Mitsubishi Electric FR-A820-04750-GF Instruction Manual page 79

• To use the inverter of FR-A820-01250(22K) or lower and FR-A840-00620(22K) 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 and IEC 60364-5-52.
• The operating capacity of the relay outputs (terminal symbols A1, B1, C1, A2, B2 and C2) should be 30 VDC, 0.3 A. (Relay output has basic isolation from
the inverter internal circuit.)
• Control circuit terminals on page 4
• Environment (For the detail, refer to
LD, ND (initial setting), HD: 0 to +50°C
Surrounding air temperature
SLD: 0 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-A820 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.)
