2.3 Safety Precautions
WARNING
HIGH VOLTAGE
AC drives contain high voltage when connected to AC mains input, DC supply, or load sharing. Failure to perform installation,
start-up, and maintenance by qualified personnel can result in death or serious injury.
-Only qualified personnel must perform installation, start-up, and maintenance.

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

3.2.2 IT Mains
CAUTION
IT Mains
Installation on isolated mains source, that is, IT mains.
-Ensure that the supply voltage does not exceed 440 V (3x380–480 V units) when connected to mains.
On IP20, 200–240 V, 0.25–11 kW (0.33–15 hp) and 380–480 V, IP20, 0.37–22 kW (0.5–30 hp) units, open the RFI switch by removing the
screw on the side of the drive when at IT grid.

On 400 V, 30–90 kW (40–125 hp) and 600 V units, set parameter 14-50 RFI Filter to [0] Off when operating in IT mains.
For IP54, 400 V, 0.75–18.5 kW (1–25 hp) units, the EMC screw is inside the drive, as shown in the the following illustration.

• Use a shielded/armored motor cable to comply with EMC emission specifications and connect this cable to both the decoupling
plate and the motor.
• Keep the motor cable as short as possible to reduce the noise level and leakage currents.
• For further details on mounting the decoupling plate, see VLT® HVAC Basic Drive Decoupling Plate Mounting Instruction.
• Also see EMC-Correct Installation in the 3.2.5 EMC-correct Electrical Installation.
3.2.3.2 Connecting to Mains and Motor
1. Mount the ground cables to the ground terminal.
2. Connect the motor to terminals U, V, and W, and then tighten the screws according to the torques.
3. Connect the mains supply to terminals L1, L2, and L3, and then tighten the screws according to the torques described in 3.2.1
Electrical Installation in General.
