5 Mechanical design and installation
5.1
What this chapter contains
This chapter gives the information required for the mechanical design and installation
of the filter system.
In case you have a problem, please notify it to our service support mail box:
jumet.services@be.abb.com.
5.2
Installation location requirements
The PQFS is suitable for indoor wall-mount installation, in a well-ventilated area without
dust and excessive aggressive gases where the ambient operating conditions do not
exceed the following values:
Altitude
Minimum temperature
Maximum temperature
Maximum average
temperature (over 24 h)
Relative humidity
Contamination levels
(IEC 60721-3-3)
Remarks:
(a)
At sites over 1000m (3300ft) above sea level, the maximum output current must be derated
by 1% every additional 100m (330ft). The derating factor must be entered at commissioning.
(b)
Above 40°C (104°F), the maximum output current must be derated by 2% every additional
1°C (1.8°F) up to 50°C (122°F) maximum limit. The derating factor must be entered at
commissioning.
(c)
Locations with normal levels of contaminants, experienced in urban areas with industrial
activities scattered over the whole area, or with heavy traffic.
(d)
Locations without special precautions to minimize the presence of sand or dust, but not
situated in proximity to sand or dust sources.
The filter installation must be indoor and it should be taken into account that the
standard protection class is IP30.
WARNING: Conductive dust may cause damage to this equipment. Ensure that the
filter is installed in a room where no conductive dust is present.
