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 directive.
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 the 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).
Caution
The information of this manual is merely a guide for proper installation.

Mitsubishi Electric Corporation. 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.

2GENERAL DESCRIPTION
1GENERAL DESCRIPTION
Features
The safety stop function of the Mitsubishi Electric FR-A800-LC inverter can be used to prevent the inverter from
supplying rotational energy to motors. Dual input terminals S1 and S2 can be used to cut off the gate-drive power
to the IGBT.

between the inverter and the motor. To avoid an electric shock hazard, disconnect power to the
inverter and verify that the main circuit capacitor voltage is zero (across terminals P and N) before
performing any work on the motor (refer to your inverter’s Instruction Manual for discharging time).

4INSTALLATION AND WIRING
2INSTALLATION AND WIRING
Installation
The safety stop function of the Mitsubishi Electric FR-A800-LC inverter should be used under the following
conditions and environment.
Table 3 Conditions and environment for using the safety stop function
∗1 The LD ratings can be selected only for the FR-A840-LC inverter.
∗2 The SLD ratings can be selected only for the FR-A870-LC inverter.
∗3 Condensation may occur depending on the humidity and the coolant temperature. Adjust the humidity and the coolant
temperature to prevent condensation.
∗4 Temperature applicable for a short time, e.g. in transit.
To store the inverter after the coolant has passed through the pipes, fill the pipes with coolant sufficiently enough, that it
contains antifreezing agent to prevent corrosion. Or fill the pipes with nitrogen gas after the inside of the pipes is fully dried. If
any moisture remains inside the pipes, it may react with oxygen in the air to form corrosion.
∗5 Under normal condition, keep the flow rate between 3.2 and 3.5 L/m.
∗6 Under normal condition, keep the flow rate between 6.5 and 7.0 L/m.
∗7 For the installation at an altitude above 1,000 m, derate the rated current 3% per 500 m.
Caution
The following information is merely a guide for proper installation.
Mitsubishi Electric Corporation. 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.
Ensure the safety relay unit/ Safety programmable controller/ Safety controller and the FR-A800-LC
inverter are mounted closely in an enclosure meeting IP54 and all interconnection wiring is short
and protected against open and short circuit faults. Refer ISO/IEC13849-2.
