2.2 Important safety information
Danger to life due to electric shock when live components or cables are
touched
• All work on the inverter must only be carried out by qualified personnel
who have read and fully understood all safety information contained in this
manual.
• Do not open the product.
• Children must be supervised to ensure that they do not play
with this device.
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage
which is present in the DC conductors and the live components of the
inverter. Touching the DC conductors or the live components can lead to
lethal electric shocks. If you disconnect the DC connectors from the
inverter under load, an electric arc may occur leading to electric shock and
burns.
• Do not touch non-insulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed and commissioned only by qualified
persons with the appropriate skills.
•If an error occurs, have it rectified by qualified persons only.
•Prior to performing any work on the inverter, disconnect it from all voltage
sources as described in this document(see Section 9 "Disconnecting the
Inverter from Voltage Sources").

Risk of injury due to electric shock
Touching an ungrounded PV module or array frame can cause a lethal
electric shock.
• connect and ground the PV modules, array frame and electrically
conductive surfaces so that there is continuous conduction.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• During operation, do not touch any parts other than the enclosure lid of
the inverter.
Damage to the inverter due to electrostatic discharge
Internal components of the inverter can be irreparably damaged by
electrostatic discharge.

9. The mounting method, location and surface must be suitable for the
inverter's weight and dimensions.
10. If mounted in a residential area, we recommend mounting the inverter on
a solid surface. Plasterboard and similar materials are not recommended
due to audible vibrations when in use.
11. Do not put any objects on the inverter.
12. Do not cover the inverter.
4.2 Selecting the mounting location
1. Mount the inverter vertically or tilted backward by a maximum of 15°.
2. Never mount the inverter tilted forward or sideways.
3. Never mount the inverter horizontally.
4. Mount the inverter at eye level to make it easy to operate and to read the
display.
5. The electrical connection area must point downwards.
Danger to life due to fire or explosion
• Do not mount the inverter on flammable construction materials.
• Do not mount the inverter in areas where flammable materials are
stored.
• Do not mount the inverter in areas where there is a risk of explosion.

UM0026_ASW5000-10000-S-A_EN_V01_0622 13
4.3 Mounting the inverter with the wall bracket
Mounting procedures:
1.Use the wall bracket as a drilling template and mark the positions of the drill
holes. Drill 2 holes with a 10 mm drill. The holes must be about 70 mm
deep. Keep the drill vertical to the wall, and hold the drill steady to avoid
tilted holes.
2.After drilling holes in the wall, place three screw anchors into the holes, then
attach the wall mounting bracket to the wall using the self-tapping screws
delivered with the inverter.
Risk of injury due to the weight of the inverter
•When mounting, be careful that the inverter weighs approx.:18.5kg.
7.5kg.
Risk of injury due to the inverter falls down
•Before inserting the wall anchors, measure the depth and distance of the
holes.
•If the measured values do not meet the hole requirements, redrill holes.

14 UM0026_ASW5000-10000-S-A_EN_V01_0622
3.Position and hang the inverter onto the wall bracket ensuring the two studs
located on the outer ribs of the inverter are slotted into the respective slots
in the wall bracket.
4.Check both sides of the heat sink to ensure that it is securely in place. insert
one screw M5x12 each into the lower screw hole on both sides of the
inverter anchorage bracket respectively and tighten them.
If a second protective conductor is required in installation site, ground the
inverter and secure it so that it cannot drop from the housing (see section
5.4.3 “Second protective grounding connection”).
Dismante the inverter in reverse order.

5 Electrical Connection
5.1 Safety
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage
which is present in the DC conductors and the live components of the
inverter. Touching the DC conductors or the live components can lead to
lethal electric shocks. If you disconnect the DC connectors from the
inverter under load, an electric arc may occur leading to electric shock
and burns.
• Do not touch non-insulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed and commissioned only by qualified
persons with the appropriate skills.
• If an error occurs, have it rectified by qualified persons only.
• Prior to performing any work on the inverter, disconnect it from all
voltage sources as described in this document(see Section 9
"Disconnecting the Inverter from Voltage Sources").
Risk of injury due to electric shock
• The inverter must be installed only by trained and authorized electricians.
• All electrical installations must be done in accordance with the National
Wiring Rules standards and all locally applicable standards and
directives.

16 UM0026_ASW5000-10000-S-A_EN_V01_0622
5.2 System layout of units without integrated DC switch
Local standards or codes may require that PV systems are fitted with an
external DC switch on the DC side. The DC switch must be able to safely
disconnect the open-circuit voltage of the PV array plus a safety reserve of
20%.
Install a DC switch to each PV string to isolate the DC side of the inverter. We
recommend the following electrical connection:

5.4.1 Conditions for the AC connection
Cable Requirements
The grid connection is established using three conductors (L, N, and PE).
We recommend the following specifications for stranded copper wire. The AC
plug housing has the lettering of length for stripping cable..

B
Conductor cross-section

C
Stripping length of the insulated conductors
approx. 16 mm
D
Stripping length of the outer sheath of cable
approx. 46 mm
Larger cross-sections should be used for longer cables.
Cable design
The conductor cross-section should be dimensioned to avoid power loss in
cables exceeding 1% of rated output power.
The higher grid impedance of the AC cable makes it easier to disconnect from
the grid due to excessive voltage at the feed-in point.
The maximum cable lengths depend on the conductor cross-section as
follows:

The required conductor cross-section depends on the inverter rating, ambient

requirements of the country of installation, etc.
Residual current protection

UM0026_ASW5000-10000-S-A_EN_V01_0622 19
The product is equipped with an integrated universal current-sensitive residual
current monitoring unit inside. The inverter will disconnect immediately from
the mains power as soon as fault current with a value exceeding the limit.
Overvoltage category
The inverter can be used in grids of overvoltage category III or lower in
accordance with IEC 60664-1. This means that it can be permanently
connected at the grid-connection point in a building. In installations involving
long outdoor cable routing, additional measures to reduce overvoltage
category IV to overvoltage category III are required.
AC circuit breaker
In PV systems with multiple inverters, protect each inverter with a separate
circuit breaker. This will prevent residual voltage being present at the
corresponding cable after disconnection.
No consumer load should be applied between AC circuit breaker and the
inverter.
The selection of the AC circuit breaker rating depends on the wiring design
(wire cross-section area), cable type, wiring method, ambient temperature,
inverter current rating, etc. Derating of the AC circuit breaker rating may be
necessary due to self-heating or if exposed to heat.
The maximum output current and the maximum output overcurrent protection
of the inverters can be found in section 10 "Technical data".
Grounding conductor monitoring
The inverter is equipped with a grounding conductor monitoring device. This
grounding conductor monitoring device detects when there is no grounding
If an external residual-current protection device is required, please install
a type B residual-current protection device with a protection limit of not
less than 100mA.
