Electrical Safety


• Electrical equipment must be installed, operated, serviced, and maintainedonly by qualified personnel.

• The active harmonic filter must be installed in a room with restricted access(qualified personnel only).

• Apply appropriate personal protective equipment (PPE) and follow safeelectrical work practices.

• Turn off all power supplying the active harmonic filter before working on orinside the equipment.

• Before working on the active harmonic filter, check for hazardous voltagebetween all terminals including the protective earth.

• The active harmonic filter contains an internal energy source. Hazardousvoltage can be present even when disconnected from the utility/mains supply.Before installing or servicing the active harmonic filter, ensure that the unitsare OFF and that utility/mains and batteries are disconnected. Wait fiveminutes before opening the active harmonic filter to allow the capacitors todischarge.

• A disconnection device (e.g. disconnection circuit breaker or switch) must beinstalled to enable isolation of the active harmonic filter from upstream powersources in accordance with local regulations. This disconnection device mustbe easily accessible and visible.

• The active harmonic filter must be properly earthed/grounded and due to ahigh leakage current, the earthing/grounding conductor must be connectedfirst.

Isolate all interconnection active harmonic filters before installation and service.


NOTE: The position of the sensors depends on the installation.

NOTE: The active harmonic filter is connected in parallel with the load.

NOTE: The active harmonic filter will be fed from a separate outgoing feeder. Thisline must be protected by a circuit breaker. The active harmonic filter uses this lineto send harmonics destined to compensate the load harmonics back onto themains.

• It is possible to connect two, three or four active harmonic filters with the samerating in parallel to compensate higher loads.

• Each active harmonic filter independently uses current measurements fromthree sensors, regardless of the state of the other active harmonic filter.

• Two cables between the active harmonic filters allow monitoring of allconnected active harmonic filters to determine the share of harmonics to besupplied.

• Each power circuit remains independent and has its own protection.

De-energize the active harmonic filter before carrying out this procedure.



Connect the PE or PEN protective conductor first.



Use adequate insulation sleeves on the power connection lugs to avoid any riskof electrical shock. Refer to IEC 60364-4-41.


NOTE: AccuSine SWP active harmonic filter is suitable for all types of earthingsystems except IT.

1. Check that the active harmonic filter supply circuit breaker placed in your lowvoltage distribution panel is in the open position (O).

2. Remove the front and lower protection plates on the active harmonic filter toaccess the connection terminal block.

3. Fit the lower protection plate of the power terminal block with bushings for cablefeedthrough. If several holes are made to feed the cables through, cut a slotcommon to all the holes to prevent eddy currents from being generated.

4. Connect the PE or PEN conductor on the bolted terminal block.

5. Connect the power cables (L1, L2, and L3) to the terminal block. Ensure correctphase rotation.

NOTE: Fasten the cables near the terminal block to prevent mechanical stresson the conductors.

NOTE: If the cables are pulled, the PE or PEN connection should be the last tobe subjected to the applied force.

Modbus & JBUS Communication System

OverviewNOTE: The communication link can be plugged into the Sub-D connector withoutshutting down the active harmonic filter.

This interface complies with safe extra low voltage insulating requirements

A. Female 9 pin SUB-D connector for connection in EIA RS485 communicationstandard

A

FunctionThe communication system, supported by a data link to the EIA RS485 standard,allows transmission to a computer tool of a set of information concerning theoperating status of the active harmonic filter. The communication protocol used iscompatible with both JBUS and MODBUS standards. The terms JBUS andMODBUS in this document can therefore be used interchangeably.

NOTE: The parameter addresses are given as “@JBUS Hexa” and they areequivalent to MODBUS addresses in IEC61131 syntax “%MW Hexa” with 0–basedindexes.

RS485 InterfaceFor proper operation, the polarity of EIA RS485 2–wire and 4–wire lines must beset at only one point and the lines terminated at the end. This principle is illustratedin RS485 Topology of 2–Wire Inter-Enclosure Link, page 41 and RS485 Topologyof 4–Wire Inter-Enclosure Link, page 42.

Polarization

Usage and logic require the master device of the network to polarize the line (Rpresistances).

Matching

Matching (Ra resistances) must be performed at both ends of the line. Toavoid non-matching of the line when disconnecting an end device you shouldprovide one or two matching caps.

Active harmonic filter is a slave device. However, its RS485 link interface can bepolarized and matched in all the chosen connection topologies either via anexternal connector or via micro switches on the active harmonic filter MERY board.

Choose the Connecting Cable

Choice of a cable depends on the relevant sector of application and on theflowrates and the environment in question. The following transmission cables canbe chosen:

Industrialsector • One, two or three conductor pairs per cable

• Shielding per conductor pair

• Multi-strand conductors

• Telephone shielded twisted pairs may be used

Tertiarysector • One, two or three conductor pairs per cable

• Cable shielding if required

• Shielded or unshielded telephone pairs may be used

Domestic• One or two conductor pairs per cable

• Telephone pairs may be used

Protection

All the shieldings are earthed on either side.

Polarization and/or Termination via the External Connector

The polarity and/or termination must be handled via jumpers in the connectioncable’s male connector.

NOTE: Polarization can be performed on reception or transmission only.
