CONNECTION TO POWER MAINS
• The unit is rated for connection to 1~230 V/50 (60) Hz power mains according to the wiring diagram.
• The connection must be made using durable, insulated and heat-resistant conductors (cables, wires). The actual wire cross section
selection must be based on the maximum load current, maximum conductor temperature depending in the wire type, insulation,
length and installation method.
• The external power input must be equipped with a automatic circuit breaker built into the stationary wiring to open the circuit in
the event of overload or short-circuit. The position of the circuit breaker must ensure free access for quick unit power-off. The trip
current of the automatic circuit breaker must exceed the maximum current consumption of the unit (refer to the “Technical data”
section or to the unit label). The recommended trip current of the circuit breaker is the next current in the standard trip current row
following the maximum current of the connected unit.
• The automatic circuit breaker is not included in the delivery set and can be ordered separately.
To access the control unit, remove the service panel.
