3. After setting of host and slave, switch off the power supply. Connect the

networking.

Connect the networking as shown above. Please connect the network after

parallel setup. Otherwise, at start up, the power supply will detect parallel setup

fault and fail to start up.

 When connecting the system bus, please note the built-in terminal

matching resistance at the rear panel. If the resistance is removed,

the instrument may not work properly. The user can install the

terminal matching resistance on the Input end of the first system bus

and the Output end of the last system bus.

 The system bus interface is not isolated from the output electrode.

After power on, it is not allowed to insert or pull out the bus and

terminal matching resistance.
