Refer ISO/IEC13849-2. 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... - 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 the terminals P(+) and N(-) or at test points (refer to your inverter’s Instruction Manual for locations).

Page 14: 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. -

NOTE • The response time from safety stop signal input to drive shutoff (safe state) is faster than 8ms. • Hold the ON or OFF status for 2 ms or longer to input signal to terminal S1 or S2. Signal input shorter than 2 ms is not recognized. Diagnostic If a failure is detected, the FR-A800-LC inverter outputs a fault signal and ‘E.SAF’... - Page 16 MEMO...
