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.COOLING

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.ELECTRICAL 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.ACCESS TO THE FILTER

The inside of the filter can only be accessed by qualified electricians and only with no voltage.
