Risk of injury by electrical accident
■
If the device has to be opened for setting or service work:
w
First disconnect the device from all voltage sources.
■
If the opened device must remain under voltage during work:
w
Have the work done by skilled persons familiar with potential risks. If it is nec‐
essary to remove or open internal components, live parts could be exposed.
■
If any liquid has penetrated electrical device components:
w
Put the device out of operation and interrupt the power voltage at an external
point (e.g. disconnect the power cable). Then contact service technicians of
the manufacturer or correspondingly trained skilled persons to have the
device repaired.
■
If safe operation of the device is no longer possible:
w
Put the device out of operation and secure against unauthorized start-up.
■
Do not interrupt the protective conductor connections inside or outside the device.
CAUTION
Device damage through short circuit on the device
The internal electronics can be damaged when signal connections are established and
