2.3.2 Preparation
Mains connection for the PSI 9000 3U series is done via the included 5 pole plug on the back of the device. Wiring
of the plug is at least 3 strand (L1+L3+PE) or, for some models, 4 strand (L1+L2+L3+PE) of suitable cross section
and length. For recommendations for cable cross section see „2.3.4. Connection to AC supply“.
DimensioningoftheDCwiringtotheload/consumerhastoreectthefollowing:
• Thecablecrosssectionshouldalwaysbespeciedforatleastthemaximumcurrentofthe
device.
• Continuous operation at the approved limit generates heat which must be removed, as well as
voltage loss which depends on cable length and heating. To compensate for these the cable
cross section should be increased and the cable length reduced.
2.3.3 Installing the device
• Select the location for the device so that the connection to the load is as short as possible.
• Leavesufcientspacebehindtheequipment,minimum30cm,forventilation.
A device in a 19” housing will usually be mounted on suitable rails and installed in 19” racks or cabinets. The depth
of the device and its weight must be taken into account. The handles on the front are for sliding in and out of the
cabinet.Slotsonthefrontplateareprovidedforxingthedevice(xingscrewsnotincluded).
