The options for EC-C1200-450 have certain protections and limits that affect their function. The difference
between protections and limits is that protections stop all high voltage functions of the electric device
immediately, whereas limits only limit the functions instead of stopping them.
Overcurrent and short circuit trips protect the device from overcurrent and short circuits on the AC side
of the device. First protection is a configurable software based overcurrent trip, where the trip level can
be set by the user. Second protection is a hardware based overcurrent trip with fixed trip current level of
750 A
(reaction time <15µs). In most cases, the hardware overcurrent trip protects the device also
peak
from short circuits. In case even the hardware overcurrent trip fails, the final protection is a short circuit
trip that has maximum current value of 2700 A
(self-limiting, reaction time <2µs).

Danfoss provides electric drivetrains for applications in heavy mobile work machines, marine vessels and
transportation vehicles. The drivetrains include all essential components for converting from traditional
to hybrid electric (HEV) or electric vehicle (EV) solutions. This technology saves fuel and lowers emission
and noise levels.
The electrical devices are an essential part of the electric drivetrain system. Typically they are used as a
speed and torque controller for electric motors and as a current converter, converting alternating current
(AC) from electric generator to direct current (DC) for energy storage.
The electric device is capable for supplying three-phase alternating current, powering and controlling
electric machines, for example the EM-PMI product family electric machines.
If the drivetrain system is equipped with the smart energy storage ES-SC, it can be charged by using an

Electrical connections
Before you start the electrical installation make sure that the frame of the electric device is
grounded correctly. Refer to Chapter Grounding on page 43.
Risk of electric shock when power terminal cover is open. When working with the power
connections make sure that electricity has been disconnected and the electric device has
discharged.
Use all connections when you install an electric device with +CE1 option. Using only
connections in the connection extension box can cause overheating of the electric device.
Note that +CE1 and +CG6 option combination is an exception where only connections 2 and 3
are in use and connections 7 and 8 are not.
Make sure that the electric device is correctly grounded. Do not operate the electric device
without correctly attached protective earth conductor. Obey the installation instructions and
the guidelines for component selection given in this user guide.
The grounding cable must be able to carry the maximum supply fault current which normally
will be limited by the fuses or the Miniature Circuit Breaker (MCB). Put correctly rated fuses or
MCB in the mains supply of the electrical device: obey the local legislation and
recommendations.
Obey the installation instructions and the guidelines for component selection given in this
user guide.
Make sure that the safety grounding is correct. Refer to Chapter Mechanical installation.
Generic grounding guidelines
•
Connect the ground terminal of each electric device individually to the site grounding bus bar
(through the filter if installed).
•
The grounding connections cannot loop from one electric device to another electric device, or to any
other piece of equipment, or from any other piece of equipment.
•
Ground impedance must be compliant with local industrial safety regulations.
•
The protective ground of the unit must be connected to the system ground. Ground impedance must
meet with the requirements of national and local industrial safety regulations and electrical
requirements. The condition of the grounding connections must be checked periodically.
•
Make sure that all grounding surfaces are clean and remove paint from the contact areas.
•
For detailed information, see appropriate Chapters in this user guide.
Main frame
The best grounding is achieved when the main frame of each electric device is directly connected to the
ground. If this is not possible, the electric device must be grounded at least from one of the safety
grounding points with an appropriate grounding cable. For good functional grounding use wide flat
grounding braid. Round grounding wires are adequate for safety grounding but it does not provide very
good functional grounding because of its higher impedance at high frequencies. The grounding points
are marked to the electric device.
Safety grounding points and protective earth conductor
Touch current in the protective earth conductor exceeds 3,5 mA AC and 10 mA DC.
The cross sectional area of the protective earth conductor must be at least equal to that of the
incoming supply conductor.
One of the safety grounding points must be connected to adjacent building steel (girder, joist), a floor
ground rod, or bus bar. Grounding points must comply with national and local industrial safety
regulations and/or electrical codes.
Cabling and wiring
To make sure that the electric device functions correctly and to minimize the radiated emissions, all
connected cables and wires must be EMC-shielded. Shieldings must be connected to the ground at both
ends of the cable or wire. All power connections must be secured with cable lugs and cable glands. EMCshielded cable glands are used in all Danfoss products for the power connections. Make sure that the low
voltage cable (control signal cable) shield is also grounded from the both ends.
Cable gland assembly and power line connection
Risk of electric shock when the connection box lid is not installed.
When you work with the power connections make sure that electricity has been disconnected
and the electric device has discharged. Measure the level of the remaining voltage before you
touch the power terminals.
All electrical connections must be done according to instructions. It is essential to make sure that all
terminal connections are installed properly and the and the intended application is suitable for the
product in terms of electrical requirements/characteristics.
