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 reflect the following:
•
The cable cross section should always be specified 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 sufficient 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 fixing the device (fixing screws not included).
On some models the mounting brackets provided to fix the device in a 19” cabinet can be removed so that the
device can be operated on any flat surface as a desk top device.
Acceptable and inacceptable installation positions:
Standing surface
