Compliance with the EU Machinery Directive – Functional Safety
To achieve functional safety, any work on the product such as wiring and inspections must be performed
according to the Instruction Manual by technicians who took a safety standard training.
Warning
 Any 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 Corporation. cannot assume responsibility for any system to
comply with safety standards.
 To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged
before performing any work on the inverter. Measure the DC bus voltage between terminals P(+) and
N(-) or at test points (refer to your inverter's Instruction Manual for locations and discharging time).
The voltage must be zero.
 The safety stop function do not isolate electrically between the inverter and the motor. To avoid an
electric shock hazard, disconnect/isolate power to the inverter and verify to ensure that the voltage
is zero before performing any work on the motor (refer to your inverter's Instruction Manual for
discharging time).
