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.
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 30 cm, 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).
Acceptable and inacceptable installation positions:
Standing surface
