WARNING! Operating the equipment incorrectly can cause serious injury and
damage. All activities described in the service instructions must only be carried
out by trained personnel. Read the „Safety rules" chapter in the power source
operating instructions.
WARNING! An electric shock can be fatal. Before opening the device
- Turn the mains switch to the „O" position
- Disconnect the device from the mains
- Put up an easy-to-understand warning sign to stop anybody inadvertently
switching it back on again
- Using a suitable measuring instrument, check to make sure that electri-
cally charged components (e.g. capacitors) have been discharged
WARNING! An electric shock can be fatal. If the device needs to be switched
on briefly for testing while the housing is open,
- Do not touch the parts inside the housing
- Only touch using suitable measuring or test probes
CAUTION!! Failure to connect an appropriate earth lead may result in serious
injury or damage. The housing screws provide a suitable PE conductor
connection for earthing (grounding) the housing and must NOT be replaced
by any other screws which do not provide a reliable PE conductor connection.
