Interlock Interlocking is required for control circuit so that control order should not suppy to both A power source side and B power source side simultaneously. For TN type ATS, Sequence setting is required so that closing or tripping order should not supply in the same direction. Control Circuit ATS is designed so that operation current should be off by internal switch after completion of operation.

Safety Manual Safety Notice This safety manual describes major informations for safe operation. Before handling this machinery, please be acquainted thoroughly with this manual.

26 Safety Manual Safety Notice This safety manual describes major informations for safe operation. Before handling this machinery, please be acquainted thoroughly with this manual. product handling, safety information and all other precautions before installation or maintenance. Emergency situation, which may cause death or serious disaster if there is mistake. A potentially problematic situation, which may cause slight personal injury and/or damage. These safety notices are devided as "Danger" and "Caution" according to the hazard level. Transportation Precaution Do not enter the area under the Automatic Transfer Switches (ATS) when it is lifted or suspended using a lifter or chain block. The ATS may suddenly drop. The ATS is heavy. Entering such an area may cause serious injury. Installation Precautions Installation should be performed by qualified persons. Prior to commencing any installation, open the upstream circuit breaker to isolate all power/voltage sources. Otherwise, electric shock may occur. Tighten terminal screws securely according to the specified torque. Otherwise, a fire may occur. Fix the Drawout type ATS firmly on a flat level using mounting screws. Otherwise, drawout operation may cause the ATS to fall. Avoid blocking of ATS's arc gas vents to ensure the adequate arc space. Blocking of the arc gas vents could result in failure of ATS. Do not place the ATS in such area of high temperature, high humidity, dusty air, corrosive gas, strong vibration and shock or other unsual conditions. Installation in such areas could cause a fire or malfunction. Be careful to prevent foreign material of debris, concrete powder, iron powder, etc and rainwater from entering into the ATS. These materials inside the ATS could cause a fire or malfunction. For 4 pole ATS, connect the neutral wire of 3phase, 4wire cable to Nphase (on the right side). 26 I Automatic Transfer Switches

Operation Precautions Do not touch the live terminal parts. Otherwise, electric shock may occur. Do not leave the ATS in the drawout position. The ATS is heavy.

ATS should be operated by manual handle only under noload condition. Operation by manual handle is strictly prohibited except emergency case. Otherwise, damage to the ATS may occur.

27 Operation Precautions Do not touch the live terminal parts. Otherwise, electric shock may occur. Do not leave the ATS in the drawout position. The ATS is heavy. Dropping the ATS could cause serious injury. The cable size of control power should be selected considering operation current. Otherwise, a fire could occur. ATS should be operated by manual handle only under noload condition. Operation by manual handle is strictly prohibited except emergency case. Otherwise, damage to the ATS may occur. Maintenance and Inspection Precautions Maintenance, inspection or components replacement should be performed by qualified persons. Prior to commencing any work, open the upstream circuit breaker to isolate all power/voltage sources. Otherwise, electric shock may occur. Prior to commencing internal inspection for ATS, Be sure that main circuit and control source of ATS should be off. Otherwise, fingers or tools could be pinched in the internal mechanism, causing injury. Retighten the terminal screws periodically according to the specified torque. Otherwise, a fire may occur. Retighten the arcing contact mounting screws periodically according to the specified torque. Otherwise, a fire or malfunction may occur. Be sure to reinstall the arc chute if removed. Failure to do so or incorrect installation may result in a fire or cause of burns. Do not touch the live parts or structural parts close to live parts immediately after stop of power supply to ATS. Otherwise, remaining heat may cause burns. Do not approach near the arc gas vent of arc chute while ATS is under transfer. Otherwise, burns may result from high temperature of arc gas.
