CAUTION
For the user's own safety, this frequency inverter must be connected to an approved earth (
B
terminal).
Power electronic equipment such as speed controllers, frequency inverters, soft starters, and inverters cannot be used as
circuit-breaking or isolating devices as specified in standard EN 60204 - 1, section 5.
If an accidental start of the installation represents a risk for personnel or the machinery to be driven, it is imperative to supply the
equipment via an isolating device and a circuit-breaking device (power contactor) controllable by an external safety system
(emergency stop, fault detector).
The frequency inverter is fitted with safety devices which can stop the frequency inverter in the event of faults or even stop the
motor. The motor itself can be jammed by mechanical means. Finally, voltage fluctuations, and particularly power cuts, can also
cause the starter to switch off.
The removal of the cause of the shutdown can lead to restarting, with consequent hazard for certain machines or installations.
In such cases, it is essential that the user takes appropriate precautions against restarting when the motor makes an
unscheduled stop.
This equipment meets with existing construction standards. Nonetheless it may cause interference, and the user is responsible
for carrying out the appropriate action to eliminate such interference.
The frequency inverter is designed to power a motor over and above its rated speed (up to 19 times with some settings).
If the motor is not mechanically capable of operating at such speeds, the user risks serious damage arising from mechanical
deterioration of the motor.
Before programming a high speed, it is essential that the user ensures that the motor can tolerate it.
LEROY-SOMER declines all responsibility in the event of the above recommendations not being observed.

DANGER
IMPORTANT
Before any intervention, whether to do with the electrics or the mechanics of the installation or machine :
- ensure that the power to the inverter has been switched off (fused isolator or circuit-breaker) and locked manually.
- wait 7 minutes before working on the associated frequency inverter,
- indicates sections in this manual relating to the safety of workers.
