Operating Guide | VLT® AQUA Drive FC 202
HOT SURFACES
The drive contains metal components that are still hot even after the drive has been powered off. Failure to observe the high
temperature symbol (yellow triangle) on the drive can result in serious burns.
Be aware that internal components, such as busbars, may be extremely hot even after the drive has been powered off.
-
Do not touch exterior areas that are marked by the high temperature symbol (yellow triangle). These areas are hot while the
-
drive is in use and immediately after being powered off.
DISCHARGE TIME (40 MINUTES)
The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be
present even when the warning indicator lights are off.
Failure to wait 40 minutes after power has been removed before performing service or repair work can result in death or
serious injury.
Stop the motor.
-
Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and
-
DC-link connections to other drives.
Wait 40 minutes for the capacitors to discharge fully before performing any service or repair work.
-
Measure the voltage level to verify full discharge.
-
UNINTENDED START
When the drive is connected to the AC mains, DC supply, or load sharing, the motor may start at any time, causing risk of death,
serious injury, and equipment or property damage. The motor may start by activation of an external switch, a fieldbus
command, an input reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up software, or after a cleared
fault condition.
Press [Off] on the LCP before programming parameters.
-
Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended
-
motor start.
Check that the drive, motor, and any driven equipment are in operational readiness.
-
ROTATING SHAFTS
Contact with rotating shafts and electrical equipment can result in death or serious injury.
Ensure that only trained and qualified personnel perform installation, start-up, and maintenance.
-
Ensure that electrical work conforms to national and local electrical codes.
-
Follow the procedures in this guide.
