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.
