Alarm code	P16
Alarm meaning	Compressor 1 (INV) overcurrent alarm
Alarm conditions	This alarm occurs when current trouble or current detection trouble occurs at an inverter frequency
	of less than 80 Hz after start (when trouble judgment current is detected 13.5 A or higher in the
	primary or secondary current).
Probable cause	There is a strong possibility of a compressor failure.

	(DCCT is damaged). In this case, the cause is a DCCT failure. The cause may be the effects of
	noise in some cases.
Check	Check the power wiring and connector wiring.
Correction	It is possible to resolve this trouble by limiting the maximum frequency.