The cable harness for electric connections needs to be terminated with cable lugs and cable glands. It is
recommended to use IP67/68 rated, 360º shielded cable glands and single core automotive rated
screened cable.
The cable gland has three functions, it works as a stress relief, it seals the connection against water and
dirt and provides appropriate EMI shielding. Advanced cable glands could achieve high EMI attenuation
over a wide frequency range.
The cable lug and cable gland must be assembled according to instructions. For correct assembly of the
cable gland, it is recommended to use a torque key with a turnkey head and a key to adapt the cable
gland. The cable lug is connected to terminal with a M8 screw. Shielding of the power cable must be
connected to the electric device body by the cable gland. Recommendations for the tightening torques
must be followed. See the manufacturer's instructions on how to install the cable glands and the cable
lugs. The following instructions may not apply to every type of connection this electric device has.
The information below describes how to assemble screened power cables to the electric device. Pflitsch
BlueGlobe-series cable glands and H+S Radox Elastomer S automotive cables are recommended.
Cable gland assembly instruction can also be found from Pflitsch gland catalogue available from https://
www.pflitsch.de.
Correct cable gland type for the cross section cables is Pflitsch blueglobe TRI bg 225ms tri.
Cable lug and cable gland assembly steps
1. Remove the small hexagonal piece from the BlueGlobe-sealing insert as shown in Figure below.
BlueGlobe-sealing
2. Cut the cable sheath at the distance A from the end of the cable, see Figure below. Pull the cut part of
the sheath partly (length B is from 10 to 15 mm) off the cable as shown in the figure. Distance A depends
of the length of the used cable lug. Measure with the cable lug that is used and cut to suitable length.
Install two layers of copper tape on the cable so that the distance B is covered. Use 3M
Copper Foil Tape 1181 or similar.
Do not remove the cable sheath completely at this point and do not cut the braid screen of
the cable.
™
Cut length of the cable sheath
3. Insert the cable to the cable gland with slight turning motion. This helps the cable go through the
spring inside the cable gland. Push the cable gland against the sheath of the cable as shown in Figure
below.
4. After the cable gland is in place remove the length A piece of the sheath and cut the braid screen
(cover) from 10 mm (distance C) from the gland bottom as shown in Figure below.
Make sure that the cable gland spring is against the cable sheath (that is protected with
copper tape) before cutting the braid screen.
Cut the braid screen
5. Cut a piece of length D of the inner sheath shown in Figure below. The length D must be equal to the
length of the cable lug body.
6. Make sure that the conducting strands of the cable are completely free of silicone and other impurities.
Place the cable inside the cable lug body, and crimp the cable lug twice in different places. See Figure
below.
Connecting cable lug
7. Cut piece of shrink tube and shrink it over the cable lug and braid screen as shown in Figure below.
This is done to keep the braid screen in place and for extra insulation.
The shrink tube must be specified for operating temperature range from -40 ºC to 150 ºC. Self
gluing shrink tube is recommended.
8. Insert the cable through the corresponding hole in the electric device frame and connect the cable lug
to the power terminal with the correct screw. Use spring washer between the cable lug and the
connection screw or nut. Do not tighten the cable lug screw at this point to ensure fitting of the cable
gland.
Make sure that there is at least 10 mm air gap between the cable lug and other metallic
structures including the braid of the cable. If the air gap is smaller, use extra insulation shrink
tube to cover the lug.
9. Screw the cable gland to the power terminals of the electric device according to instructions. Tighten
the cable gland with the specified torque.
Tighten the gable gland from the gable gland body to enclosure with torque 15 Nm. Then
tighten the cap of the gable gland according to the instructions provided by gable gland
manufacturer (recommendation Pflitsch).
10. Tighten the cable lug using the specified torque.
11. Repeat the procedure to the other cables and connections.
12. Close the power terminal cover and install the connector shield.
13. Make sure that the power cable shields are grounded properly.
Route the power cables as far from the control signal wires as possible. The minimum
separating distance is 100 mm. The crossings must be in an angle of 90º. Power cables and
control wires should be routed near the frame of the application. Make sure that all terminal
connections are tightened correctly.
If the electric device drives a motor or generator, contact Danfoss if the power cable is longer
than 15 m. For EMC-reasons, a filter might be needed.
Install the electric device by the instructions. Make sure that all the applications of the system, for
example, batteries are connected to the electric device by the instructions of this user guide and the
product specific guidelines.
Cabling
•
For the power cables, it is recommended to use Radox Elastomer S, screened automotive cable or
equivalent cable with similar specifications.
•
Cable cross section can be 35 mm2, 50 mm2, or max. 70 mm2, depending on the maximum current of
the electric device.
•
Use only EMI-shielded power cables to make sure the correct operation of the electric device and to
minimize the radiated emissions. Cable shields must be connected to the electric device ground at
both ends of the cable. All Danfoss products use EMI-shielded cable glands for power connections.
