K no. VF 0007). Make sure that only fuses with the required
rated current and of the specified type are used for replacement. The use of mended
fuses and the short circuiting of fuse holders should be avoided.
Supply Connections
Once the mains voltage setting and fuse have been checked, the mains supply may be
connected to the Mains Input socket of the 2313 using the Power Cable AN 0020 sup-
plied. The 2313 has a high standard of safety insulation in accordance with safety class
II of IEC 348 and therefore its chassis need not be connected to mains ground.
