(*1) Even if the unit is used within the permissible power voltage fluctuation range, the PQ output characteristics may deteriorate if the power voltage fluctuates to the negative side. Also note that power voltage fluctuation to the positive side may cause alarms, due to overloading of regenerative operation, depending on the operation conditions. You are therefore recommended to use the unit in an environment with limited power voltage fluctuation as far as possible. (*2) With the S-SUT00S25018 and S-SUT00S30018 specifications, the DC 24 V control power (0.2 A minimum) needs to be input at...
