(IVR
): Variable speed compressors (INVERTER)
THIS MACHINE IS DESIGNED TO BE CONNECTED TO TWO DIFFERENT SOURCES OF ELECTRICAL POWER: THREE-PHASE
POWER SOURCE FOR COMPRESSOR, SINGLE PHASE POWER SOURCE FOR DRYER
READ THIS MANUAL CAREFULLY BEFORE PERFORMING ANY OPERATIONS ON THE AIR COMPRESSOR.
ATTENTION: THE CAPACITORS INSIDE THE INVERTER MAY REMAIN LIVE FOR 15 MINUTES AFTER THE MACHINE HAS BEEN
DISCONNECTED FROM THE MAINS POWER.
ACTING ON THE INVERTER BEFORE 15 MINUTES HAVE PASSED MAY ENTAIL THE RISK OF ELECTROCUTION AND DEATH.
