The ventilator is rated for connection to single-phase AC 100-240 V/50 (60) Hz power mains.
The ventilator is connected to power mains using insulated, durable and heat-resistant conductors (cables, wires) with a cross section of
at least 0.5-0.75 mm2 through the automatic circuit breaker with a magnetic trip built into the stationary wiring. The circuit breaker trip
current must be selected depending on the ventilator current consumption. For details, please refer to the table on page 5.
The actual conductor cross-section selection must be based on its type, maximum permissible heating, insulation, length and installation
method.
When choosing a signal cable, follow these guidelines:
• Always use a shielded cable.
• The cross-section of the conductors, depending on the length, is selected according to the table below.
