PSI 9000 WR 3U Slave Series
2.3.2.2 AC supply
AC supply connection for power supply is done via the included 5 pole plug on the rear of the device. Wiring of
the plug is always 4 strand (L1+L2+L3+PE) of suitable cross section and length. For recommendations for cable
„2.3.4. Connection to AC supply“.
2.3.2.3 DC output
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).
Acceptable and inacceptable installation positions:
Standing surface
Models of this series can be combined with suitable models of other series like PSI 9000 3U
or PSI 9000 3U Slave in parallel connection, but when installing the mixed setup into a cabinet
the increased depth of the WR has to be considered.
