Safety Instruction

1. The contents of this document will be updated irregularly for product version up- grade or other reasons. Unless otherwise specified,this document only works as guide. All statements, information and suggestions in this document do not constitute any guarantee.
2. This product can only be installed, commissioned, operated and maintained by technicians who have carefully read and fully understood the user manual.
3. This product must only be connected with PV modules of protection class II( in  accordance with IEC 61730, application class A).PV modules with a high capacitance to ground must only be used if their capacity does not exceed 1 F.Do not connect any sources of energyother than PV modules to the product.
4. When exposed to sunlight, the PV modules generate dangerous high DC voltage which is present in the DC cable conductors and live components. Touching live DC cable conductors and live components can result in lethal injuries due to electric shock.
5. Allcomponents must remain within their permitted operating ranges at all times.
6. Theproduct complies with Electromagnetic compatibility 2014/30/EU, Low Voltage Directive 2014/35/EU and Radio Equipment Directive 2014/53/EU.

Mounting Environment

1. Ensure that the inverter is installed out of the reach of children.
   
2. To ensure best operating status and prolonged service life, the mounting ambient temperature of the inverter shoul dbe ≤40°C.
   
3. To avoid direct sunlight, rain, snow, pounding on the inverter, it is suggested to mount the inverter in places with a top protective  roof. Do not completely cover the top of the inverter.
   
4. Themounting condition must be suitable for the weight and size of the inverter. The inverter is suitable to be mounted on solid wall that is vertical or tilted backwards
   (Max. 15°). It is not recommended to install the inverter on wall made of plaster-
   boards or similar materials. The inverter may make noise when working.
   
5. To ensure adequate heat dissipation, the clearances between the inverter and other objects are recommended as follows:

Inverter’smounting

Use a Φ10mm bit to drill 3 holes at a depth  of about 70mm according to the location of the wall mounting bracket.

Insert wall plugs into the wall and fix the wall mounting bracket to the wall by screwing three self-tappingscrews(SW10).

Hang the inverter to the wall mounting bracket.

Secure the inverter to the wall mounting bracket using M4 screw.

V.ACconnection

All electrical installations must be done in accordance with all local and national rules.

• Make sure that all DC switches and AC circuit breakers have been discon-
  nected before establishing electrical connection. Otherwise, the high
  voltage within the inverter may lead to electrical shock.
• In accordance with safety regulations, the inverter need be grounded firmly. When poor groundconnection(PE) occurs, the inverter will report PE
  grounding error. Please check and ensure that the inverter is grounded firmly or contact AISWEI service.

1. AC cable requirements are as follows. Insert the conductor into a suitable ferrule acc. to DIN 46228-4 and  crimp the contact .
   

   Object	Description	Value
   A	External diameter	9-14mm
   B	Copper conductor cross-section	2.5-6mm 2
   C	Stripping length of the insulated conductors	13mm
   D	Stripping length of the cable outer sheath	53mm
   The PE conductor must be 2 mm longer than the Land N conductors.

   

2. Loosen the swivel nut of AC connector. Insert the crimped conductors into correspondingterminalsandtighten screws  with the accompanied Allen key. Torque: 2.0Nm
   
3. Insert the adapter to the socket element,  stuff the seal ring into the adapter and  tighten the swivel nut.
   
4. Plug the AC connector into the socket for the AC connection.
   
5. If required, you can connect a second protective conductor as potentiality bonding.

VI.DC connection

• Make sure PV modules have good insulation against ground.
• On the coldest day based on statistical records, the Max. open-circuit volt- age of  the PV modules must not exceed the  Max. input voltage of the inverter.
• Check the polarit of DC cables.
• Ensure that DC switch has been disconnected.
• Do not disconnect  DC connectors under load.

1. Please refer to “DC Connector Installation Guide”.
2. Before DC connection, insert the DC plug connectors with sealing plugs into DC input connectors of the inverter toensureprotectiondegree.

VII.Communication setup

• Separate communication cables from power cables and serious interference sources.
• The communication cables must be CAT-5E or higher-level shield cables. Pin
  assignment complies with EIA/TIA 568B standard. For outdoor use, the communication cables must be UV-resistant. The total length of communication
  cable cannot exceed 1000m.
• If only one communication cable is connected, insert a sealing plug into the
  unused hole of sealingringofthecablegland.
• Beforeconnecting communication cables, ensure the protective film or  communication plate attached to the communication opening on the inverter is sealed tightly.

1. COM1: RS485(optional)
   RS485 cable pin assignment as below.
   

Pin 1=TX_RS485A
Pin 2=TX_RS485B
Pin 3=NC
Pin 4=GND
Pin 5=GND
Pin 6=NC
Pin 7=+7V
Pin 8=+7V

2.Loosen the swivel nut of the cable gland
on the communication cover, remove
sealing plugs and lead the cable through
the swivel nut, sealing ring, communicationcover and magnetic ring.

3.Insert the cable into the socket, attach the communication cover to inverter with M4 screws and tighten the swivel nut. Screwdriver type: PH2, torque: 1.6Nm.

COM2:GPRS/WiFi

Smart meter

1. Remove the communication plate from the inverter.
   
2. Loosen the swivel nut of the cable  gland on     thecommunication plate, remove the sealing plug and lead  the strippedcable through the cable gland and communication plate, press the latch of the smart meter terminaland insert thestripped cable accordingly. Make sure the cableis connected firmly.
   
3. Insert the smart meter terminal to the socket, attach communication plate tithe inverter with M4 screws, and tighten the swivelnut.Screwdrivertype: PH2, torque: 1.6Nm
4. If communication cover used, remove only one sealing plug of the cable gland to thread the cable.Detailed installation process follows above steps.

VIII.Commissioning

• Check that the inverter is grounded reliably.
• Check that the ventilationcondition surrounding the inverter is good.
• Check that the grid voltage at the point of connection of the inverter is within
  thepermittedrange.
• Check that the sealing plugs in DC connectors and the communication cable glandare sealed tightly.
• Check that grid connection regulations and other parameter settings meet
  safety requirements.

1. Switch on AC circuit breaker between the inverter and the grid.
2. Switch on DC switch.
3. When there is sufficient DC power applied and the grid conditions are met, the inverter will start to operate automatically.
