WARNING

installation, start-up, and maintenance by qualified
personnel could result in death or serious injury.

converters contain high voltage when

Installation, start-up, and maintenance must be

•

performed by qualified personnel only.

WARNING

UNINTENDED START

the frequency converter is connected to AC mains,

When
the motor may start at any time, causing risk of death,
serious injury, equipment, or property damage. The
motor can start by means of an external switch, a serial
bus command, an input reference signal from the LCP or
LOP, or after a cleared fault condition.

1. Disconnect the frequency converter from mains
whenever personal safety considerations make
it necessary to avoid unintended motor start.

2. Press [Off/Reset] on the LCP, before
programming parameters.

3. The frequency converter, motor, and any driven
equipment must be in operational readiness
when the frequency converter is connected to
AC mains.

WARNING

DISCHARGE TIME

frequency converter contains DC-link capacitors,

The
which can remain charged even when the frequency
converter is not powered. Failure to wait the specified
time after power has been removed before performing
service or repair work, could result in death or serious
injury.

1. Stop motor.

2. Disconnect AC mains, permanent magnet type
motors, and remote DC-link power supplies,
including battery back-ups, UPS, and DC-link
connections to other frequency converters.

3. Wait for the capacitors to discharge fully, before
performing any service or repair work. The
duration of waiting time is specified in
Table 1.1.

Leakage

Follow national and local codes regarding protective
earthing of equipment with a leakage current > 3,5 mA.
frequency converter technology implies high frequency
switching at high power. This generates a leakage current
in the ground connection. A fault current in the frequency
converter at the output power terminals might contain a
DC component which can charge the filter capacitors and
cause a transient ground current. The earth leakage
current depends on various system configurations
including RFI filtering, screened motor cables, and
frequency converter power.

EN/IEC61800-5-1 (Power Drive System Product Standard)
requires special care if the leakage current exceeds 3,5 mA.
Earth grounding must be reinforced in one of the
following ways:

See EN 60364-5-54 § 543.7 for further information.

Using RCDs

Where residual current devices (RCDs), also known as earth
leakage circuit breakers (ELCBs), are used, comply with the
following:

Motor Thermal Protection

Motor overload protection is possible by setting parameter
1-90 Motor Thermal Protection to [4] ETR trip. For the North

American market: Implemented ETR function provide class
20 motor overload protection, in accordance with NEC.

Installation at High Altitudes

For altitudes above 2.000 m, contact Danfoss regarding
PELV.

Two separate ground wires both complying with

the dimensioning rules.

1. Use RCDs of type B only which are capable of
detecting AC and DC currents.

2. Use RCDs with an inrush delay to prevent faults
due to transient earth currents.

3. Dimension RCDs according to the system configu­ration and environmental considerations.

Branch circuit protection

To
all branch circuits in an installation, switch gear, machines
etc., must be short-circuited and overcurrent protected
according to national/international regulations.

Short circuit protection

Danfoss recommends using the fuses mentioned in the
following tables to protect service personnel or other
equipment in case of an internal failure in the unit or
short-circuit on DC-link. The frequency converter provides
full short circuit protection in case of a short-circuit on the
motor or brake output.

Overcurrent protection

Provide overload protection to avoid overheating of the
cables in the installation. Overcurrent protection must
always be carried out according to national regulations.
Fuses must be designed for protection in a circuit capable
of supplying a maximum of 100,000 A

(symmetrical),

rms

480 V maximum.

Non UL compliance

If UL/cUL is not to be complied with, Danfoss recommends
using the fuses mentioned in Table 1.5, which ensures
compliance with EN50178/IEC61800-5-1:
In case of malfunction, not following the fuse recommen­dation may result in damage to the frequency converter
and the installation.

1.8 General Technical Data

Protection and features

Electronic thermal motor protection against overload.

•

Temperature monitoring of the heat sink ensures that the frequency converter trips in case of overtemperature

•

The frequency converter is protected against short-circuits between motor terminals U, V, W.

•

When a motor phase is missing, the frequency converter trips and issues an alarm.

•

When a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).

•

Monitoring of the intermediate circuit voltage ensures that the frequency converter trips, when the intermediate

•

circuit voltage is too low or too high.
The frequency converter is protected against ground faults on motor terminals U, V, W.

1.9 Special Conditions

1.9.1 Derating for Ambient Temperature

The ambient temperature measured over 24 hours should

at least 5 °C lower than the max. ambient temperature.

be

If the frequency converter is operated at high ambient
temperature, the continuous output current should be
decreased.

The frequency converter has been designed for operation
at max 50 °C ambient temperature with one motor size
smaller than nominal. Continuous operation at full load at
50 °C ambient temperature will reduce the lifetime of the
frequency converter.

1.9.2 Derating for Low Air Pressure

The cooling capability of air is decreased at low air
pressure.

For altitudes above 2.000 m, contact Danfoss regarding
PELV.

Below 1.000 m altitude no de-rating is necessary, but
above 1.000 m the ambient temperature or the maximum
output current should be decreased.
Decrease the output by 1% per 100 m altitude above 1000
m or reduce the max. ambient temperature by 1 ° C per
200 m.

1.9.3 Derating for Running at Low Speeds

When a motor is connected to at frequency converter,
check

that the cooling of the motor is adequate.
A problem may occur at low speeds in constant torque
applications. Running continuously at low speeds – below
half the nominal motor speed – may require additional air
cooling. Alternatively, select a larger motor (one size up).
