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 safety contact (PE) and are rated for 16 A.
• When connecting the device to a multi-socket outlet, along with other electric devices, it is
important to consider the total power consumption of all devices on the outlet, so that the maxi-
mumcurrent(power÷minimumvoltage)doesnotexceedthedenition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 standard 2-phase or
3-phase supply, following leads and 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 is fused with
upto16A(forparticularvalueseetechnicalspecications).Themaximuminputcurrentdependsonthehigher
currentintakeatlowACvoltage(forminimuminputvoltageseetechnicalspecications).Custommadecables
thus require to have a cross section of 1.5 mm² (AWG16) minimum per lead, recommend is 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 4mm 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 is not allowed!
• Connection of voltage sources with reversed polarity is not allowed!
The DC load output is on the front side of the device and is not 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: 4 mm² (AWG10) up to 40 A: 10 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 sec-
tion 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)
