PURPOSE:To ensure the safety in the loading/unloading of a high-electric unit, by a construction wherein a high-voltage or high-current portion in an electrically conductive state cannot be touched and the high-electric unit cannot be pulled out unless the connection of a connector disposed on the end surface on the side of pulling out from an electric. equipment is cut. CONSTITUTION:A high electric portion is on the primary circuit side of a DC power unit PSU 13, and the whole PSU is loaded on an L-shaped chassis 21 raised at the pulling out side thereof. This raised portion closes the opening of a body housing. An electric power input connector 22 is disposed on the outer surface of the raised portion of the chassis 21. A lead wire 23 is made as short in length as the connector 22 can be connected to a connector 22a only in the condition that the PSU 13 is stored in the body housing 20. Therefore, an operator must necessarily cut the connection of the connector 22 when pulling out or loading the PSU 13 and touches inner components with the hand only when pulling out the PSU 13 from the body housing to the large amounts after cutting the connector, thus being kept safe from the electric shock in the loading/unloading process of the PSU. |
