(*1): Type forms of Toshiba Schneider Electric Ltd. products.
(*2): Attach surge killers to the magnetic contactor and exciting coil of the relay.
Surge killer for Toshiba Schneider Electric Ltd. magnetic contactor.
200 V class:SS-2 (Manufacture: Toshiba Schneider Electric Ltd.)
(For C11J to C65J, surge absorbing units are served optionally.)
400 V class:For the operation circuit and control circuit, regulate the voltage at 200 V or lower with a
voltage regulator.
(*3): In the case the magnetic contactor (MC) with 2a-type auxiliary contacts is used for the control circuit,
raise the reliability of the contact by using 2a-type contacts in parallel connection.
(*4): Be sure to connect DC reactor (optional) to 200V-75kW or more or 400V-110kW or more inverter.
(Not necessary for DC power input.)
