PSB 9000 3U Series
2.3.2 Preparation
Mains connection for the PSB 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 (2x L, PE) or, for some models, 4 strand (3x L, PE) of suitable cross section and length.
Connecting all conductors (3 phase, N, PE), though not required, is totally acceptable and is even recommended,
because the cable could then be used for any other device model or series with the same type of AC connector
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 reect the following:
• The cable cross section should always be specied 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 resp. external source is
as short as possible.
• Leave sucient space behind the equipment for ventilation, at least 30 cm.
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).
On some models the mounting brackets provided to x the device in a 19” cabinet can be removed so that the
device can be operated on any at surface as a desk top device.
Acceptable and inacceptable installation positions:
Standing surface
