(c) Wiring for parallel operation with remote sensing
Example of connecting remote sensing circuits in parallel operation
are shown in Fig. 5.5. Refer to section 4.8 "Remote sensing" how to
use this function.

(d) Wiring for parallel operation with remote control
Example of connecting remote ON/OFF circuits in parallel operation
are shown in Fig. 5.6 and Fig. 5.7. Refer to section 4.7 "Remote
ON/OFF" how to use this function.
In this case, accumulated current (N×I_RC1) flows to the control
switch.

(e) Wiring for parallel operation with constant current adjustment
The constant current adjustment can be used in parallel operation. By
changing the ITRM voltage of one unit, the constant current adjustable
for all of units.
It is not necessary to connect the ITRM terminals together. Examples
of connecting constant current circuit in parallel operation are shown
in Fig. 5.8 and Fig. 5.9. Refer to section 4.9 "Adjustable constant
current range " how to use this function.

potentiometer

external voltage
5.3 Redundancy operation
By choosing option -O, ORing MOSFET is implemented into the unit.
Therefore, it is possible to connect each output directly for N + 1
redundancy operation.
See section 7.2.
