PSI 9000 DT Series
2.3.4
Connection to AC supply
•
The device can be connected to any wall socket or multi-socket outlet, as long as those feature
a grounding contact (PE) and are rated for at least 16 A.
•
When connecting the device to a multi-socket outlet, along with other electric devices, it’s
important to consider the total power consumption of all devices on the outlet, so that the
maximum current (power ÷ minimum voltage) does not exceed the definition for the wall socket,
the multi-socket outlet and/or main distribution.
•
Before plugging in the input plug ensure that the device is switched off by its mains switch!
The device is delivered with a 3 pole mains cord. If the device is going to be connected to a 2-phase or 3-phase
supply, following phases are required:
Nominal power Phases
Supply type
0.32 kW - 1.5 kW L1 or L2 or L3, N, PE
Wall socket 16 A (UK: 13 A)
The default input values of all models in this series are: 230 V, 50 Hz. Depending on the model it’s fused up to 16 A
(for particular value see technical specifications). The maximum input current depends on the higher current intake
at low AC voltage (for minimum input voltage see technical specifications). Custom made cables thus require to
have a cross section of at least 1.5 mm² (AWG16) per lead, recommended are 2.5 mm² (AWG12).
2.3.5
Connection to DC loads
• Connection to and operation with transformerless DC-AC inverters (for example solar in-
verters) is restricted, because the inverter can shift the potential of negative output (DC-)
against PE (ground), which is limited to max. ±400 V DC.
• When using any model which is rated for 40 A or higher current, attention has to be paid to
where the load is connected on the DC output terminals. The front-side 4 mm connection
point is only rated for
max. 32 A
!
• Connection of voltage sources which can generate a voltage higher than 110% nominal of
the device model isn’t allowed!
• Connection of voltage sources with reversed polarity isn’t allowed!
The DC load output is on the front side of the device and isn
’t
protected by a fuse. The
cross section of the connection cable is determined by the current consumption, cable
length and ambient temperature.
For cables
up to 5 m
and average ambient temperature up to 50°C, we recommend:
up to
10 A
:
0.75 mm² (AWG18)
up to
15 A
: 1.5 mm² (AWG14)
up to
20 A
:
2.5 mm² (AWG12)
up to
40 A
: 6 mm² (AWG8)
up to
60 A
:
16 mm² (AWG4)
per lead
(multi-conductor, insulated, openly suspended). Single cables of, for example,
16 mm² may be replaced by e. g. 2x 6 mm² etc. If the cables are long then the cross
section must be increased to avoid voltage loss and overheating.
2.3.5.1
Possible connections on the DC output
The DC output on the front is of type clamp & plug and can be used with:
•
4 mm system plugs (Büschel, banana, safety) for
max. 32 A
•
Spade lugs (6 mm or bigger)
•
Soldered cable ends (only recommended for small currents up to 10 A)
When using any type of lugs or cable end sleeves, only use insulated ones in order to
ensure electric shock protection when working with models rated 80 V or higher!
