1. CAUTION
When MV equipment is operating, certain components
are live, other parts may be in movement and some
may reach high temperatures.
Therefore, the use of this equipment poses electrical,
mechanical and thermal risks.
Consequently, the equipment to which the present
manual refers complies with the requirements
of section 11.2 of Standard IEC 62271-1. It must
therefore only be operated by appropriately qualified
and supervised personnel, in accordance with the
requirements of standard EN 50110-1 on the safety
of electrical installations and standard EN 50110-2
on activities in or near electrical installations.
Personnel must be fully familiar with the instructions
and warnings contained in this manual and in other
recommendations of a more general nature which
are applicable to the situation according to current
legislation.
The above must be carefully observed, as the
correct and safe operation of this equipment
depends not only on its design but also on general
circumstances which are in general beyond the
control and responsibility of the manufacturer.
More specifically:
The manufacturer guarantees this product against
any defect in materials and operation during the
contractual period. In the event that defects are

Warranty
Mortal danger due to high voltage. Before performing
assembly or maintenance work, the system must be
isolated from high voltage, and earthed.
Mortal danger due to supply voltage. Before performing
assembly or maintenance work, the system must be
isolated from the supply voltage.
Risk of injury from movable parts in mechanical drives.
Before performing maintenance work,
After the removal of covers from a switchgear,
operator safety regarding internal arcs may be reduced
unless the switchgear is isolated from the power
supply. Optimum operator safety is only ensured if
the switchgear is completely isolated from the power
supply and earthed for assembly work.
Isolate the system from the supply voltage
Release the circuit-breaker’s energy storing device by
OFF- ON - OFF operation and in case of a make-proof
earthing switch, by the appropriate ON- operation.
