Communication function
RS-485 standard 2-channel equipped (connector: modular 8P)
CC-Link, DeviceNet and PROFIBUS-DP are optional.
Use environments Indoor use. Altitude: 3000m or less (current reduction necessary if 1000m or more.) Place not exposed to
direct sunlight and free of corrosive and explosive gases.
Ambient temperature -10 to +60°C (Remove the upper cover if 40°C or more, max. 60°C) Note 4:
Storage temperature -25 to +65°C
Relative humidity 20 to 93% (free from condensation)

Note 1: 16 contact input terminals (of which 8 are options) are programmable contact input terminals, and they make it
possible to arbitrarily select from 136 types of signals.
Note 2: Programmable ON/OFF output terminals make it possible to arbitrarily select from 150 types of signals.
Note 3: Programmable analog output terminals make it possible to arbitrarily select from 55 types of signals.
Note 4: When using inverters where the ambient temperature will rise above 50°C, remove the upper cover and
operate each inverter at a current lower than the rated one.
Note 5: Inverters, 18.5kW or greater, do not have wiring port covers. They have large openings, but there is no space
to bend the external cables inside the unit. If they are fitted external to the cabinet, please use an optional
wiring port cover.
Note 6: This function protects inverters from overcurrent due to output circuit ground fault.
