1. Safety and Conformity

1.1. Safety Information

All persons installing and servicing inverters must be:

• Trained and experienced in general safety rules for work on electrical equipment

• Familiar with local requirements, rules and regulations for the installation

Safety information important for human safety. Violation of warnings may result in

injury to persons or death.

Information important for the protection of property. Violation of this type of in-

formation may cause damage and loss of property.

Note:

Useful additional information or “Tips and Tricks” on specific subjects.

Read this before installing, operating or maintaining the inverter.

1. Safety and Conformity

2 8000038781_00_BAL_en / L00410564-01_02

Before installation:

Check for damage to inverter and packaging. If in doubt, contact the supplier be-

fore installing the inverter.

Installation:

For optimum safety, follow the steps described in this manual. Keep in mind that

the inverter has two voltage carrying sides; the PV input and the AC grid.

Disconnecting the inverter:

Before starting work on the inverter, switch off AC grid at the mains switch and PV

using the PV load switch. Ensure that the device cannot be unintentionally recon-

nected. Use a voltage tester to ensure that the unit is disconnected and voltage

free. The inverter can still be charged with very high voltage at hazardous levels

even when it is disconnected from grid/mains and solar modules. Wait at least 30

min. following disconnection from grid and PV panels before proceeding.

Maintenance and modification:

Only authorised personnel are allowed to repair or modify the inverter. To ensure

optimum personal safety, only original spare parts available from the supplier

should be used. If non-original spare parts are used, the compliance with CE

guidelines in respect of electrical safety, EMC and machine safety is not guaran-

teed.

Also observe the danger of burn injury. The temperature of the cooling racks and

components inside the inverter may exceed 70ºC.

Functional safety parameters:

Never change the parameters of the inverter without authorisation from the local

energy supply company and instructions from AEG PS.

Unauthorised changes of functional safety parameters may cause injury or acci-

dents to people or inverter. Additionally it will lead to the cancellation of all inver-

ter operating approval certificates.

The AEG PS inverters are all designed according to the German VDE0126-1-1

(February 2006) standard, which includes an insulation test between PV array(s)

and Earth, and a type B, RCMU according to DIN VDE 0100-712.

1.2.

Hazards of PV Systems

Very high DC voltages are present in the system even when the AC grid is disconnected. Faults

or inappropriate use may lead to electric arcing. Do not work on the inverter while it has cur-

rent connected to it.

The short-circuit current of the photovoltaic panels is only slightly higher than the maximum op-

erating current and depends on the level of solar irradiation.

1.3.

PV Load Switch

For safety, check all wiring. Connecting a phase wire to the neutral terminal may

permanently damage the inverter. Do not remove the short circuit bridge at (1).

3.6. PV Connection

Note:

When choosing the installation place, ensure that all labels are visible at all times.

For details refer to the section

Specifications

Do NOT connect PV to earth!

Use a suitable voltmeter that can measure up to 1000 V DC.

1. First verify the polarity and maximum voltage of the PV arrays by measuring the PV

open circuit voltage.The PV open circuit voltage must not exceed 1000 V DC.

2. Measure the DC voltage between the plus-terminal of the PV array and Earth (or the

green/yellow PE cable). The voltage measured should approximate zero. If the voltage

is constant and not zero there is an insulation failure somewhere in the PV array.

3. Locate and fix the failure before continuing.

4. Repeat this procedure for all arrays. It is allowed to distribute the input power on the

inputs unevenly, presuming that:

• The nom. PV power of the inverter is not exceeded (10.3 / 12.9 / 15.5 kW).

• The individual input is not exceedingly loaded, and not more than 6000 W.

• The maximum short circuit current of the PV modules at STC (Standard Test

Conditions) must not exceed 12 A per input.

Illustration 3.13: DC Connection Area

On the inverter turn the PV load switch into

off position. Connect the PV cables by means

of MC4 connectors. Ensure correct polarity!

The PV load switch can now be switched on

when required.

3. Installation

16 8000038781_00_BAL_en / L00410564-01_02

When unmated the MC4 connectors are not IP54. The intrusion of moisture may

occur in the following situations:

1. The inverter runs in Master/Slave operation and only one or two PV in-

puts are in use. In this case, the other inputs are not connected to PV

and they are therefore open to intrusion.

2. Not all PV inputs are connected.

3. PV connectors are not fitted; for example in case of disconnection of

parts of a PV plant over a longer period of time.

In situations where the PV connectors are not fitted, a seal cap must be mounted

(included in the scope of the delivery). All inverters with MC4 connections are de-

livered with seal caps on inputs 2 and 3. During installation, the seal caps of those

inputs that are to be used are discarded.

Note:

The inverter is protected against reversed polarity but it will not generate power until the po-

larity is corrected. To achieve optimum production, the open circuit voltage (STC) of the PV

modules must be lower than the max. input voltage of the inverter (see the specifications),

multiplied with a factor of 1.13. U

1) Max. number of inverters are 100. If GSM modem is used for portal upload, the amount of inverters in a

network is limited to 50.

2) For outdoor use, we recommend outdoor burial type cable (if buried in the ground) for both Ethernet

and RS485.

3) Third input is used for compensation of the irradiation sensor.

4) The number of inverters to be connected in the RS485 network depend on which peripheral device is

connected.

To ensure fulfilment of IP enclosure rating, correctly mounted cable glands are es-

sential for all peripheral cables.

To ensure EMC compliance, shielded cables must be applied for Sensor inputs and

RS485 communication. Unshielded cables may be applied for alarm outputs.

Other auxiliary cables must pass through the designated EMC cable clamps to es-

tablish mechanical fixing and in case of shielded cable termination to the shielding

device.

Table 5.10: RJ45 Pinout Detail

Note:

The RS485 communication bus must be terminated at both cable ends.

Note:

The two network types cannot be mixed. The inverters can only be connected in networks

which are either solely RS485 or solely Ethernet.

Note:

Each inverter has a unique RS485 address when it is delivered. This address is defined at the

time of production.

Note:

Ethernet connection is recommended for faster communication.

RS485 connection is required when a web logger or data logger is connected to the inverter.
