3. SAFETY
CAUTION !!! The CleanWave
®
filter exhibits potentially lethal voltages.
Like any electrical equipment, the installation and the use of the CleanWave
®
require some basic
precautions.
3.1. INTEGRATION IN HOUSING
The IP00 filters are intended to be integrated by the customer. They must be integrated by qualified
electricians in a housing or electrical cabinet guaranteeing the safety of the users according to
regulations, standards and rules of application in the corresponding country (Protection rating must
be at least IP20).
The IP21 version of the CleanWave
filter is already integrated in its housing and represents no
danger for people. It is forbidden to dismount the enclosure while the filter is energised.
3.2. C
OOLING
Though well the CleanWave
filter has an excellent efficiency, its losses must be dissipated. The
maximum total losses in standard conditions are given in table 4.
In the case of the IP21 version, the integrator must ensure that the ventilation grids on the front
and rear sides of the filter are not obstructed. A minimum distance of 100mm must be free on both
sides of the housing. The ambient temperature should not exceed the maximum tolerated value
(as a standard, 50°C without de-rating).
In the case of the IP00 version, it is the integrator 's responsibility to ensure a correct dissipation of
the losses given in table 4.
3.3. E
LECTRICAL CONNECTIONS
The cabling of the CleanWave
®
filter must be done with no voltage and by a qualified technician.
It is critical to respect the instructions given below as regards minimum wiring sections and
electrical protections. Some local regulations, particularities of the electrical installation or specific
rules may however impose the use of bigger sections.
The earth terminal of the filter must be properly connected to the earth of the installation, in respect
of the minimum recommended sections.
3.4. A
CCESS TO THE FILTER
The inside of the filter can only be accessed by qualified electricians and only with no voltage.
