Compliance with the EU Machinery Directive – Functional SafetyDANGERAny misuse of safety function could lead to personal injury or death, property damage, or economic loss. To ensure that the system complies fully with requirement of safety, make a system-level risk assessment.
Mitsubishi Electric Co. Cannot assume responsibility for any system to comply with safety directive.ATTENTIONThe information of this manual is merely a guide for proper installation.Mitsubishi Electric Co. Cannot assume responsibility for the compliance or the noncompliance to any code, national, local or otherwise for the proper installation of this equipment.A hazard of personal injury and/or equipment damage exists if codes are ignored during installation.DANGERTo avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged before performing any work on the drive. Measure the DC bus voltage at the P(+) and N(-) terminals or test points (refer to your drive’s User Manual for locations and discharging time). The voltage must be zero.DANGERThe safety stop function do not isolate electrically between drive and motor.
To avoid an electric shock hazard, disconnect/isolate power to the drive and verify to ensure that the voltage is zero before performing any work on the motor (refer to your drive’s User Manual for discharging time).ATTENTIONIf you are using a FR-D740-EC or FR-D740-CHT with serial number shown below, safety function does not work according to safety standard. In such case please contact your sales person.D740-012 to 080 –EC: Axxxxx, Bxxxxx, Cxxxxx, Dxxxxx, Exxxx and Fxxxxx D740-120 to 160 –EC: Axxxxx, Bxxxxx, Cxxxxx and DxxxxxD740-0.4K to 3.7K –CHT: Axxxxx, Bxxxxx, Cxxxxx, Dxxxxx,Exxxx and Fxxxxx D740-5.5K to 7.5K –CHT: Axxxxx, Bxxxxx, Cxxxxx and Dxxxxx.
