WARNING
DISCHARGE TIME
The drive contains DC-link capacitors and, if input lter options are present, extra capacitors and inductors. These components
can remain charged even when the drive is not powered. High voltage can be present even when the warning indicator lights are
o.
Failure to wait the specied 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 specied both in the Discharge Time table and 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 2: Discharge Time

WARNING
HIGH VOLTAGE
AC drives contain high voltage when connected to AC mains input. Failure to perform installation , start-up, and maintenance by
qualied personnel can result in death or serious injury.
Only qualied personnel must perform installation, start-up, and maintenance.
WARNING
UNINTENDED START
When the drive is connected to the AC mains, DC supply, or load sharing, the motor may start at any time, causing risk of death,
serious injury, and equipment or property damage. The motor may start by activation of an external switch, a eldbus command,
an input reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up software, or after a cleared fault condi-
tion.
Press [O] on the LCP before programming parameters.
Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended motor
start.
Check that the drive, motor, and any driven equipment are in operational readiness.
WARNING
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 certied electrical installer.

WARNING
ROTATING SHAFTS
Contact with rotating shafts and electrical equipment can result in death or serious injury.
Ensure that only trained and qualied personnel perform installation, start-up, and maintenance.
Ensure that electrical work conforms to national and local electrical codes.
Follow the procedures in this guide.
CAUTION
HOT SURFACES
The drive contains metal components that are still hot even after the drive has been powered o. Failure to observe the high
temperature symbol (yellow triangle) on the drive can result in serious burns.
Be aware that internal components, such as busbars, may be extremely hot even after the drive has been powered o.
Do not touch exterior areas that are marked by the high temperature symbol (yellow triangle). These areas are hot while the
drive is in use and immediately after being powered o.
CAUTION
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 Product Overview
3.1 Intended Use
NOTICE
OUTPUT FREQUENCY LIMIT
Due to export control regulations, the output frequency of the drive is limited to 590 Hz. For demands exceeding 590 Hz, contact
Danfoss.
The enclosed drive is an electronic motor controller that converts AC mains input into a variable AC waveform output. The frequen-
cy and voltage of the output are regulated to control the motor speed or torque. Depending on the conguration, the drive can be
used in standalone applications or form part of a larger system or installation. The enclosed drive is designed to:
Regulate motor speed in response to system feedback or remote commands from external controllers.
Provide motor overload protection.
Monitor system and motor status.
Reduce harmonics and increase the power factor using the optional passive harmonic lter or line reactor.
Reduce motor acoustic noise and protect motor insulation with the optional output lters.
Reduce bearing current and shaft voltage with the optional common-mode lter.
Reduce high-frequency, electromagnetic noise in the motor cables with the optional dU/dt lter.
Provide sinusoidal output with optional sine-wave lter.
The enclosed drive is designed for residential, industrial, and commercial environments in accordance with local laws and standards.
Do not use this drive in applications that are non-compliant with specied operating conditions and environments.
NOTICE
RADIO INTERFERENCE
In a residential environment, this product can cause radio interference.
Take supplementary mitigation measures.
3.2 What is an Enclosed Drive?
The enclosed drive is an IP21/54 (NEMA 1/12) enclosure surrounding an IP20 (Protected Chassis) drive to form the basis of the sys-
tem. There are 4 enclosed drive models with varying power ratings.
D9h model: 110–160 kW (125–250 hp)
D10h model: 200–400 kW (250–450 hp)
E5h model: 355–630 kW (450–650 hp)
E6h model: 500–800 kW (650–950 hp)
The enclosed drive is available with various power options and input and output lters to create a factory-built, custom drive. Some
options and lters result in extra cabinets attached to the left or right side of the drive cabinet. These optional cabinets are shown
with dotted lines, while the drive cabinet is shaded.

3.4.1 Identifying the Drive and Its Options
Enclosure size and specic options are used throughout this guide whenever procedures or components dier based on the drive
and its options. Use the following steps to identify the enclosed drive:
Procedure
Locate the type code (T/C) on the nameplate. The nameplate is found on the exterior of the drive by the bottom grill and
on the control compartment door.
Determine the type of enclosure by obtaining the following information from the type code:
Product group and drive series (characters 1–6).
Voltage rating (character 8).
Model/power rating (characters 10–12).
