EXTERNAL INPUT/OUTPUT AND FUNCTION SETTING
Notes:
●
The Demand Current Control (%) is value criterion. The value used for this control is calculated from the current, and
therefore it is different from the value indicated by a wattmeter. If it is required that the maximum power consumption is
managed precisely, a eld-supplied demand controller should be used.
●
The actual value may temporarily be higher than the indicated value (by 40% to100%) depending on the operating control
conditions such as protection control.

Notes:
●
Make the wiring to the terminals as short as possible.
●
Do not run the wirings too closely to the high voltage cable. Keep at least 30cm distance between the wiring and the high
voltage cable. (Crossing cables is okay.) If it is necessary to run the wirings closer than 30cm to the high voltage cable,
insert the low voltage cable(s) in a metal tube and ground it at one end. If sealed wirings are used at the low voltage wiring
side, ground it at one end of the shielded wirings.
●
The maximum length should be within 70m.
