8. Peripherals
(b) Compensate with AGC or Auto-cal function
If the voltage waveform is not distorted, the voltage drop can be compensated. When output is
unstable in case a), the stabillity may be improved.
Connect between the FEEDBACK connector of DIP or RIN and the sensing input terminal of
this product with the feedback cable included in DIP or RIN.
Set the remote sensing function of this product to ON, and set AGC or Autocal (See 4.12,
4.13).
WARNING
 Turn off this product including its peripherals before connecting or disconnectiong the cable. Be
sure to turn off this product and switch off the breaker at the distribution board. Otherwise, an
electric shock might occur and it may damage the load and this product.
CAUTION
 For the polyphase system, cables should be connected to the sensing input terminals for each
phase.
 Place DIP or RIN near this product.
 The cable connecting between the output terminal of this product and the input terminal of DIP
or RIN should be as short as possible (3 m or less) and use twisted or parallel.
 Be sure to wire the feedback cables correctly to the DIP or RIN FEEDBACK connector and the
sensing input terminal of this product. If you turn on the output of this product while the
feedback cable is not connected to the sensing input terminal of this product correctly, this
product cannot control the output, and excessive voltage may be applied to the load.
 Before connecting the load to the output terminal of DIP or RIN, wire this product with DIP or
RIN and turn on the output of this product, and then check matching the output voltage at the
terminal of DIP or RIN and the setting voltage of this product.
-------- Notes ------------------------------------------------------------------------------------------------------------
 When setting remote sensing function to FB to compensate for the voltage drop, the output
voltage may become unstable depending on the load and the wiring to the load.
