If stable voltages can be measured, there is a ground fault in the DC generator or its wiring. The ratio between the measured voltages gives an indication as to the location of this fault.

2.Rectify any faults before taking further measurements.

3.Determine the electrical resistance between the

–– protective earth (PE) and the positive lead of the PV generator,

–– protective earth (PE) and the negative lead of the PV generator.

Low resistance (< 2 MΩ) indicates a high-ohm ground fault of the DC generator.

4.Rectify any faults before connecting the DC generator.

Connecting the cables

DANGER

Lethal voltages in the PV system

Lethal voltages are present in the PV system.

›› Make absolutely sure that the plus and minus poles are properly insulated.

Each cable corresponds to a specific pole.

1.Connect the cables to the poles.

Make sure the polarity is correct (Figure 12):

–– Left side (item 1): Positive (DC+)

–– Right side (item 2): Negative (DC–)

2.Screw down the cables.

3.Make sure that all of the cables and seals are securely attached.

NOTE

If positive or negative grounding of the PV generator is necessary, the use of an optional grounding kit for the XP inverters is mandatory.

›› Do not ground the inverter without the grounding kit.

7.5Connecting the power supply

Without auxiliary power, the inverter is not able to start up and supply the necessary power to the MMI, the fans, measurement equipment, etc. The inverter offers two ways to supply the necessary power:

•Internal power supply (see section 7.5.1 on page 23)

•External power supply (see section 7.5.2 on page 24)

CAUTION

Internal short circuit by incorrect connection

›› Do not use the external and the internal power supply at the same time.

NOTE

In delivery status, the inverter is set for using the external power supply.

For the power consumption of the inverter see section 6.2 on page 16

7.5.1Connecting the internal power supply

NOTE

The use of internal power is subject to the following restrictions:

• The inverter can not be operated when no PV power is present.

• The inverter is not able to fulfil any communication tasks without power supply.

•Software updates or external access to the inverter is not possible without power supply.

•The use of internal power reduces the feed-in power and this finally reduces the yield of the PV plant.

No additional terminal connections have to be made for using the internal power supply.

1.Make sure that the circuit breaker CB33 (1) is switched off.

2.Secure the circuit breaker CB33 with the lock clip (2).

7.5.2Connecting the external power supply

In the standard setting, the inverter is meant to be used with external power supply.

1.Make sure that the circuit breaker CB37 (1) is switched off.

2.Secure the circuit breaker CB37 with the lock clip (2).

NOTE

Cables with a cross-section up to 2.5 mm² may be used for the connection of the external power supply.

Depending on the selected cable cross-section, choose an appropriate protection device (e.g. a C16A circuit breaker is recommended for a 1.5 mm² cross-section).

Connecting the external power supply (Figure 15)

The connection for the external power supply is located in the left inverter cabinet.

"" Connect the external power supply to the terminals marked “TO” using single-phase 230 V.
