equipment. They also tell you how to prevent the danger.

The manual uses these warning symbols:

Electricity warning – Electrical hazards which can cause injury or death, or

damage to the equipment.

General warning – Conditions, other than those caused by electricity, which

can cause injury or death, or damage to the equipment.

Electrostatic sensitive devices warning – Risk of electrostatic discharge

which can cause damage to the equipment.

Hearing loss warning – Risk of hearing loss due to high volumes. Use hearing

protection.

10 Safety instructions

Installation and maintenance safety

 Electrical safety

These warnings are for all personnel who do work on the inverter, its input and output

cables, the transformer or photovoltaic generator.

WARNING! Obey these instructions to prevent injury or death, or damage to the

equipment.

• If you are not a qualified electrician, do not do electrical installation or

maintenance work.

• Obey all installation safety standards. This can require, among other things, the use of

personal protection equipment (PPE), such as arc-proof clothing, arc-proof masks,

protective footwear, protective gloves, eye protection and hearing protection. High

power inverter installations have high fault currents. Select appropriate arc-proof

clothing (for example, in the US, a rating of 40 cal/cm

2

is required, EN531).

• Standard IEC/EN 62109-2 (section 4.8.3.6) requires that, as the inverter is not

provided with full protection against shock hazard on the photovoltaic array, you install

and use the inverter in a closed electrical operating area. There is no RCD protection

inside the inverter.

• Do not do work on the photovoltaic generator, or the inverter or its input or output

cables when the inverter is connected to an electrical power system or to the

photovoltaic generator.

• Before you do work in the inverter cabinet, isolate the AC line cables and busbars from

the electrical power system with the disconnector of the power system transformer.

Also, isolate the inverter from the photovoltaic generator with the safety switch of the

generator or by other means. The optional AC disconnectors or optional breakers do

not isolate the AC output cables and terminals of the inverter from the electrical power

system. The DC disconnectors do not isolate the DC input fuses, cables or terminals

from the DC voltage supplied by the photovoltaic generator.

• Before you do work in the inverter cabinet, set to off or isolate the auxiliary voltage

supply from the inverter.

• The inverter auxiliary power can be supplied from an external source (standard) or

from internal auxiliary power transformers. Make sure that also auxiliary power is

disconnected.

• Do not operate the inverter with the doors open, even in fault tracking conditions. The

inverter doors act as arc hazard protection. If a highly unlikely arc flash incident

happens when the inverter doors are open, even the arc-flash proof protection

equipment might not provide sufficient protection.

• Before you do work on the inverter, apply a temporary grounding for work (AC and DC

side).

• Do not work on the control cables when power is applied to the inverter or to the

external control circuits. Externally supplied control circuits can cause dangerous

voltages in the inverter even when the main power on the inverter is off.

• Live parts in the inverter cabinet are protected against direct contact when all

protective plastic covers and metallic shrouds are in place.

• Do not do insulation or voltage withstand tests on the inverter or inverter modules.

• With the grounding options selected, one of the poles of the photovoltaic generator is

grounded, and therefore, the other pole has full voltage against ground (up to 1000 V).

Safety instructions 11

• When the photovoltaic generator cells are exposed to light (even if it is dim), the

generator supplies DC voltage to the inverter.

Grounding

These instructions are for all personnel who are responsible for the grounding of the

inverter.

WARNING! Obey these instructions to prevent injury or death, damage to the

equipment and electromagnetic interference.

• If you are not a qualified electrician, do not do grounding work.

• Always ground the inverter and adjoining equipment with proper PPE on. This is

necessary for personnel safety. Correct grounding decreases electromagnetic

emissions and interference. Follow the site’s policy on disconnecting the inverter from

AC.

• The minimum cross section of the grounding conductor must be at least half of the

cross section of the line conductor or fulfill the local regulations. The grounding

conductor must withstand 50 kA RMS prospective for time duration of 1 second. Refer

to standard IEC 60364-5-54.

• In a multiple-inverter installation, connect each inverter separately to the protective

earth (PE) busbar of the switch board or the transformer.

• Avoid grounding loops and keep grounding cables at least 0.5 m away from the AC

cables, as current can be generated to a grounding loop by the electromagnetic

coupling from the supply cables.

• When you use shielded AC power cables, do a 360° high-frequency grounding of the

cable entries at the cabinet lead-through to decrease electromagnetic interference.

Connect the cable shields to the protective earth (PE) to meet safety regulations.

• External EMC filters are not permitted at the AC output of the inverter.

• Do not install the inverter on a TN (grounded) system.

Note:

• You can use power cable shields as grounding conductors only if their conductivity is

sufficient.

• As the normal touch current of the inverter can be more than 3.5 mA AC or 10 mA DC,

use a fixed protective earth connection. Refer to standard IEC/EN 62109, 5.2.5. or

IEC62477-1, 4.4.4.3.3.

Electric welding

WARNING! Do not fasten the cabinet by electric welding. ABB does not assume

any liability for damages caused by electric welding as the welding circuit can

damage electronic circuits in the cabinet.

12 Safety instructions

 Performing electrical work

These precautions are for all personnel who do work on the inverter, its input and output

cables, the transformer or the photovoltaic generator system.

WARNING! Obey these instructions to prevent injury or death, or damage to the

equipment. You must be a qualified electrician to do installation and service work.

