
All persons operating printed−circuit boards have to provide for ESD
measures.
ƒ
Contacts of connectors may not be touched.
ƒ
Printed−circuit boards may only be touched in contact−free places and may
only be placed on suitable bases (e. g. on ESD packaging or conductive foam
plastic).
ƒ
Printed−circuit boards may only be transported and stored in ESD packaging.
