Abstract

Abstract PURPOSE:To reduce the outer package leakage current by insulating electric circuit units and an outer package body with insulating members and connecting the electric circuit units to the ground potential point of an external power source. CONSTITUTION:Insulating members 12-15 are inserted between electric circuit units 1-4 and a frame 5, and metallic fitting plates 1A-4A of the electric circuit units 1-4 are connected to the grounding terminal 9 of a distribution board 8 serving as an external power source with the third grounding cable 16. The grounding terminal of the distribution board 8 is the ground potential point, the leakage current flowing via stray capacities C1-C4 flows to the ground via the third grounding cable 16 and does not flow to the frame 5 serving as an outer package body. Even when high-frequency inverters are used as the electric circuit units 1-4, the indication of an ammeter 11 between the grounding terminal E and the frame 5 becomes the specified value or below, and the outer package leakage current can be reduced.
