Ignoring the following safety messages can result in death or serious injury or physical
damage.
DANGER!
Only qualied electricians may install, commission, work or operate this device.
All national standards – if applicable – must be followed.
DANGER!
The terminal block for connection to the current transformers is not a shorting block.
Therefore always short-circuit current transformers before loosening the terminals.
Ignoring this can result in dangerous voltages at the open contacts (up to dozens of
kilovolts depending on the CT type).
DANGER!
Even when the auxiliary voltage is switched o, it is likely that there are still hazardous
voltages at the component connections.
Upon opening the device, it is likely that some parts with high voltages become
accessible. Touching these is dangerous to life.
The device must be carefully grounded. See ╚═▷ “3.3.1 Grounding”.
