2-7 Remote Interface Connector (TB1) and Function Setting Switch (SW1)
2-7-1 Remote Interface Connector (TB1)
This product is a power supply unit that generates a large current.
If a large current flowed into TB1 due to an incorrect connection, there might be a risk of
failure or burnout.
Be sure to confirm the following precautions before use.
Do not connect anything to PIN 4, 8, 9, 14, 18, 20, 22, 23, 24, and 25.
Doing so may lead to unit damage.
Do not directly connect PIN 5 and PIN 10 to the -S.
Do not directly ground PIN 5 and PIN 10 to the ground.
When grounding, connect the "-" output terminal to the ground.
Do not wire near sources of large noise. Doing so may result in malfunction or
breakdown.
(Note) If the above situation is unavoidable, it is recommended to use the -LGob
option (Optical GPIB/RS-232C interface board).
PIN 5 and PIN 10 are internally connected to -S. Therefore, equipment connected to
TB1 should be floating.
The wiring from the following pins should be short ( a few meters or lower).
TB1 PIN 1, 2, 3, 5, 7, 10, 15, 16, 17, 21, 26
When using this unit with the "-" output terminal grounded, a voltage equal to the output
will be applied to TB1 pins. Be careful because this may be dangerous.
However, PINs 6, 11, 12, 13, 19, and 26 are insulated from other PINs.
For details, refer to [7-4-2 Status Output].
Do not connect PIN 5 or PIN 10 on the
TB1 to the "-" output.
Do not share the common for the external
voltage input of each unit when connecting
the units in series.
