PROTECTIVE FEATURES
Short-circuit protection:
The motor and electronic controller are protected against short-circuit by built-in fuse.
Locked-rotor protection:
As soon the rotor is blocked, the motor is switched off electronically. After de-blocking, the motor will restart automatically.
Mains under voltage:
If mains voltage falls below the nominal value the motor will keep running with degraded performance. Below 320V, the motor will be switched off
electronically in stand-by mode. When mains voltage returns to correct value, the motor will restart automatically.
In the specific case, the undervoltage protection may switch off the fan to stand-by mode, for example, fan running or testing at high pressure drop and
low voltage.
Over temperature protection:
Internally connected thermal protector to protect electronic and motor against over temperature.

PUTTING INTO OPERATION
Before first start you should check:
a. Appropriate installation and electrical connection, especially resistance of the protective-earth (PE) circuit (max. 100m
Ω
).
b. If safety equipment is in place and motor protection device is in function.
c. If the impeller can rotate freely once the unit is mounted and the right direction of rotation is assured.
Only if all dangerous situations are excluded, the fan may be put into operation!
Switch ON the power supply.
Switch ON the device via the control signal and apply the speed setting voltage/signal and check the direction of the rotation and the smoothness of
running.
