11.3.2 Surge killer for L-load
A surge killer absorbs the surge voltage generated from L-load of a magnetic contactor (MC) or solenoid
valve in the power system to effectively protect electronic equipment in the panel from malfunctions or
breakdown.
Install a surge killer near the power coil of the surge source. As shown in Figure 11.3-2 by connecting a
surge killer to the inverter's power source side, it absorbs the surge voltage from the power supply,
preventing the electronic equipment, from damage or malfunctioning. (Available capacity is 3.7 kW or
less.)
Refer to the catalog "Fuji Surge Killers/Absorbers (HS118:Japanese edition only)" for details. These
products are available from Fuji Electric Technica Co., Ltd.
Note: Do not connect the surge killers in the secondary (output) circuit of the inverter.
