Changing maximum frequency

I use the FR-B-37K and 45K inverters. While the maximum frequency over 30 kW is 60 Hz, can I perform test operation at 80 Hz?
If possible, how can I do it?
Inverter type: FR-B-37K, 45K (derivation from A240E)
Category : 


The FR-B type 30K or higher products have passed the explosion-proof test certified by the Ministry of Health, Labour and Welfare with the maximum frequency set to 60 Hz. Therefore, the maximum frequency cannot be changed by the parameter.

Operation with this maximum frequency changed invalidates the certificate by the Ministry of Health, Labour and Welfare and you need to pass the test again.
You cannot perform test operation by changing the maximum frequency. (For test operation, use a general-purpose inverter.)