Wiring

with red). If any of these signals is not connected, the electric device will not be switched on or it will be
in the tripped state and will not work.
Low voltage signals: minimum connections needed for powering the electric device
Minimum wiring and connections
Pin Signal name Description
13 VIN_NPower supply negative
1VIN_PPower supply positive (continuous). Typically 12-24 V, see data sheets.
2POWER_ON Power supply positive (from on/off key). Typically the same voltage as VIN_P.
24 STOP_1Stop input 1. Needs to be pulled up (same range as VIN_P) for the converter to run.
Disconnecting the STOP input or pulling it low externally causes the power semiconductor
switch drivers to be disabled, which makes the converter a diode bridge. Stopping the converter
with one of the STOP inputs causes also a fault, which needs to be cleared before continuing
operation.
3STOP_2Stop input 2. Identical to stop input 1. Both need to be pulled up in order to be able to run.
A minimal wiring scheme is shown in the figure below. The main point is that the POWER_ON input is the
one that should be used to turn the electric device ON or OFF. In particular, shut-down by
disconnecting VIN_N or VIN_P may in some circumstances result in the corruption of the parameters of
the electric device or other data.
The switch (SW1) is used to turn the converter on and off. VIN_P and VIN_N are continuously connected
to the power supply. There is an internal pull-down in the POWER_ON input. Use appropriate fuse (F1) for
protection. See values and information for fuse selection from the product data sheets.
Disconnecting the power supply
Sufficient time should elapse between bringing the POWER_ON voltage down and bringing VIN_P down.
Use of the grounding pins
In addition to the aforementioned signals, there are various ground (GND) pins in the signal connector.
CAN and I/O features use separate GND pins. The difference between unisolated GND pins and VIN_N is
that VIN_N/VIN_P go through a common mode choke for the filtering of conducted
emissions. Connecting signal GND and VIN_N together effectively disables the common mode choke.
POWER_ON and STOP signals use device internal GND as their reference. If, externally, they are produced
with respect to VIN_N, a high level of common mode disturbance may throw POWER_ON and STOPs out
of their operating range and cause the converter to stop or reboot. This can be fixed by connecting
VIN_N and signal GND, but this comes at the cost of increased EMI. Finally, there is an enclosure ground
pin, which is connected to the enclosure (frame) of the converter and can be used to connect cable
shields.
General information
Connect VIN_P to the positive power supply and VIN_N to the negative power supply. POWER_ON and
STOP_1/STOP_2 are usually connected to positive power supply. If STOP signals are used connect the
emergency stop switch between the STOP and positive power supply.
STOP signal should go high at the same time or before the power supply is connected to VIN_P and
VIN_N. If STOP signals are connected after VIN_P and VIN_N the inverter will most likely register the STOP
as active and be in emergency stop trip state. If this happens the wiring can be changed connecting the
power supply to VIN_P and VIN_N at same time or before the STOP signals. The emergency state trip can
also be cleared after every startup of the electric device.
CAN-network should be done using twisted pair shielded cable to minimize EMI for the CAN signals. It is
recommended to not use the shield of the CAN cable as the CAN ground, but to use a separate ground
wire.
CAN grounding
If PT100/1000 temperature inputs are used, use signal ground as the ground connection for the sensor.
Motor overload protection
The electric device has three PT100/1000 external temperature sensor inputs that can be used to protect
the motor from overheating. These inputs can be configured to derate the motor current linearly
between two temperatures. For example derate could start when motor temperature is 130°C and
linearly derate the motor current as motor heats and the maximum derate could be at 150°C. Additionally
there are three configurable temperature levels that can cause different actions. First level is note, second
is warning and third is fault. Note can only be seen in fault log of the device. Warning can be seen as CANmessage as well as in fault log. Fault will trip the device stopping all operation and will also show as CAN
message and in fault log.
In addition to the temperature surveillance that can be used the device has over current and short circuit
protection that stops the device if short circuit or over current is detected.
Signals for monitoring, diagnostics and set-up
The electric device can be connected to the USB-port of the PC with the maintenance connector (USB to
RS485). Maintenance connector enables monitoring, diagnostics and setting up of the electric device. By
using the PowerUSER application, it enables these functions via remote access, for example in the case of
problem solving.
Reliable connection between the PC and the electric device can be ensured by using the Power Series
Service Cable (PSSC). The PSSC is isolated RS485 and shielded cable, designed for demanding
environments. The cable is available in 3 meter (PSSC-3M) and 10 meter version (PSSC-10M). Same cable
can be used with all Danfoss products that have a service connector.
The service cable is ordered separately, see Chapter Service parts on page 69 for ordering details.
PowerUSER application can be downloaded for free from http://www.danfoss.com/.
