WARNING
UNINTENDED START
When the drive is connected to AC mains, DC supply, or load sharing, the motor may start at any time. Unintended start during
programming, service, or repair work can result in death, serious injury, or property damage. Start the motor with an external
switch, a fieldbus command, an input reference signal from the local control panel (LCP), via remote operation using MCT 10
software, or after a cleared fault condition.
-
Disconnect the drive from the mains.
-
Press [Off/Reset] on the LCP before programming parameters.
-
Ensure that the drive is fully wired and assembled when it is connected to AC mains, DC supply, or load sharing.
WARNING
DISCHARGE TIME
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 the specified time after power has been removed before performing service or repair work could 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 for the capacitors to discharge fully. The minimum waiting time is specified in the table Discharge time and is also
visible on the nameplate on top of the drive.
-
Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors
are fully discharged.
Table 4: Discharge Time

3x200 0.25–3.7 (0.33–5) 4
3x200 5.5–11 (7–15) 15
3x400 0.37–7.5 (0.5–10) 4
3x400 11–90 (15–125) 15
3x600 2.2–7.5 (3–10) 4
3x600 11–90 (15–125) 15
WARNING
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.
