						to direct sunlight and free of corrosive and explosive gases.
			Ambient temperature			-10 to +60°C (Remove the upper c over if 40°C or more, max. 60°C) [Note 4]
			Storage temperature			-25 to +70°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 114 types of signals.

Note 2: Programmable ON/OFF output terminals make it possible to arbitrarily select from 168 types of signals.

Note 3: Programmable analog output terminals make it possible to arbitrarily select from 54 types of signals.

Note 4: When using inverters where the ambient temperature will rise above 50°C, remove the upper cove r and operate each inverter at a current lower than the rated one.

12 (200V-55kW or lager and 400V-90kW or larger models dose not need remove the upper cover) Note 5: This function protects inverters from overcurrent due to output circuit ground fault.
