2Description


2 DescriptionConnecting the DC links of two inverters of the type MOVIDRIVE® system orMOVIDRIVE® technology is an energy-related measure to be able to use the energyflows in certain applications. The condition for this is that the application has motorand generator power requirements that can be determined cyclically.An advantage of the DC link connection can also lead to reduced installation effort fora certain connection variant, as in this case only one power supply needs to be con-nected to the largest device.If 2 inverters are connected to each another via a DC link connection, the invertersmust be additionally connected with a module bus cable. Device-internal systemstates are exchanged between the inverters via the module bus. In this case the largerinverter is the module bus master and the smaller one the module bus slave.The possible connection variants are described in the following chapters, and notesfor project planning, installation, and operation are provided.

3 Project planningNecessity of a DC link choke


3.2 Necessity of a DC link chokeThe use of a DC link choke depends on which inverters are connected and how longthe single line length of the DC link connection is.The following table lists the criteria for using a DC link choke.

INFORMATIONIf the project planning shows that DC link chokes are required, both inverters must beequipped with a DC link choke.

3 Project planningImplementing the DC link connection


3.3 Implementing the DC link connectionYou can implement the DC link connection in 2 connection types:• Connection type A: Both inverters are connected to the supply system. Inverter 1

is larger than inverter 2, or both inverters are the same size.• Connection type B: Only the larger of the two inverters is connected to the supply

system.

3.3.1 Inverters in connection type AIn connection type A, both inverters are connected to the supply system via one inputcontactor and one fuse at the supply end.To balance the rectifiers, a line choke must be connected upstream of each inverter inconnection type A.The following device combinations are permitted for connection type A:

Inverter 13 × 380 – 500 V

Line choke in-verter 1

Inverter 23 × 380 – 500 V

3.4 DC link connection and DC link fusesAs high voltages can occur in the DC link, cables with appropriate dielectric strengthmust be used, such as H07-VK. For smaller cross sections, it is advisable to usecables that are short-circuit proof.

3.4.1 DC link connectionIf the following two conditions are met, a fuse in the DC link is not required:• The DC link connection is protected by the line fuses located upstream of the in-

verter(s). Note that 1.25 times the rated current is present in the DC link. In thiscase it is advisable to use a DC link connection with the maximum permitted termi-nal cross section of the connected devices, see chapter "Technical data of basicdevice" (→ 2 35).

• With reduced cable cross section, the maximum permitted cable length from thefirst to the last unit is 3 m, the risk of short circuits is reduced to a minimum and thecable is not routed close to combustible substances.

The length of the DC link connection must be kept as short as possible.

3.4.2 DC link circuit fuses F25 to F26:The DC link circuit fuse must be configured for the line protection of the DC link con-nection. Install a fuse in each of the +UZ and -UZ lines. The fuses must be able to dis-connect the DC link voltage. Note that 1.25 times the supply system current is presentin the DC link.

CAUTIONA wiring error causes reverse polarity of the DC voltage.Before switching on the inverters, check whether the wiring of the DC link connec-tion is correct and the terminals +Uz/+Uz* and -Uz/-Uz* are assigned correctly. Incor-rectly assigned terminals can damage both inverters.

4.1 Electrical installation4.1.1 Use at IT networks

Note that operating devices with unscrewed EMC screw (IT network-capable device)and devices with inserted EMC screw (non-IT network-capable device) together is notpermitted.

4.1.2 Module bus cablingWhen connecting the DC links of two MOVIDRIVE® system orMOVIDRIVE® technology inverters in circuit type B, it is necessary to connect the twoinverters via the module bus to exchange internal device information.The inverters are connected with a module bus cable.The module bus cable is not included in the delivery of the inverter and must beordered separately. Only use module bus cables from SEW-EURODRIVE.
