DANGER
Life-threatening danger due to electric shock
Live units and exposed connection cables can generate an electric shock and cause severe accidents.
 Work on electrical connections must be carried out exclusively by trained, qualified electricians.
 Ensure that the unit is voltage-free before routing all electrical connections.
Note
The compressor can be destroyed if the phase sequence is incorrect
 Always check the phase sequence before commissioning the three-phase unit.
 Ensure that the phase sequence rotation is clockwise.
