Page 3: General Description
GENERAL DESCRIPTION Features The safety stop function of the Mitsubishi Electric FR-A800/F800 inverter can be used to prevent the inverter from supplying rotational energy to motors. (In this Instruction Manual, the STO (safe torque off) function specified in IEC 61800-5-2 is referred to as the safety stop function.) Dual input terminals S1 and S2 can be used to cut off the gate-drive power to the IGBT. - Page 4 Safety stop function with SIL 3 certification The Mitsubishi Electric FR-A800/F800 inverters now comply with safety integrity level 3 (SIL 3) of the IEC EC61508:2010 functional safety standard. • Target models Mitsubishi Electric FR-A800/F800 inverters • Change of the compliance The Mitsubishi Electric FR-A800/F800 inverters now comply with SIL 3.

Page 5: Installation And Wiring
IP54 and all interconnection wiring is short and protected against open and short circuit faults. Refer ISO/IEC13849-2. Installation The safety stop function of the Mitsubishi Electric FR-A800/F800 inverter should be used under the following conditions and environment. Table 2 Conditions and environment for using the safety stop function... - Page 6 Warning To avoid an electric shock hazard, insert the magnetic contactor (MC) between power source and inverter. Open the contact of MC and keep away from the inverter for discharging time (refer to your inverter’s Instruction Manual for information) before performing any work on the inverter. And verify that the voltage on the bus capacitors has discharged before measuring the DC bus voltage between terminals P(+) and N(-) or at test points (refer to your inverter’s Instruction Manual for locations).

Page 12: Test And Checking Failure
TEST AND CHECKING FAILURE Caution To avoid system faults, check the safety stop function at least once per year. To comply with SIL 3, the safety stop function must be checked at least once in three months. Also, check the safety stop function at system installation, any software changes, and parameter setting changes. -
