Only qualied personnel are allowed to install the
drive system.
CAUTION
POTENTIAL HAZARD IN THE EVENT OF INTERNAL FAILURE
There is a risk of personal injury when the drive modules are not properly closed.
Before applying power, ensure that all safety
covers are in place and securely fastened.
WARNING
DISCHARGE TIME
The drive module contains DC-link capacitors. Once mains power has been applied to the drive, these capacitors can remain charged even after the power has been removed. High voltage can be present even when the warning indicator lights are o. Failure to wait 20 minutes after power has been removed before performing service or repair work can result in death or serious injury.
1. Stop the motor.
2. Disconnect AC mains and remote DC-link supplies, including battery back-ups, UPS, and DC-link connections to other drives.
3. Disconnect or lock the PM motor.
4. Wait 20 minutes for the capacitors to discharge fully before performing any service or repair work.

Safety
VLT® Parallel Drive Modules
WARNING
LEAKAGE CURRENT HAZARD (>3.5 mA)
22
Leakage currents exceed 3.5 mA. Failure to ground the drive system properly can result in death or serious injury. 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 switching generates a leakage current in the ground connection. A fault current in the drive system at the output power terminals sometimes contain a DC component, which can charge the lter capacitors and cause a transient ground current. The ground leakage current depends on various system congurations including RFI ltering, shielded motor cables, and drive system power. If the leakage current exceeds 3.5 mA, EN/IEC 61800-5-1 (Power Drive System Product Standard) requires special care.
Grounding must be reinforced in 1 of the following ways:
Ensure the correct grounding of the equipment
by a certied electrical installer.
Ground wire of at least 10 mm2 (6 AWG).
Two separate ground wires, both complying
with the dimensioning rules.
See EN 60364-5-54 § 543.7 for further information.
WARNING
HEAVY LOAD
Unbalanced loads can fall and loads can tip over. Failure to take proper lifting precautions increases risk of death, serious injury, or equipment damage.
Never walk under suspended loads.
To guard against injury, wear personal
protective equipment such as gloves, safety glasses, and safety shoes.
Be sure to use lifting devices with the
appropriate weight rating. The lifting bar must be able to handle the weight of the load.
The load’s center of gravity may be in an
unexpected location. Failure to locate the center of gravity correctly, and position the load accordingly before lifting the load, can cause the unit to fall over or tilt unexpectedly during lifting and transport.
The angle from the top of the drive module to
the lifting cables has an impact on the maximum load force on the cable. This angle must be 65° or greater. Attach and dimension the lifting cables properly.
WARNING
EQUIPMENT HAZARD
Contact with rotating shafts and electrical equipment can result in death or serious injury.
Ensure that only trained and qualied personnel
perform the installation.
Ensure that electrical work conforms to national
and local electrical codes.
Follow the procedures in this document.
WARNING
DISCONNECT POWER BEFORE SERVICING
Sometimes during installation, AC mains power is applied but then must be disconnected to change the line connections. Failure to follow these steps can result in death or serious injury.
Disconnect the frequency converters from the
AC mains, 230 V supply, and motor lines.
After the lines have been disconnected, wait 20
minutes for the capacitors to discharge.

Product Overview Installation Guide
3 Product Overview
3.1 Intended Use
A frequency converter is an electronic motor controller that uses 1 or more drive modules to convert AC mains input into a variable AC waveform output. The frequency and voltage of the output are regulated to control the motor speed or torque. The frequency converter varies the motor speed based on system feedback, such as position sensors on a conveyor belt. The frequency converter also regulates the motor in response to remote commands from external controllers.
The VLT® Parallel Drive Modules basic kit described in this guide is UL 508 C compliant. The kit is used to create drive systems of 2 or 4 drive modules. These drive modules are based on the D4h frequency converter and can provide a greater power range in a smaller enclosure. The basic kit is designed to allow the exibility to either order components through Danfoss or fabricate custom components.

Mechanical Installation Installation Guide
4.2.5 Cooling and Airow Requirements
The recommendations provided in this section are necessary for eective cooling of the drive modules within the panel enclosure. Each drive module contains a heat sink fan and a mixing fan. Typical enclosure designs utilize door fans along with the drive module fans to remove waste heat from the enclosure.
Danfoss provides several back-channel cooling kits as options. These kits remove 85% of the waste heat from the enclosure, reducing the need for large door fans.
NOTICE
Make sure that the total ow of the cabinet fans meets the recommended airow.
Drive module cooling fans
The drive module is equipped with a heat sink fan, which provides the required heat sink. Also, there is a cooling fan mounted on the top of the unit, and a small 24 V DC mixing fan mounted under the input plate that operates any time the drive module is powered on.
In each drive module, the power card provides DC voltage to power the fans. The mixing fan is powered by 24 V DC from the main switch mode power supply. The heat sink fan and the top fan are powered by 48 V DC from a dedicated switch mode power supply on the power card. Each fan has a tachometer feedback to the control card to conrm that the fan is operating correctly. On/o and speed control of the fans help reduce unnecessary acoustical noise and extend the life of the fans.
Cabinet fans
When the back-channel option is not used, fans mounted in the cabinet must remove all the heat generated inside the enclosure.
For each enclosure housing 2 drive module, the cabinet fan ow recommendation is as follows:
When back-channel cooling is used, 680 m3/h (400 cfm) ow is recommended.
When back-channel cooling is not used, 4080 m3/h (2400 cfm) ow is recommended.
ow rate of 840 m3/h (500 cfm) across the

