Modified Cover Material
220 - 240V / 50Hz Compressors
In the latest standard “Safety of household and similar electrical appliances, IEC60335-1, Edition 4” the flammability safety demands have been changed.
This new standard becomes e ective in EU (EN 60335-1) from October 2005 for light commercial appliances and from October 2006 for household appliances. Other countries can have di erent schedules.
Danfoss will change the cover material according to the table to comply with this new standard. The cover code nos. will not be changed.
Our existing Capron 8202 covers would normally (e .g. with PTC in a household appliance) comply with this new standard. Generally, this material is acceptable if electrical connections (≥0.2 Amps) under the cover are placed ≥ 3 mm from the cover. However, if e.g. a special wiring of a HST start equipment (relay and not PTC) is used, the distance can be less than 3 mm.
Therefore, Danfoss will change the material of the cover in connection with our TL, NL, and FR compressors for 220-240V/50Hz operation from Capron 8202 to Ultramid B3S and in connection with our PL, TF, NF, FF, and SC compressors for 220-240V/50Hz operation to Noryl SE1.
The change of material will take place by the end of September 2005atthelatest.
In case of the standard Ultramid cover (code no. 103N2010) for TL, NL, and FR it is permissible that an inside electrical connection touches the cover. However, there has to be a certain free space outside thecover(ø20x50mmtoelectrical connections). If this is not the case, the “disturbing” external part has tobeofnon-flammablematerialor it has to be able to pass the needle flame test.
