the following Zeversolar inverters: Zeverlution 1000S, Zeverlution 1500S, Zeverlution
2000S, Zeverlution 3000S.
Observe all documentation that accompanies the inverter. Keep them in a convenient
place and available at all times.
1.2 Target group
This manual is for qualified electricians only, who must perform the tasks exactly
as described.

2 Safety
2.1 Intended use
1. Zeverlution converts the direct current from PV array into grid-compliant
alternating current.
2. Zeverlution is suitable for indoor and outdoor use.
3. Zeverlution must only be operated with PV arrays (PV modules and cabling) of
protection class II, in accordance with IEC 61730, application class A. Do not
connect any sources of energy other than PV modules to the inverter.
4. PV modules with a high capacitance to ground must only be used if their coupling
capacitance does not exceed 1.0μF.
5. When the PV modules are exposed to sunlight, a DC voltage is supplied to this
equipment.
6. When designing the PV system, ensure that the values comply with the permitted
operating range of all components at all times. The free design program
‛Zeverplan“(http://www.zeverplan.com ) will assist you.
2.2 Safety standards
Zeverlution inverters comply with the EU Low-Voltage Directive 2006/95/EC and the
EMC Directive 2004/108/EC. Zeverlution also complies with the requirement for
safety and EMC in Australia and New Zealand market. They are labeled with the CE
mark and RCM mark.

Installation and Operating Instructions V03 7
2.3 Important safety information
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").
• 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.
• Children must be supervised to ensure that they do not play with this
device

8 Installation and Operating Instructions V03
Grounding the PV array
• Comply with local regulations for grounding the PV array. We
suggest the frames of PV modules must be reliably grounded.
•Do not ground any of the terminals of the strings.
Possible damage to health as a result of the effects of
electromagnetic radiation
• Please maintain a distance of at least 20cm from the inverter when it
is in operation.
Risk of injury due to hot heat sink
• The heat sink may get hot during operation. Do not touch!
Risk of injury due to electric shock and fire caused by high leakage
current
• The inverter must be reliably grounded in order to protect property
and personal safety.

Installation and Operating Instructions V03 9
Damage to the inverter due to electrostatic discharge
•Touching electronic components can cause damage to or destroy the
inverter through electrostatic discharge.
• Ground yourself before touching any component.
Damage to the seal of the cover in sub-zero conditions
•If you open the cover in sub-zero condition,the sealing of the cover
can be damaged.This can lead moisture entering the inverter.
• Do not open the inverter at ambient temperatures lower than -5℃.
•If a layer of ice has formed on the seal of the cover in sub-zero
comditions,remove it prior to opening the inverter(e.g. by melting the
ice with warm air). Observe the applicable safety regulation.

5. The ambient temperature should be below 40°C to ensure optimal operation.
6. Recommend to mount the inverter under the shaded site of the building or
mount an awning above the inverter.
7. Avoid exposing the inverter to direct sunlight, rain and snow to ensure optimal
operation and extend service life.
8. The mounting method, location and surface must be suitable for the inverter's
weight and dimensions.
9. 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.
10. Do not put any objects on the inverter.
11. Do not cover the inverter.

Installation and Operating Instructions V03 15
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.

16 Installation and Operating Instructions V03
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 required using a drill with 10 mm bit. 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 two screw anchors into the holes, then attach
the wall mounting bracket to the wall using the self-tapping screws and washers
delivered with the inverter.
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 the holes.
Risk of injury due to the heavy weight of the inverter
•When mounting, take into account that the inverter weighs approx. 7.5kg.

Installation and Operating Instructions V03 17
3.Holding the inverter and attach it tilted slightly downwards to the wall bracket.
4. Check both sides of the heatsink to ensure that it is securely in place.
5.Push the inverter as far as possible and attach it to both sides of the wall bracket
using the M5 screws.
If a second protective conductor is required in installation site, ground the inverter
and secure it so that it cannot be lifted off the wall bracket (see section 5.4.3
‛Second protective grounding connection“).
Dismante the inverter in reverse order.

18 Installation and Operating Instructions V03
5 Electrical Connection
5.1 Safety
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.
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").

Installation and Operating Instructions V03 19
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:
Damage to the inverter due to electrostatic discharge
• Touching electronic components can cause damage to or destroy the
inverter through electrostatic discharge.
• Ground yourself before touching any component.