5.1 Safety Instructions
See chapter 2 Safety for general safety instructions.
WARNING
INDUCED VOLTAGE
When output motor cables from dierent frequency converters are run together, induced voltage can charge equipment capacitors even with the equipment turned o and locked out.
To avoid death or serious injury:
Run output motor cables separately or use
shielded cables.
Simultaneously lock out all the frequency
converters.
CAUTION
SHOCK HAZARD
The drive system can cause a DC current in the protective earth (PE) conductor.
When a residual current-operated protective
device (RCD) is used for protection against electrical shock, only an RCD of Type B is allowed on the supply side.
Failure to follow this recommendation could prevent the RCD from providing the intended protection.
NOTICE
MOTOR OVERLOAD PROTECTION
The drive modules are supplied with Class 20 overload protection for single motor applications.
Overcurrent protection
Extra protective equipment, such as short-circuit
protection or motor thermal protection between the drive modules and the motors, is required for applications with multiple motors.
The correct input fusing is required to acquire
approvals and meet certication requirements, and to provide short circuit and overcurrent protection. These fuses are not factory-supplied, and must be provided by the installer. See maximum fuse ratings in chapter 7.1 Power- dependent Specications.
Wire type and ratings
All wiring must comply with local and national
regulations regarding cross-section and ambient temperature requirements.
Power connection wire recommendation:
minimum 75 °C rated copper wire.
See chapter 7.6 Cable Specications for recommended wire sizes and types.

Electrical Installation
VLT® Parallel Drive Modules
5.5 Electrical Kit Installation
This section describes how the electrical kit is used to connect 2 or 4 drive modules in parallel - to provide controlled power to an AC motor. A diagram is provided for each of the 4 congurations which, if followed, meet specic agency approvals and certications. If designing and building other congurations, seek agency approvals or certications apart from Danfoss.
Read this section for guidance in making electrical connections when assembling the drive modules into a
55
panel.
5.6 DC Bus Fuse Installation
DC fuses are provided in the basic kit. Install the DC fuses at the available DC terminals at individual drive modules, using the recommended bolts. Each DC fuse has a xture for mounting the microswitches, which are used to detect a fuse failure. See Illustration 3.3. Install the supplied harness between the microswitch terminals and the brake fault jumper port on the top of the drive modules. If the jumper is not installed properly, the unit does not power up and the error Brake IGBT Fault is shown. The microswitch has 3 terminals: NO, NC, and COM. Connect the wire harness between the NC and COM terminals. If it is connected between any other terminals, the unit does not power up, and the error Brake IGBT Fault is shown.
NOTICE
The microswitch is a snap t onto the fuse. Ensure that the switch is properly installed on the fuses.
5.7 Motor Connections
5.7.1 Motor Cables
See chapter 7.6 Cable Specications for more information on wire type and sizes.
NOTICE
SHIELDED CABLE LENGTH
With a standard VLT® Parallel Drive Modules drive system, shielded cables up to 150 m (492 ft) long or unshielded up to 300 m (984 ft) long provide full voltage at the motor. If this cable length is exceeded, use a dU/dt lter. For information on the selection of a dU/dt
lter, refer to the VLT® Parallel Drive Modules Design Guide.
motor cable. Use motor cables with rated voltage speci­cation of at least 0.6/1 kV. Cables in this range provide
good resistance to insulation breakdown.
5.7.1.2 Dimensions
Follow local codes for current capacity data for cables and conductors. Widely used codes include: NFPA 70, EN 60204-1, VDE 0113-1, and VDE 0298-4. Overdimensioning for harmonics is not required.
5.7.1.3 Length
Keep cables as short as possible. Voltage drop and heat dissipation depends on the frequency and is approximately proportional to cable length. Consult the cable manufacturer specications regarding the length and expected voltage drop when connected to the drive system. See chapter 7.6 Cable Specications.
5.7.1.4 Shielding
The following factors are important for eective shielding:
Make sure that the amount of cable surface
covered by the shield is at least 80%.
Use a single-layer braided copper shield. Ensure
that the shield is braided to reduce surface area for leakage currents.
Use cables with double shielding to improve the
attenuation of interference further. Twisted conductors reduce magnetic elds.
Use cables that are shielded at both ends
between the drive system and the motor.
To comply with radio frequency interference
limits, shield the cables between the drive system and the motor at both ends.
Ensure that the shield fully surrounds the cable.
Route cable glands or cable clamps directly to
the grounding point.
Keep connections as short as possible at each
end of the cable.
Bridge shield gaps such as terminals, switches, or
contactors by using connections with the lowest possible impedance and the largest possible surface area.
NOTICE
TWISTED SHIELD ENDS (PIGTAILS)
5.7.1.1 Voltage Rating
Peak voltages up to 2.8 times the mains voltage of the
VLT® Parallel Drive Modules drive system can occur in the motor cable. High peak voltages can severely stress the
Twisted shield ends increase the shield impedance at higher frequencies, which reduces the shield eect and increases the leakage current. To avoid twisted shield ends, use integrated shield clamps. Refer to Illustration 5.2.
