Information of crucial importance
• DANGER - highlights the more serious and
immediate risks able to cause severe personal
injuries and death
• WARNING - indicates risks or unsafe actions
which could cause severe personal injuries or
death.
• CAUTION - indicates risks or unsafe actions
which could cause less severe personal injuries or
material damage
• NOTE - highlights important procedures or
requirements which, in the case of non
compliance, could result in material damage
WARNING
Make sure that the specified electrical
data are not exceeded in the conditions is
which the apparatus is used. Keep the manuals in
an accessible place where they can be consulted by
all the personnel involved in the apparatus
installation, use and maintenance operations. The
utility provider’s personnel are responsible for all
issues concerning occupational safety and correct
use of the apparatus
WARNING
Always comply with the instructions in
the manual and the regulations governing
good engineering practice (GEP)! Dangerous
voltages can cause severe injuries or death.
Disconnect the supply source, then earth all live
parts before performing any work on the
apparatus. Comply with the safety regulations in
force in the place of installation

DANGER
Condensation could form if the switchgear is in
service where the humidity level is high and/or
there are considerable temperature variations.
However, the formation of condensation must be
an exception to the rule in the normal operating
conditions of indoor switchgear. Adequate
preventive measures must be taken along with the
manufacturer (e.g. installation of electric heaters)
to prevent condensation from forming and,
consequently, corrosion or other adverse effects.
The operating system of the heaters depends on
the relative design, while the specifications must
be taken from the order documents

maintenance manual for further details
about maintenance operations
WARNING
If one or more of the temperature values in
the “Real time Temp” screen exceeds 115°C,
maintenance must be planned to find out the reason
for the high temperature value and restore the circuit
to its normal operating conditions
WARNING
The switchgear has been designed for use in
normal operating conditions at up to 95%
relative humidity for 24 hours and up to 90% for one
month. Should the humidity value in the “ambient
parameters” screen exceed these values, the useful
life of the switchgear could become rapidly reduced
