2-5 About TB1 and SW1
2-5-1 Contents, TB1(Connector for Remote)
Be sure to read the instructions on the following page before use.
Instructions for safety
1.
Do not connect anything to PINs 7, 16, 17, 19, 23 and 24. Connection to any of these PINs
may damage the device.
2.
Do not connect PINs 5 and 10 directly to -S. (PINs 5 and 10 are connected to -output and
-S (Sens) in the power supply. These are the commons of the circuit of this power supply
unit.)
3.
Never ground PIN5, 10, 17 directory to the earth. When need to ground, ground the –(negative)
output.(connected to –(negative) output internally)
4.
Since PIN 5 is internally connected to -S output, devices to be connected to TB1 require
floating.
5.
When the positive output of the power is grounded for use, voltage approximately the same as
that of the output is applied on the pins of the TB1 connector.
Use caution since this may cause a dangerous situation.
However, PINs 6, 11, 12 and 13 are insulated from the other PINs.
For details, see 4-6-2 Status Output.
6.
Attach the cover for D-sub connector provided before use.
