Installation location requirements

The PQFM is suitable for indoor installation, on firm foundations, 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 3.5% 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 of cubicle versions is IP21 closed door (IP20 open door). Upon
request filters with higher protection classes can be provided. The plate versions of filter
have a protection degree IP00.
