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.
4.-Fix the new/repaired drive to the mounting bracket 4XM5/M6 (H3/H4).
Installation
Table 12: Drive Mounting Torque Details
3.2 Electrical Installation
3.2.1 Tightening Torques
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.
Table 13: Tightening Torques for Enclosure Sizes H3–H4, 3x380–480 V
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.
On IP20, 380–480 V 7.5 kW (10 hp), 11 kW (15 hp), 15 kW (20 hp) units, open the RFI switch by removing the screw on the side of the
drive when at IT grid.
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 A
(symmetrical), 480 V maximum.
rms
3.2.4.4 CE Compliance
To ensure compliance with 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 A
Remove the terminal cover to access the control terminals.
Use a flat-edged screwdriver to push down the lock lever of the terminal cover under the LCP, then remove the terminal cover as
The following illustration shows all the drive control terminals. Applying start (terminal 18), connection between terminals 12-27,
and an analog reference (terminal 53 or 54, and 55) make the drive run.

mode is set in parameter 5-03 Digital Input 29 Mode (PNP is default value).
If the motor or the equipment driven by the motor, for example, a fan, is making noise or vibrations at certain frequencies, configure
the following parameters or parameter groups to reduce or eliminate the noise or vibrations:
•
Parameter group 4-6* Speed Bypass.
•
Set parameter 14-03 Overmodulation to [0] Off.
•
Switching pattern and switching frequency parameter group 14-0* Inverter Switching.
Setup number shows the active setup and the edit setup. If the same setup acts as both active and edit setup, only that setup
number is shown (factory setting). When active and edit setup differ, both numbers are shown in the display (setup 12). The
number flashing indicates the edit setup.

the resistance Rs and Rr are increased. In most cases,
however, this is not critical.

6.3 Special Conditions
6.3.1 Derating for Ambient Temperature and Switching Frequency
Ensure that the ambient temperature measured over 24 hours is at least 5 °C (9 °F) lower than the maximum ambient temperature
that is specified for the drive. If the drive is operated at a high ambient temperature, decrease the continuous output current.

45°C (113 °F) is the refrigerant temperature.
6.3.2 Derating for Low Air Pressure and High Altitudes
The cooling capability of air is decreased at low air pressure. For altitudes above 2000 m (6562 ft), contact Danfoss regarding PELV.
Below 1000 m (3281 ft) altitude, derating is not necessary. For altitudes above 1000 m (3281 ft), decrease the ambient temperature
or the maximum output current. Decrease the output by 1% per 100 m (328 ft) altitude above 1000 m (3281 ft) or reduce the maximum ambient cooling air temperature by 1 °C (1.8 °F) per 200 m (656 ft).
6.4 General Technical Data
6.4.1 Protection and Features
•
Electronic motor thermal protection against overload.
•
Temperature monitoring of the heat sink ensures that the drive trips if there is overtemperature.
•
The drive is protected against short circuits between motor terminals U, V, W.
•
When a motor phase is missing, the drive trips and issues an alarm.
•
When a mains phase is missing, the drive trips or issues a warning (depending on the load).
•
Monitoring of the DC-link voltage ensures that the drive trips when the DC-link voltage is too low or too high.
•
The drive is protected against ground faults on motor terminals U, V, W.
6.4.2 Mains Supply (L1, L2, L3)
The unit is suitable for use on a circuit capable of delivering not more than 100000 A
