Installation and Wiring
CAUTION
• Ensure the safety programmable controller and the inverter are mounted closely in an enclosure meeting IP54 and all interconnection
wiring is short and protected against open and short circuit faults. For details, refer to ISO/IEC 13849-2.
 Installation
Safety sub-functions of the Mitsubishi Electric FR-E800-SCE inverter should be used under the following conditions and
environment.

Installation
*1 Derate the rated current when using the inverter in a temperature of 50°C or higher.
*2 Temperature applicable for a short time, for example, in transit.
*3 For installation at an altitude above 1000 m, consider a 3% reduction in the rated current per 500 m increase in altitude.
WARNING
• To avoid an electric shock hazard, install a magnetic contactor (MC) at the input side of the inverter.
• Before wiring or inspection of the inverter, open the contact of MC to switch OFF the power and check that the display of the operation
panel is OFF. Any person who is involved in wiring or inspection shall wait for 10 minutes or longer after power OFF and check the
voltage on the bus capacitors (between terminals P/+ and N/-) using a digital multimeter or other tester. The capacitor is charged with
high voltage for some time after power OFF, and it is dangerous.
