11.4 Surge Killers

11.4 Surge Killers
A surge killer absorbs surge voltage induced by L-load of an electromagnetic switch or solenoid valve. Use of a
surge killer is effective in preventing the electronic equipment, including inverters, from damage or malfunctioning
caused by such surges.
Install a surge killer near the power coil of the surge source. By connecting to the inverter’s power source side as
shown in Fig. 11.4-1, a surge killer absorbs the surge voltage, preventing the electronic equipment, from damage
or malfunctioning. (Available rated capacity of nominal applied motors is 3.7 kW or less.)
Refer to the “Fuji SD (HS189)” catalog for details. These products are available from Fuji Electric Technica Co., Ltd.
* Do not use the surge killer in the inverter secondary (output) line.
