Maximum Current Value Change Function
The maximum current value is changed to 14A (for C3082) or 17A (for C3682) to prevent power breaker tripping. (It is set to 24A when the unit is delivered from the factory.)
NOTE 1. When the high load is given (Outside temperature is high in the cooling operation), the capacity is reduced.
When the maximum current value change function is to be enabled, make sure to receive the approval of the client.
2.The maximum capacity for cooling operation is about as much as the rated capacity.

•Operates at the target frequency at Point A and below.
•Stops increases to the frequency between Points A and B.
•Reduces the frequency by 1 Hz per 0.5 seconds when Point B is exceeded.
•Stops operation, and restarts it appoximately 5 minutes later, if Point C is exceeded.
(May operate when sudden voltage fluctuations occur.

<Maximum Current Value Change Procedure>
(1)Remove the inspection panel.
Refer to Fig. 2 in " 
Noise Reducing Control" for details.
(2)When the switch No.2 of the dip switch (SW01) on the control P.C.Board is turned ON, the maximum current value change. (Fig. 4)
