Mitsubishi Electric 800 Series Instruction Manual page 68

• Use the inverter under the conditions of overvoltage category II (usable regardless of the earth (ground) condition of the power supply), overvoltage
category III (usable with the earthed-neutral system power supply, 400 V class only) and pollution degree 2 or lower specified in IEC60664. An insulating
transformer needs to be installed in the input side of the FR-F820 series inverters.
• To use the inverter of FR-F820-01250(30K) or higher and FR-F840-00770(37K) or higher (IP00) under the conditions of pollution degree 2, install it in the
enclosure of IP 2X or higher.
• To use the inverter under the conditions of pollution degree 3, install it in the enclosure of IP54 or higher.
• To use the inverter of FR-F820-00930(22K) or lower and FR-F840-00620(30K) or lower (IP20) outside of an enclosure in the environment of pollution
degree 2, fix a fan cover with fan cover fixing screws enclosed.
• On the input and output of the inverter, use cables of the type and size set forth in EN60204 Appendix C.
• The operating capacity of the relay outputs (terminal symbols A1, B1, C1, A2, B2, C2) should be 30VDC, 0.3A. (Relay output has basic isolation from the
inverter internal circuit.)
