WARNING
Risk from electrical voltage!
»
Electrical connection only by a trained electrician or trained and instructed qualifi ed personnel!
»
Electrical connection in harmony with the valid directives.
»
Pay attention to the 5 rules of electrical engineering:
–
clear (all-pole separation of an electrical system from live parts),
–
secure against switching on again
–
establish freedom from voltage,
–
earth and short-circuit,
–
cover or fence off neighbouring live parts.
CARE
Property damage from overheating of the motor
The motor can overheat and be destroyed if the thermo-contacts have not been connected.
