2.3.4 Connection to DC loads
• Connection of loads which are also voltage sources and can probably generate voltages
higher than 110% nominal of the device model isn’t allowed!
• Connection of voltage sources with reversed polarity isn’t allowed!
The DC output is located on the front 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.
The DC output sockets are so-called safety sockets which allow for the use of so-
called safety plug where the protective plastic sleeve is either rigid or retractable.
Alternatively, standard laboratory cables with 4 mm Büschel plugs can be used.
Those are not suitable for currents higher than 10 A. It has to be pointed out that
the outputs 1 and 2 have identical ratings while output 3 can only deliver a small
current and power.
For cables
up to 5 m
and average ambient temperature up to 50°C, we recommend:
up to
3 A
:
0.75 mm²
up to
10 A
: 1.5 mm²
per lead
(multi-conductor, insulated, openly suspended). If the cables are long then
the cross section must be increased to avoid voltage loss and overheating.
2.3.5 Grounding of the DC outputs
The metal socket in proximity to output 1 is internally wired to PE and can be used to ground one of the DC output
poles of all three outputs by direct connection or it can be used to ground hardware which is connected as load.
2.3.6 Connecting the USB port
The device features an integrated USB port on the front. It can be connected to a PC or other suitable control
applications (PLC) via a standard USB cable (not included), in order to remotely control and/or monitor the unit.
2.3.6.1
Driver installation (Windows)
On the initial connection with a PC the operating system will identify the device as new hardware and will try to
install a driver. The required driver is for a Communication Device Class (CDC) device and is usually integrated in
current operating systems such as Windows 7 or 10. But it’s strongly recommended to use and install the included
driver installer (on USB stick) to gain maximum compatibility of the device to our softwares.
2.3.6.2
Driver installation (Linux, MacOS)
We can’t provide drivers or installation instructions for these operating systems. Whether a suitable driver is avail-
able is best found out by searching the Internet. With newer versions of Linux or MacOS, a generic CDC driver
should be “on board”.
2.3.6.3
Alternative drivers
In case the CDC drivers described above are not available on your system, or for some reason do not function
correctly, commercial suppliers can help. Search the Internet for suppliers using the keywords “cdc driver windows“
or “cdc driver linux“ or “cdc driver macos“.
