.. _input-ac: AC Input Connection ------------------- A single-phase AC input connection is used to provide a ground reference and power for the |product_type| fans and control circuits. The AC input power requirements are defined on the |product_full| product rating label. The AC input requirements are further defined in this section. To provide AC power to the |product_full|, connect the provided power cord to the IEC 60320 C13 AC power receptacle, as shown in :ref:`fig-installation-power-plug-c13`. .. _fig-installation-power-plug-c13: .. figure:: _common-all/_images/installation-power-plug-c13.* :width: 200pt :align: center |product| IEC 60320 C13 AC power receptacle .. warning:: The power cord provides a chassis ground through the third conductor. Be certain that your power outlet is of the three-conductor type with the correct pin connected to earth ground. Fuse Rating ^^^^^^^^^^^ The |product_full| is fused on its auxiliary power supply assembly, which is a printed circuit board (PCB) assembly located inside the product. The fuse can be accessed by removing the |product_full| top cover and locating the only PCB assembly inside. The fuse is a through-hole component designated by F3 on the PCB. This fuse carries a 3.15 Aac rating, Bussmann / Eaton manufacturer part number SS-5H-3.15A-APH, Magna-Power Item 32060. Failure of this fuse typically indicates a failure of this auxiliary power supply assembly and it's recommended to contact Magna-Power support in the event this fuse has cleared.
