PS 9000 2U Series
2.3.2 Preparation
Mains connection for a PS 9000 2U series device is done via the included 2 meters long 3 pole mains cord. In
case a different AC wiring is required, make sure that the other cable has at least a cross section of 2.5 mm² (AWG
12) is used.

• 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.
