INSTALLATION AND WIRING

CAUTION
 The following information is merely a guide for proper installation.
Mitsubishi Electric 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 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. Refer ISO/IEC 13849-2.
Installation
The safety stop function of the Mitsubishi Electric FR-E800(-E) inverter should be used under the following conditions and
environment.


Derate the rated current when using the inverter in a temperature of 50°C or higher.

Temperature applicable for a short time, e.g. in transit.

For the installation at an altitude above 1,000 m, derate the rated current 3% per 500 m.
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). The
voltage must be zero.
CAUTION
 In order to meet safety standards, a safety relay module compliant with ISO 13849-1 safety category
3 or higher shall be used in conjunction with the FR-A800/F800 inverter (refer to
addition, all other components in the safety stop loop shall be 'safety approved' types.
 To avoid system faults, check the safety stop function at least once per year.
Also, check the safety stop function at system installation, any software changes, and parameter
setting changes. For details, refer to Chapter 4 TEST AND CHECKING FAILURE.
