Mains connection
The unit must be disconnected from the mains before
any work is carried out!
Electrical connections may only be carried out by an
authorised specialist!
The basic electrical data of the unit are given on the
manufacturer's label.
The unit is intended for connection to a single-phase AC mains
supply of ~110-240 V/50(60) Hz in accordance with the
connection diagram.
The unit is to be connected to the power supply via insulated,
electrical power lines (cables). When selecting the appropriate
line circuit breaker, attention must be paid to the maximum
load current and the maximum wire temperature, which
depends on the conductor type, insulation, length and routing
type.
A circuit breaker built into the stationary power supply
network must be installed at the external input to interrupt the
circuit in the event of a short circuit or overload. The
installation location of the line circuit breaker must be quickly
accessible in the event of an emergency shutdown of the
ventilation system. The rated tripping current of the miniature
circuit breaker must match the current consumption of the
ventilation system, see technical data. To select the tripping
current, take the next value of the miniature circuit breaker in
the series after the maximum current consumption of the unit.
