PS 9000 3U Series
2.3.2 Preparation
Mains connection for the PS 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 wire (L2+L3+PE) or, for some models, 4 wire (L1+L2+L3+PE) of suitable cross section
and length. It’s allowed to wire the N conductor of a standard three-phase cable to the remaining input pin. 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 su󰀩cient space behind the equipment, minimum 30cm (1 ft), for ventilation.
A device in a 19” housing is designed to be installed in 19” racks or cabinets, which are either lockable or at least
have closable doors. This is required to achieve a su󰀩cient protection against touching parts leading dangerous
voltage.
The device can rest on rails or a shelf. When selecting those the depth of the device and its weight must be taken
into account. The handles on the front are intended to help sliding it in or out of the cabinet. Slots on the front plate
are provided for xing the device (xing screws not included).
Acceptable and unacceptable installation positions:
Standing surface
