CAUTION
Emergency stop
 A safety backup such as an emergency brake must be provided for devices or equipment in a system to prevent
hazardous conditions in case of failure of this product or an external device controlling this product.
 If the breaker installed on the input side of this product trips, check for wiring faults (such as short circuits) and damage
to internal parts of this product. Identify and remove the cause of the trip before resetting the tripped breaker (or before
applying the power to this product again).
 When any protective function is activated, take an appropriate corrective action before resetting this product to resume
the operation.
Maintenance, inspection and parts replacement
 Do not carry out a megger (insulation resistance) test on the control circuit of this product. Doing so will cause failure.
Disposal
 This product must be treated as industrial waste.
Compliance with the EU Machinery Directive—Safety functions
To achieve functional safety, any work on the product such as wiring and inspections must be performed according to this
document and the FR-E800-SCE Instruction Manual (Functional Safety) by technicians who took a safety standard training.
WARNING
 Any misuse of safety functions may cause physical injury, damage to property, or economic loss. To confirm that the
system is compliant with safety standards, a risk assessment must be conducted for the entire system. We shall not be
liable for the compliance of the system with safety standards.
 To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged before working on the
inverter. Measure the DC bus voltage between terminals P/+ and N/- or other measurement points to verify zero voltage.
(For the measurement points and the capacitor discharge time, refer to the FR-E800 Instruction Manual (Maintenance).)
 When the power supply to the gate drive circuit is shut off by a safety function, the inverter and the motor are not insulated
each other. To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged before wiring
or inspection of the motor. Measure the DC bus voltage between terminals P/+ and N/- or other measurement points to
verify zero voltage. (For the measurement points and the capacitor discharge time, refer to the FR-E800 Instruction
Manual (Maintenance).)
CAUTION
 We shall not be liable for the compliance or non-compliance with any local, national, or international codes or regulations
for the installation of this product.
 Installation not compliant with applicable codes or directives may cause physical injury or damage to property.
General instruction
 For clarity, illustrations in this Instruction Manual may be drawn with covers or safety guards removed. Ensure all covers
and safety guards are properly installed prior to starting operation. For details on the PM motor, refer to the Instruction
Manual of the PM motor.
