Mitsubishi Electric 800 Series Instruction Manual page 60

• 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 IEC 60664. 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 EN 60204-1 or IEC 60364-5-52.
• 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.)

During Operation
LD rating: -10 to +50°C
Surrounding air temperature
SLD rating: -10 to +40°C
Ambient humidity 95% RH or less
Maximum altitude 2500 m

For the installation at an altitude above 1000 m, consider a 3% reduction in the rated current per 500 m increase in altitude.
 Branch circuit protection
Class T, Class J, Class CC, or Class L fuse, or UL 489 Molded Case Circuit Breaker (MCCB) must be provided.
For the FR-F820 series, Class T, Class J, or Class CC fuse, or UL 489 Molded Case Circuit Breaker (MCCB) must be provided. (Use a product which
conforms to the EN or IEC Standard.)
