Automatic COSYS PFC system
Automatic COSYS PFC system
- Ref. : 539931A
INSTALLATION
Failure to follow the installation instructions contained in this manual may compromise the
operation and reliability of the PFC system.
Recommendations relating to installation conditions
Recommended operating temperature: between 15°C
and 35°C.
Relative humidity without condensation: 90% max.
Maximum operating altitude: 2,000 m
Take all necessary precautions to prevent splashes of
water, paint or other fluids.
The enclosure conforms to protection rating IP20.
It is essential to ensure that there is a clearance of 50 cm
above the PFC system to allow adequate ventilation.
Connecting the input cables
The power is supplied to the terminals provided for this
purpose.
The power, control and measurement cables should be
connected in accordance with the standards in force
and good practice.
The cable bushing plate should be refitted after the cable
gland or other cable passage system has been fitted.
Failure to follow this instruction may seriously
compromise the ventilation efficiency, reduce the
cabinet's level of protection and cause the formation of
hazardous material or objects.
Upstream protection and connection cross section
The selection and co-ordination of the protection
devices upstream of the PFC system depend on the
nominal current and cable fitting conditions.
The protection devices upstream of the PFC system
must conform to the safety standards in force.
The cross section of the should be adapted to the
power of the automatic PFC system. Cables should be
selected according to the current values shown in the
table below, which should be increased by a coefficient
of 1.43 in accordance with CEI 60831-1.
