Power and control wiring

Line	Terminal	Color	Function
Power	PE	Green/Yellow	Protective earth
Power	U1 / L	Brown	Live conductor
Power	U2 / N	Blue	Neutral conductor
Control	U3 / RSA	Brown	RS485 port
Control	U4 / RSB	Gray	RS485 port
Control	U5 / 0-10V/PWM	Yellow	0-10 VDC or PWM speed input; maximum PWM amplitude 10 V
Feedback	U6 / FG	White	Tachometer output, 5 pulses per revolution
Control	U7 / +10V	Red	External +10 VDC output
Control	U8 / GND	Blue	Reference ground

Tachometer feedback: The fan provides an open-collector speed output. The customer supplies Vfg and the pull-up resistor; Vfg = 3-30 VDC and R must be at least 1000 x Vfg ohms.

Additional Notes

Connect the power and control lines strictly according to the wiring diagram to prevent fan damage.
Do not connect the white signal wire directly to the red signal wire or an external DC power supply.
If the fan does not run after starting, check the speed-control input voltage and wiring. Do not touch the impeller or rotor after power is applied.
The fan takes several seconds to start. Do not touch the impeller or rotor while energized or operating at low speed.
For EMC compliance according to EN 55014, an additional magnetic ring is required on the power line; the ring is not supplied with the fan.
Persons lacking the required physical, sensory or mental ability, experience or knowledge may use the fan only under supervision. Keep it away from children.
A damaged power cable must be replaced by the manufacturer.
The motor is part of the fan and must not operate without an impeller or load.
After unpacking, repackage the product for storage. Store it in a clean, ventilated warehouse at -40 deg C to +80 deg C, below 95% RH, without corrosive gases, and at least 15 cm above the floor.
Read this technical specification carefully before use.
