Responsibilities
Our devices are quality controlled and tested at the factory in accordance with the
standards and the regulations currently in force. Apparatus efficiency and apparatus
life depend on the compliance with the installation, commissioning and operation
instructions described in this user manual. Non respect of these instructions is likely
to invalidate any guarantee. Local requirements especially about safety and which
are in accordance with the indications given in this document, must be observed.
Schneider Electric declines any responsibility for the consequences:
■■ due to the non respect of the recommendations in this manual which make
reference to the international regulations in force.
■■ due to the non respect of the instructions by the suppliers of cables and
connection accessories during installation and fitting operations,
■■ of any possible aggressive climatic conditions (humidity, pollution, etc.) acting in
the immediate environment of the materials that are neither suitably adapted nor
protected for these effects.
This user manual does not list the locking−out procedures that must be applied. The
interventions described are carried out on de−energized equipment (in the course of
being installed) or locked out (non operational).
Particular instructions for operations and
interventions on energized equipment
When commissioning and operating the equipment under normal conditions, the
General safety instructions for electrical applications must be respected, (protective
gloves, insulating stool, etc.), in addition to standard operating instructions.
All manipulations must be completed once started.
The durations (for completing the operations mentioned) given in the maintenance
tables are purely an indication and depend on on−site conditions.
Other technical notices to be consulted

Functional interlocks
Functional mechanical interlocks
The FLUVAC circuit breaker is equipped with internal mechanical interlocks, called
”functional”, intended to avoid any kind of operating error.
It is necessary to know these interlocks in order to operate the switchgear correctly.

Identification of materials
For all orders for spare parts, it is necessary to enclose the equipment
characteristics form.
Storage conditions
The components should be stored away from dust, humidity or the sun. In order to
facilitate the search, they must be marked by the Schneider Electricreference
number.
Certain components are fragile, they should preferably be stored in their original
packaging.

Characteristics and Volumes of
SF6 gas
General characteristics
Type of Insulating Gas:
Sulphur Hexafluoride (SF6) – IEC 60376.
Each switchgear comprises a tank, filled with SF6 gas, designed as a pressurised,
sealed-unit system in accordance with the requirements of IEC.
During the expected operating life and under normal operating conditions the gas
should not need topping up.
The GWP (Global Warming Poten-tial) of the SF6 gas is 22.200.
Never pierce the pressurised tank!
Never attempt to open the tank.
Filling pressure
At 20°C the filling pressure is 0.030 MPa.
