Cautions And Notices - Danfoss Vacon OPTEA Operating Manual

VACON® NXP Advanced Safety Options
Operating Guide
SHOCK HAZARD FROM CONTROL TERMINALS
The control terminals can have a dangerous voltage also when the drive is disconnected from mains. A contact with this voltage
can lead to injury.
-
Make sure that there is no voltage in the control terminals before touching the control terminals.
ACCIDENTAL MOTOR START
When there is a power-up, a power break, or a fault reset, the motor starts immediately if the start signal is active, unless the pulse
control for Start/Stop logic is selected. If the parameters, the applications or the software change, the I/O functions (including the
start inputs) can change. If you activate the auto reset function, the motor starts automatically after an automatic fault reset. See
the Application Guide. Failure to ensure that the motor, system, and any attached equipment are ready for start can result in
personal injury or equipment damage.
-
Disconnect the motor from the drive if an accidental start can be dangerous. Make sure that the equipment is safe to operate
under any condition.
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the drive properly can result in death or serious injury.
-
Ensure the correct grounding of the equipment by a certified electrical installer.
SHOCK HAZARD FROM PE CONDUCTOR
The drive can cause a DC current in the PE conductor. Failure to use a residual current-operated protective (RCD) device Type B or
a residual current-operated monitoring (RCM) device can lead to the RCD not providing the intended protection and therefore
can result in death or serious injury.
-
Use a type B RCD or RCM device on the mains side of the drive.

2.3 Cautions and Notices

DAMAGE TO THE AC DRIVE FROM INCORRECT MEASUREMENTS
Doing measurements on the AC drive when it is connected to mains can damage the drive.
-
Do not do measurements when the AC drive is connected to mains.
DAMAGE TO THE AC DRIVE FROM INCORRECT SPARE PARTS
Using spare parts that are not from the manufacturer can damage the drive.
-
Do not use spare parts that are not from the manufacturer.
DAMAGE TO THE AC DRIVE FROM INSUFFICIENT GROUNDING
Not using a grounding conductor can damage the drive.
-
Make sure that the AC drive is always grounded with a grounding conductor that is connected to the grounding terminal
that is identified with the PE symbol.
