CONNECTION TO POWER MAINS
CONNECTION OF ADDITIONAL EXTERNAL CONTROLS
• The unit is rated for connection to 1~230 V/50 (60) Hz power mains.
• The unit must be connected to power mains using insulated electric conductors (cables, wires). The actual wire cross section selection
must be based on the maximum load current, maximum conductor temperature depending on the wire type, insulation, length and
installation method.
• The external power input must be equipped with an automatic circuit breaker built into the stationary wiring to open the electric
circuit in case of overload or short-circuit. The circuit breaker installation place must provide quick access for emergency shutdown
of the unit. The trip current of the automatic circuit breaker
QF
must exceed the maximum current consumption of the unit (refer
to the technical data table). 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.
