Hazard:
Once the communication server is connected to the mains, there are haz-
ardous voltages inside the housing. Always observe the following points
before removing the housing cover:
– Disconnect the communication server from the power supply.
– Wait at least one minute so the charged capacitors have time to dis-
charge.

Components, interface cards or system modules can be damaged by
electrical voltage.
Always disconnect the communication server from the power supply
before removing the housing cover.
Warning
Components can be damaged by electrostatic discharge when touched.
Always touch the earthed metal case of the communication server before
carrying out work inside the housing. This also applies to interface cards
and system modules that are no longer packed inside the ESD protective
wrapping.
