ECI Technology
4. ECI Technology1
Inverter modules carrying the ECI logo and the EPC mark are triple port converters (AC in, DC in, AC out). Sinusoidal output is converted from Mains or/and DC. The block diagram below gives an explicit description of the topology and operation.
The module is built around the following sub-converters · AC to DC at input · DC to DC at input · DC to AC at output
The energy can flow either from the AC source or the DC source under the control of the local DSP controller. Thanks to internal energy buffering, the output sine wave is constant and disturbance free regardless of the active source. The BOOST functionality multiples the nominal current for a period of 20 ms (max) in the event of down stream failures. The upstream breakers do not have to be oversized to prevent tripping. The overload capacity is 125% for 15 seconds. The ECI works according to True Redundant Structure (TRS) that features decentralized and independent logic, redundant communication bus and three internal levels of disconnection to isolate a module after internal failure. This functionality is included in every inverter module. Running them in parallel provides a modular system with, no single point of failure, always-conditioned output, high system efficiency and 0 ms source transfer time.
1 Information and data given in this chapter is intended to serve as an overview of the ECI Technology. Detailed features and parameters for each individual module type in the range may differ and should be referred to in the dedicated data sheet.
11 – Bravo 25 – 230 Vac – User manual – v1.0

ECI Technology
4.1 On-line Mode
DC is the primary source of supply whilst Mains (AC) works as the secondary source. Switching time between DC input and AC input is 0 ms (source transfer). The power delivered by the DC source (usually a battery, but possibly any other type of DC generator) is converted to provide regulated and transient-free power to the load. In the event of a short circuit on the load side, the boost is automatic, timely and energized for a specific duration to trip downstream protective devices.
4.2 Safe mode
Safe mode uses DC as the primary source of supply while Mains (AC) is on standby. Mains (AC) is normally disconnected through an internal inlet relay and is only connected when down stream clearance is required (boost) or if DC is unavailable. The transfer between DC and AC results in a typical transfer time of 10 ms. Typically the safe mode is used in extremely harsh environments such as railways. Under such conditions, it provides extra isolation against mains-borne disturbances.
4.3 EPC-mode
Mains input (AC) is the primary source whilst DC works as backup. The ECI is designed to operate on Mains on a permanent basis and to deliver output voltage conditioned with low THD. The output sine wave is physically independent of whether the source is AC (or) DC. If the Mains is out of tolerance or goes down, the Inverter seamlessly switches to DC and the Inverter operates in “Back-up mode” (Changeover switching time is 0 ms). As soon as the Mains returns to its valid range, the EPC mode is automatically resumed. The EPC mode offers higher efficiency (up to 96% depending on the model) without compromising the purity of the output sine wave.
Remarks: REG modules:
Inverter modules carrying the ECI logo together with the REG mark work only with DC input. Sinusoidal output is converted from DC with the module operating as a traditional inverter. EPC mode and the boost are not available with REG modules.
4.4 Mix mode & Walk-in mode
Under some circumstances the DC and AC sources can be combined. The sequence is defined by a user selectable set of parameters. Start, control and exit are fully automatic. A specific example of Mix-mode is the Walk-in mode where the transfer from DC source to AC source is ramped up within a fixed and adjustable period of time.

The manual by pass operates via manually operated switches to create a short circuit from the AC main input directly to the output AC distribution. Standard manual by-pass is “Make before Break”. When engaged or disengaged, no disturbance is transmitted to the load. When MBP is engaged, inverter modules are switched off and can be removed without impacting the load. The battery supply is not physically disconnected. After disconnecting the battery supply (by opening the battery breakers), the shelf section is safe for maintenance.
Warning: When the system is in by-pass, the load is subjected to AC main disturbances. Before engaging manual bypass, make sure the voltage difference between AC IN and AC OUT should be less than 5 Vac to limit the inrush current.
6.3 AC Distribution Unit
6.3.1 Miniature Circuit Breakers
The standard AC output distribution unit is designed with a 35 mm DIN rail, Multi Clip termination board and N/PE copper terminal bars, and built as a part of the cabinet. The Multi Clip offers unique flexibility during installation and expansion. The terminals are spring loaded and adapt contact pressure to the size of conductor. Only one cable can be inserted per spring loaded terminal. The AC distribution unit is available with 1 pole, 2 pole or 3 poles. Max current per AC DU is 200 A, max current per terminal connector is 40 A. Two adjacent terminal connectors shall be used for 63 A breakers.

