• 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 60204-1, 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
• Environment (For the detail, refer to
Surrounding air temperature
Ambient humidity
Maximum altitude
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 fuses, or UL 489 Molded Case Circuit Breaker (MCCB) must be provided.
For the FR-A820 series, Class T, Class J, or Class CC fuses, or UL 489 Molded Case Circuit Breaker (MCCB) must be provided.
(Use a product which conforms to the EN or IEC Standard.)
