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.
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. Dual input terminals S1 and S2 can be used to cut off the gate-drive power to the IGBT.

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.
A hazard of personal injury and/or equipment damage exists if codes are ignored during installation. Ensure the safety relay unit and the FR-A800/F800 inverter are mounted closely in an enclosure meeting IP54 and all interconnection wiring is short and protected against open and short circuit faults.

Also, check the safety stop function at system installation, any software changes, and parameter setting changes. I/O status and inverter operation The FR-A800/F800 inverter’s safety related I/O status obeys the following truth table. Table 6 Truth table of safety related signals Output...
3) If the inverter operates as described in Table 6, check the system performance. Press the emergency switch, press the start/restart button while a failure is detected (So (SO) -SOC opened), and so on. 4) Finally clear the fault history of the FR-A800/F800 inverter (see the Instruction Manual for how to clear the fault history).
