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.

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.
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.

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.

3.2.4 Fuses and Circuit Breakers
3.2.4.1 Branch Circuit Protection
To prevent fire hazards, protect the branch circuits in an installation - switch gear, machines, and so on - against short circuits and
overcurrent. Follow national and local regulations.
3.2.4.2 Short-circuit Protection
Danfoss recommends using the fuses and circuit breakers listed in this chapter to protect service personnel or other equipment in
case of an internal failure in the unit or a short circuit on the DC link. The drive provides full short-circuit protection in case of a short
circuit on the motor.
3.2.4.3 Overcurrent Protection
Provide overload protection to avoid overheating of the cables in the installation. Overcurrent protection must always be carried
out according to local and national regulations. Design circuit breakers and fuses for protection in a circuit capable of supplying a
maximum of 100000 Arms (symmetrical), 480 V maximum.
3.2.4.4 UL/Non-UL Compliance
To ensure compliance with UL or IEC 61800-5-1, use the circuit breakers or fuses listed in this chapter. Circuit breakers must be
designed for protection in a circuit capable of supplying a maximum of 10000 Arms (symmetrical), 480 V maximum.
3.2.4.5 Recommendation of Fuses and Circuit Breakers
NOTICE
If a malfunction occurs, failure to follow the protection recommendation may result in damage to the drive.

3.2.5 EMC-compliant Electrical Installation
To ensure EMC-correct electrical installation, observe the following:
Use only shielded/armored motor cables and shielded/armored control cables.
Ground the shield at both ends.
Avoid installation with twisted shield ends (pigtails), because it reduces the shielding effect at high frequencies. Use the cable
clamps provided.
Ensure the same potential between the drive and the ground potential of PLC.
Use star washers and galvanically conductive installation plates.
