Mechanical installationThe encapsulation of the filters have an IP 20 rating.The modules can be mounted side by side with 60mm(2,36 inches) clearance.To other components and to the cabinet walls keep ahorizontal clearance of at least 70mm (2,76 inches)and a vertical clearance of at least 150mm (5,91 in-ches).Only vertical installation is allowed (mains terminal atbottom).For versions with bus bars (frame size E– H) it is necessary to mount the addedcovers to the connectors in order to ach-ieve the protection type IP 20.VentilationThe filters are cooled by means of air circulation. Con-sequently, the air needs to be able to move freelyabove and below the filter module. The efficiency ofthe filter modules is greater than 0.98. When installinga filter module in a panel or another enclosure, ensurethere is sufficient airflow though the enclosure to limitheat rise in the enclosure.AHF 0xx, 380 – 415VMax.

Ensuresufficient countermeasures, e.g. separatecooling air, mounting of air filters, period-ical cleaning.Power wiringStandard connectionSupply voltage must be connected to the terminalsX1.1, X1.2 and X1.3. The frequency converter supplyterminals L1, L2 and L3 must be connected to the filtermodule terminals X2.1, X2.2 and X2.3.AHF 005/010MG.80.B5.02 - VLT ® is a registered Danfoss trademark 13Installation
