PROBLEM TO BE SOLVED: To solve the problem in a prior art of an inverter installation such that to drive motors, for each process of clamping, injection, measurement and projection, by each individual inverter poses problems in the installation work on site and the maintenance. SOLUTION: This inverter installation is separately constituted of a rectifier block 21 deriving DC power from an AC power supply 9, a capacitor block 22 disposing an electrolytic capacitor for filtering of the DC power, four inverter blocks 23-26 driving each motor 28-31 making the rectifier block and the capacitor block the common DC power supply, and connects these DC connection circuits with a bus bar 27. Each block is stored in a same shape case and each DC circuit terminal of the block is directly connected with the other ones in place of bus bar. |
