Connection of motors

Motors are equipped with protecting thermocontacts
which protect the motor from overheating. Thermocon-
tacts must be connected according to specified conne-
ction.
Single-speed motors are designed for 230V D/400V Y
power supply voltages and connections for electro mo-
tors with output up to 3kW.
Motors are in production wired to wiring box on casing
of fan section. They are standardly intended for voltage
3x 400 V / 50 Hz.
If the delivery contains frequency inverter for control of
motors with output up to 1,5 kW, the electric connection
is then 1x 230 V / 50 Hz.
The same frequency inverter connection applies for
control of two motors up to 0.75 kW (including). The
frequency inverter connection for control of two 1.1 kW
motors is 3x 400V/50 Hz.
If the single-speed motor is additionally connected to an
output controller (frequency inverter), it is necessary to
check, respectively reconnect the motor wiring (correct
connection Y/D in the motor terminal box) in relation to
the power supply voltage (230/400V).
