Q apr Installation AC Power Source Connections AC Input Wiring ACDC Power Supplies Warning If the same AC power source is used provide AC power other s in a Sysm ensure that all AC input connections are identical at ea rack. Do not cross Line L and Line L. A resulting difference in pontial can injure personnel or cause dage equipment. Ea must be connecd a mon ground. Ensure that the proctive cover is instald over all boards. During norl operation with an AC power source either VAC or VAC is present on the AC Power Supply. The cover procts against accidental shock hazard whi could cause severe or fatal injury the operar or innance personnel. Both the Standard ICPWR and High Capacity ICPWR ACDC power supplies currently have six s for user connections. Early versions of some power supplies had five s see next figure. The wiring methods for both five and six types is similar except that sp below does not apply the five type. The power supply boards will accept one AWG # . mm or two AWG # . mm copper _ C _ F s. Ea can accept solid or stranded s but the s in any given should be the same type. The suggesd rque for the power supply board is inlbs . Newnmers. Open the door procting the board and ke the following connections from the AC power source and ground connections sysm grounding requirements are described in detail lar in this apr. . These are wide range supplies that can opera from an AC power source within the nominal range of VAC VAC at Hz. This y vary + for a tal range of VAC VAC. These are auranging supplies that do not require jumper or swit settings for section of power source voltage. . Connect the hot and neutral s or lines L and L the upper two s on the board.
