• The unit is rated for connection to power mains with the parameters specified in the «Technical data» section, 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 on the wire type, insulation,
length and installation method.
• Connect the unit to power mains in accordance with the wiring diagram and terminal designations.
• The external power input must be equipped with an automatic circuit breaker (QF) built into the stationary wiring to open the circuit
in the event of overload or short-circuit. The position of the external automatic circuit breaker must ensure free access for quick
power-off of the unit. 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 circuit breaker is not included in the delivery
set and can be ordered separately.
