Deenergise device and secure against being switched on again
Extreme danger!
If work is to be performed on the
devices, they must be deener-
gised. That means that all live
lines must be switched off.
Switching off the device alone is
insufficient, as certain points may
remain energised. Therefore,
switch off fuses before perform-
ing any work and – if possible – remove them.
Extreme danger!
Severe accidents can occur if the device is mistakenly
switched on again.
Immediately after deenergising, secure all switches or
fuses used for deenergising against being switched on
again.
• Lock the fuse box with a padlock.
• In case of circuit breakers which cannot be
screwed out, a strip of adhesive tape may be
applied over the actuation lever with the wording
"Do not switch, danger!".

• "Place: .............................."
• "Sign may only be removed by: ............"
must always be securely mounted immediately.
Extreme danger!
Prohibition signs must not be hung on or touch live parts.
