⚫ Before connecting the cables, ensure that the instrument power switch is off
and the main switch of the AC power input (distribution box) is off.
⚫ Before connecting 3 single instruments to the AC distribution box, ensure
that the distribution box capacity is sufficient. Refer to the corresponding
specifications for the AC input parameters of a single instrument.
For 3U models, the same model can be connected in parallel. Taking three 3U
single instruments (with operation panel) as an example, the steps for parallel
operation are as follows.
2. Ensure that the power switches of the three units and the main switch of the
AC power distribution box are off.
3. Refer wiring connection diagram to connect three units.
4. Connect the AC input terminals of the three units separately, and connect
them to the AC distribution box.
5. Connect the output terminals of the three units in parallel and connect them
to the DUT.
6. Refer to the blue wiring legend in the figure, connect the System Bus (i.e.,
the fiber outer ring interfaces TX and RX) for fiber-optic communication
between the master and slaves.
a) Insert the fiber optic module into the hole corresponding to TX RX.
