6 – Fastmig™ Kms 400 mVU / 0647 © Kemppi oy60ºmax. 15º2. INSTALLATION2.1. SITING ThE mAChINESite the machine on a stationary, horizontal, dry base in a position that does NOT allowdust, dirt or metal particles to enter the machines cooling air flow.2.2. CONNECTION TO ThE mAINS SuPPLyFastMig™ power sources are delivered equipped with 5 m mains cable without plug.If local electricity regulations of operating country are stating otherwise, the mains cable shouldbe replaced in conformity with the local regulations.Connection of the mains cable, mounting and change of the plug should only be carried out by acompetent electrician.Remove the machine’s right side plate to enable the mounting of a mains cable.KMS 400 MVU power source can be connected to the mains supply of 230 V 3~ or 400 V 3~.Power source recognizes the mains voltage automatically. For fuse and cable sizes, see the technicaldata in the end of this document.If changing the mains cable take into consideration the following:The cable is entered into the machine through the inlet ring on the rear panel of the machine andfastened with a cable clamp (05). The phase conductors of the cable are coupled to connectors L1,L2 and L3. The earth protection coloured green-yellow is coupled to connector.If you are using 5-lead cable, do not connect neutral conductor.rain water– Preferably site the machine somewhat higher abovethe floor level.– Ensure that the front as well as the rear of themachine there is at least 20 cm free distance toallow good circulation of the cooling air throughthe machine.– Protect the machine against heavy rain and in hotcircumstances against direct sunshine. Ensure thefree circulation of the cooling air.Degree of protection of machine IP23S allows atits maximum the water spray coming in 60º angleto hit machine’s outer covering.See to that the machine is positioned away from the lineof particle spray, created by grinding tools etc.
