Using In Combination With Dip Or Rin; The Case The Voltage Drop Due To Wiring Is Small; Compensating The Voltage Drop By The Feedback Connector Of Dip Or Rin - NF DP420LS Instruction Manual

8.2

Using in combination with DIP or RIN

When using this product in combination with DIP or RIN, connect between CONTROL I/O
connector and CONTROL IN connector of this product with the attached control cable (25 pin) and
connect CONTROL SIGNAL connector of this product and DIP or RIN with the control cable
included in DIP or RIN. Also set external control function to DevCtrl.
For detail on how to use DIP or RIN, refer to the respective instruction manual.
8.2.1

The case the voltage drop due to wiring is small

(a) The case measuring with the output terminal of this product
The feedback cable included in DIP or RIN and the FEEDBACK connector of DIP or RIN are
not used. Turn off the remote sensing function of this product.
(b) The case measuring with the sensing input terminal of this product
This product measures the voltage at the FEEDBACK connector of DIP or RIN. 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. Turn on the remote sensing function of
this product.
WARNING
 Turn off this product including its peripherals before connecting or disconnecting 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.
8.2.2 Compensating the voltage drop by the FEEDBACK connector of DIP
or RIN
(a) Compensate when setting remote sensing function to FB
By changing the voltage feedback detection point from the inside of this product to the external
(sensing input terminal), the output voltage at the FEEDBACK connector of DIP or RIN can be
compensated.
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 FB. (See 4.11.)
