3 Electrical installation
3.1 Installation in a CE typical drive system
3.1.1 General information
• The customer is responsible for maintaining the EU guidelines in the machine
operation.
– If you observe the following measures you can assume that there will be no
EMC problems caused by the regenerative power supply unit when operating
the machine and that the EU directive and the EMC law have been met.
– If you operate any devices in the vicinity of the supply and regenerative supply
unit that do not meet the CE requirements regarding interference immunity ac-
cording to EN 61000-6-2, these devices may be electromagnetically impaired
by the regenerative power supply units.
3.1.2 Structure
• Establish a connection over a large area on the grounded mounting plates for the
power supply and regenerative supply unit and radio interference suppression fil-
ter:
– Mounting plates with conductive surface (galvanized or stainless steel) make
for a permanent contact.
– Coated plates are not suitable for an EMC-compliant installation.
• If you use several mounting plates:
– Connect the mounting plates to each other over a large area (e.g. with copper
bands)
• Install the power cables and control cables separately.
• Route the cables as close as possible to the reference potential. Any free-floating
conductors act as antennas.
3.1.3 Filtering
• Use only those radio interference suppression filters assigned to the power supply
and regenerative supply units. Radio interference suppression filters reduce ex-
cessive high-frequency disturbances to a permitted level.

Addendum to the Operating Instructions – MOVIDRIVE® MDR60A1320-503-01 regenerative power supply 9
3.1.4 Shielding
• Metal cable glands ensure a connection of shield and housing over a large area.
• In case of contactors and terminals in shielded cables
– Connect the shields of all cables and connect these over a large area with the
mounting plate.
• In case of supply system cables between radio interference suppression filter and
drive controller in excess of 300mm:
– Shield supply system cable.
– Apply the shield of the supply system cable directly at the drive controller / on
the regenerative power supply unit and the radio interference suppression filter
and connect it over a large area to the mounting plate.
• SEW-EURODRIVE recommends making the cabling between the line filter and the
drive controller as short as possible and using shielded cables.
3.1.5 Grounding
• Ground all conductive metal components (power supply and regenerative supply
unit, drive controller, radio interference suppression filter) by using the appropriate
cables from a central grounding point (PE busbar).
• Comply with the minimum cross sections defined in the safety regulations:
– For EMC purposes, it is not the cable cross section but the surface of the cable
and the connection over a wide area that are important.
3.1.6 Further information
Regenerative power supply units are electrical operating resources for operation in in-
dustrial and commercial systems. These units are not subject to a specific identifica-
tion according to EMC Directive 2004/108/EC because according to EMC Directive
and EMC law, they are units intended for further installation by competent machine
and system manufacturers and cannot be operated on their own. The verification of
maintaining the protection targets required by the EMC Directive must be provided by
the installer/user of a machine/system.
When using the radio interference suppression filters provided by SEW-EURODRIVE
and adhering to the notes on EMC compliant installation, the appropriate requirements
for CE marking of the entire machine/system in which they are installed are met on the
basis of the EMC Directive 2004/108/EC.
The MOVIDRIVE® MDR60A... regenerative power supply units in combination with the
associated radio interference suppression filters are intended for operation in environ-
ments of class C2 limit.
Definition according to generic standard:
• EN 61000-6-4 for interference emission
• EN 61000-6-2 for interference immunity
3.2 Electrical connection
After you have removed the lateral knurled screws and the housing cover, the wiring
space of the MOVIDRIVE® MDR60A1320-503-01 is accessible. The incoming cables
are guided through the metal cable glands installed in the flange.

NOTICE
Make sure not to damage or tear off the cables leading to the display board
when removing the cover!
3.2.1 Power connection
Fusing:
• Consider the voltage drop in case of load when selecting the cable cross section.
• Protection of cables and regenerative power supply units on AC side (L1, L2, L3):
via commercial semiconductor fuses.
– Rated voltage of fuses must be configured according to the line voltage on site.
• Protection of the regenerative power supply on the DC voltage side at the termi-
nals + and -:
– The corresponding fuses are installed in the unit.
Connection:
• Make all connections as short and as low in inductance as possible.
• Use shielded cables to meet EMC directives (according to existing standards such
as VDE 0160 and EN 61800-5-1).
• Connect the supply cables to terminals L1, L2, and L3 of the regenerative power
supply unit. The connection must always be 3-phase.
• A certain phase sequence has to be observed for the power supply connections of
the power section (clockwise rotating field). The unit comes equipped with a phase
monitoring option. If the phase monitoring detects an incorrect phase sequence,
the unit will indicate the following fault message with its LEDs "Incorrect rotating
field" or "Phase failure" (→ chapter ""Operation and service""). In this case you
must replace 2 supply system phases of the power supply connection.
• Connect the cables for the DC link connection of the drive controller and the re-
generative power supply unit to the terminals + and -. Ensure correct polarity when
doing so!
• To absorb the torque, observe the specified torques and use a second wrench.
• Connect the protective earth conductor of the supply cable to one of the earthing
screws on the bottom of the unit.
NOTICE
Reversal or incorrect connection of the DC link cables from the + terminal or
the - terminal can destroy the drive controller and the regenerative power sup-
ply unit!

dropped to the default value.
We recommend that you block the pulse enable of the drive controller via the central-
ized alarm signal relay to prevent any problems that arise.

5.2.1 UCE disconnection
The regenerative power supply unit switches off via the UCE protective device if the
maximum current specified for the respective unit is exceeded. The operating principle
of this protective device does, however, cause an overload of the IGBTs for less than
a millisecond far in excess of its specifications for normal operation. This is not usually
a problem for the unit. If this overcurrent disconnection occurs often or regularly, the
result will be an accelerated aging of the power semiconductors and ultimately prema-
ture failure of the component.
Frequent UCE disconnections due to overcurrents can be triggered by:
• Overload
• Undervoltage in the supply system
• Defective or oscillating controller, such as in the drive controller
• An oscillating reference value of the controller
• Incorrect dimensioning of the system

4 X - - - X - Just like fault code 3.
→Heat sink temperature has
dropped and fault can be con-
firmed.
5 X - - - X Unit has been turned off (external OFF).
→Enable signal required
6 X - - - X Triggering the overvoltage monitoring.
Enable signal is required if the line voltage has dropped to
nominal value
7 X X - - X Incorrect rotating field or
phase
Phase failure has been de-
tected
→Confirmation necessary.
8 X - X - X - Overcurrent (three-phase
side) has been detected.
→Confirmation necessary.
9 X X X - X Fault codes 7 and 8 Overcurrent has been detect-
ed with simultaneous phase
failure detection due to com-
mutation notch.
10 X X X X X Several faults occurring at the same time.
11 - - - - - Unit not operating, at least 2 phases without voltage.
13 X X - - - - Massive commutation notch
has been detected, no dis-
connection because jumpers
3 and 7 are open.
→Operation can be re-
sumed, recommendation for
improved supply system.