Do these steps before you do installation or maintenance work on the inverter

1. Clearly identify the work location. Make sure that there is an escape route available in

case of an emergency.

2. Disconnect and isolate. (Not all disconnectors provide sufficient isolation against

voltage surges.)

• Disconnect the inverter from the AC supply (normally a disconnector or a breaker

on the HV side of the main transformer), because the AC disconnector or breaker

of the converter does not remove the voltage from the AC output busbars of the

inverter.

• Disconnect the inverter from the DC power supply (usually the DC circuit breakers

of the solar array junction boxes or the DC combiner box) because the optional

DC disconnectors do not remove the voltage from the inverter input DC busbars or

fuses.

• Open the AC main disconnection devices (AC breaker or AC switch disconnector)

of the inverter (Q2), the DC disconnector of the inverter (Q1), the auxiliary power

disconnectors of all the power sections (Q10), the optional 3-phase output switch

(F13). If the inverter is supplied from an external auxiliary power, disconnect also

that. For auxiliary power switches, note the following disconnection order:

a. Internal power supply (auxiliary power from main circuit) - open Q30

b. External power supply 400 VAC - open Q10 (auxiliary power circuit) - open Q30

(BAMU)

c. External power supply, not 400 VAC - open F12 (auxiliary power supply) - open

Q30 (BAMU).

• Make sure that reconnection is not possible. Lock all of the disconnectors in the

open position and attach a warning notice to them.

• After you disconnect the inverter, wait for at least 5 minutes to let the intermediate

circuit capacitors discharge before you continue.

3. Protect any other energized parts in the work location against contact.

4. Take special precautions when you do work near bare conductors.

5. Measure that the installation is not energized.

• Make sure that the voltage measurement device works correctly by testing the

measurement device with a live voltage.

• Use a voltage measurement device such as a multimeter with an impedance of at

least 1 M and voltage measurement range up to 1000 V DC.

• Make sure that the voltage between the inverter AC output terminals (L1, L2, L3)

and the grounding (PE) busbar is close to 0 V.

• Make sure that the voltage between the inverter module UDC+ and UDC-

terminals and the grounding (PE) busbar is close to 0 V.

• Make sure that the voltage between the DC input terminals DC+ and DC- and the

grounding (PE) busbar is close to 0 V.

6. Install temporary grounding as required by the local regulations. Connect the AC and

DC busbars (in both DC sections) to the PE with a temporary grounding tool.

Temporary grounding cables must be dimensioned to withstand the prospective

current of the system for time duration until upstream protection device clears the fault

current. The temporary grounding cables should be tied tightly to the busbars or the

frame of the converter as the forces of the short circuit current can cause the

temporary grounding cables to move hazardously.

7. Ask the person in control of the electrical installation work for a permit to work.

8. After you finish the work, make sure that the inverter is clean from inside and that all

the tools have been removed from inside the inverter, remove the temporary

grounding and tell the person responsible for work about the completed works. After

you make sure that the voltage can be connected, close all the doors of the inverter,

and close the disconnectors. When connecting voltage back on, do not stand right

next to the inverter. Also make sure that there is an escape route available in case of

an emergency.

14 Safety instructions

 General safety

These instructions are for all personnel who install the inverter and do maintenance work

on it.

WARNING! Obey these instructions to prevent injury or death, or damage to the

equipment.

• Move the inverter power module carefully:

• Use safety shoes with a metal toe cap and protective gloves.

• Use caution when you move an inverter power module. Do not tilt the module. The

module is heavy. It can topple over if you handle it carelessly.

• Obey the instructions in the PVS800-57B central inverters commissioning and

maintenance manual (3AXD50000048331 [EN]).

• Be aware of hot surfaces. Some parts in the inverter cabinet, such as the heat

exchangers are hot after you disconnect the electrical supply.

• Make sure that the debris from the installation work does not go into the inverter

Electrically conductive debris in the unit can cause damage.

Printed circuit boards

WARNING! Use a grounding wristband when you handle the printed circuit

boards. Do not touch the boards unnecessarily. The boards have components

that are sensitive to electrostatic discharge.

Fiber optic cables

WARNING! Obey these instructions to prevent injury or death, or damage to the

equipment.

• Handle the fiber optic cables with care.

• When you disconnect the cables, hold the connector, not the cable.

• Do not touch the ends of the fibers with bare hands as the ends are extremely

sensitive to dirt.

• Do not bend the fiber optic cables too tightly. The minimum permitted bend

radius is 35 mm (1.4 in.).

Safety instructions 15

Safe start-up and operation

These warnings are for all personnel who commission, plan the operation or operate the

inverterconverter.

WARNING! Obey these instructions to prevent injury or death, or damage to the

equipment.

• Keep all doors of the inverter closed when it operates.

• Connect the medium voltage grid to the main transformer.

• Before you start the inverter, close the AC and DC disconnectors (if present), and the

internal auxiliary transformer fuse switch F10.

• AC Q2 and DC Q1. Note the point on page 12 about auxiliary power supply.

• When the inverter operates, do not open the AC or DC disconnectors.

• Before you adjust the inverter and put it into service, make sure that all of the

equipment is suitable for operation.

• The maximum allowed number of power-ups by applying power is five in ten minutes.

• Do not use the inverter in a manner not specified in this manual.

Note:

• If the Start switch is in the ON position, the Inverter enable signal is active, and the

Start command is active, the inverterconverter starts immediately after a fault reset.
