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
(
¶ 55).
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:
ƒ In particular for operations on the device, for which the device can be
switched off:
– Shut down the IPC and switch it off.
– Disconnect the mains supply plug.
– Open the housing and, if available, immediately disconnect the battery
pack (
¶ 55).
– 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.
