2.3 Safety Precautions
W A R N I N G
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.
-
W A R N I N G
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.

W A R N I N G
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 3: Discharge Time
W A R N I N G
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.
-
W A R N I N G
EQUIPMENT HAZARD
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 manual.
-
C A U T I O N
INTERNAL FAILURE HAZARD
An internal failure in the drive can result in serious injury when the drive is not properly closed.
Ensure that all safety covers are in place and securely fastened before applying power.

3.2 Electrical Installation
3.2.1 Electrical Installation in General
All cabling must comply with national and local regulations on cable cross-sections and ambient temperature. Copper conductors
are required. 75 °C (167 °F) is recommended.

Cable dimensions ≤95 mm2.
3.2.2 IT Mains
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.
-
For IP54, 400 V, 0.75–18.5 kW (1.0–25 hp) units, open the RFI switch by removing the EMC screw inside the drive when at IT grid. The
EMC screw is shown in the the following illustration.

For IP54, 400 V, 22-90 kW (30–125 hp) units, the RFI switch can be opened in parameter 14-50 RFI Filter. Select [1] On to turn the RFI
filter on. The RFI filter ensures that the drive complies with EMC standards. Select [0] Off only when the drive is connected to IT
mains.
N O T I C E
If reinserted, use only M3x12 screw.
3.2.3 Mains and Motor Connection
3.2.3.1 Introduction
The drive is designed to operate all standard 3-phase induction motors.
•
Use a shielded/armored motor cable to comply with EMC emission specifications and connect this cable to the motor.
•
Keep the motor cable as short as possible to reduce the noise level and leakage currents.
•
Also see EMC-Correct Installation in the 3.2.5 EMC-compliant Electrical Installation.