9. Installation of Cabinet (A la Carte)
9.1 Unpacking the system
CE+T cabinets are always fixed on a pallet, and then packed in a wooden crate. These crates are usually delivered laying flat, horizontally. To unpack your cabinet, we recommend the following method:
1. Make sure that the crate is laying flat, with the correct side up. This side is identified by a double red arrow.
2. Remove the top cover in order to be able to identify the top and bottom sides of the cabinet. 3. Raise the crate vertically with the top side of the cabinet up. Make sure that the cabinet does not fall forward out
of the crate while you do so. 4. Remove the cabinet and its attached pallet from the crate. If you prefer to take the wooden crate apart before raising the cabinet, make sure you do not damage or dent the cabinet while doing so.
Warning: The top cover fixing bolts may NEVER be replaced with lifting eye bolts.
9.2 Module packing
When inverters are ordered together with a system, they are either delivered in the cabinet or on a separate pallet. · If you find the inverters in the cabinet: you need to remove them in order to raise the cabinet more easily, but before you do so make sure to have identified in which slot was each module. Indeed, it is important to replace each module in the same slot it was delivered in! · If the modules have been delivered separately, in carton on pallet, they will be clearly identified in order to be placed in the right slot. · It is important to place the modules in the right slot, as this will ensure that the addressing of each module in the config file corresponds to the physical slot. Without this, the system will of course function properly but you might find it difficult to identify on which modules your applying changes you would be bringing to the config file. · Also, in 3 phase systems, replacing modules configured to function in a specific phase in a slot assigned to another phase will result in the module to be un-synchronized. Your system may not start and you will have to reconfigure manually each module that was misplaced.
If you ordered modules only: · If they are meant to be used in running systems or in a not operational single phase system, you may insert them in any slot. · If they are meant to be placed in a not yet started 3 Phase system, follow these steps: Insert one module per phase. Start the system according to the start-up and commissioning procedure. Insert the remaining modules progressively.
Module packing material shall be taken apart.

55 – Bravo 25 – 230 Vac – User manual – v1.0

Manual By-Pass (MBP)

13. Manual By-Pass (MBP)

Manual By-Pass has to be operated by trained people only.
When system is in manual by-pass the load is subjected to mains voltage without active filtering. Output alarm is activated when system is in manual by-pass.
The Manual By-Pass cannot be operated remotely.
The Manual By-Pass can be integrated into the CE+T cabinet if requested at time of order. A Manual By-Pass purchased separately must comply with the instructions within section 13.2, page 56.

13.1 Pre-requisites
Commercial AC power must be present, and the inverter must be synchronized with it, before operating MBP. The upstream commercial breaker must be correctly sized to accept the overload, and if the AC is supplied by a Gen- set, the minimal required power will be twice the nominal power of the inverter.
The inverter may be overloaded during the MBP procedure, depending on voltage network and output. Inverter voltage setting: To reduce the impact of an overload, the inverter power and current will be reduced from 150% to nominal value.
The by-pass switch disconnects all AC voltage on the shelves but has no effect on the DC feeding the inverter and the remote alarm terminal.
It is requested in order to reduce the inrush current during manual by pass operation to adjust the inverter AC output voltage to the same value as AC input voltage. If the difference between AC input and AC output voltage exceed 5 Vac, there is a risk of shutdown of inverter due to high inrush current during the return to normal operation from Manual By Pass engaged.

13.2 MBP Auxiliary Connection
If manual by pass is installed in the system, then its auxiliary should be wired as per the following:
· MBP – Single rotary switch Note: The below connection is for a sub-rack system, and auxiliary (Aux) number varies depending upon the MBP switch. So it is recommended to refer the technical sheet received along with the system.
Connect Aux3 of MBP to Digital Input 01 of controller. So that the controller gets information when MBP is engaged.
Connect Aux1 and Aux2 of MBP to Remote ON/OFF terminal in the shelf where controller is installed.

Description

Min

Allows to open the AC IN inlet relay

0 – normal running in EPC mode.

1 – AC IN inlet relay is open and so the system is 0 insulated from the Mains.

This parameter can be set to 1 only if repartition is on DC (parameter 036 should be 100)

Allow to inhibit the Booster option which

generates a current of 10 In for 20ms in case of

0

short-circuit (9 In for Nova inverter).

This parameter change the attribution of the remote ON/OFF input.

If parameter is 1, then, when system is in remote 0 OFF position, output is not stopped and AC input is stopped instead.

If this parameter is 1, the module is allowed to inject power in the grid with its AC input.

0

Records the “External Clock” mode configuration

0 – no protection in: phase drift is allowed.
1 – protection in: no phase drift allowed, stops 0 the system after 1 minute.

2 – System stops immediately.

The Walk-in mode allows the inverter to come

back progressively on the AC priority source after

0

an outage. Friendly use on Genset

Defines the protection type for working on Delta load.

0 – Default setting, and no delta load protection 0

1 – The mode is active. If one output phase stops, the other phases will also stop.

When this mode is activated, the overload

capabilities are moved from default value to 330% overload in current and power for

0

maximum 900 ms.

When this mode is activated, the module is able to start without Inview S.

0

This feature allow to limit or reduce the INRUSH

DC current when the system work on battery. To

limit the current this configuration line should

limit the inrush DC current.

0

To allow for the high capability this inverter is build with extra capacitor running on 400VDC to provide the requested energy.
