installation, etc.
5.5.2 Grid connection
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. · The PE wire should longer 2 mm than L,N during strip the outer sheath of AC cable.
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 cover 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. Procedure: 1. Switch off the miniature circuit-breaker and secure it against being inadvertently switched back on. 2. Shorten L and N by 2 mm each, so that the grounding conductor is 3 mm longer. This ensures that the grounding conductor is the last to be pulled from the screw terminal in the event of tensile strain. 3. Insert the conductor into a suitable ferrule acc. to DIN 46228-4 and crimp the contact.

4. Insert the PE, N and L conductor through the AC connector housing and terminate them into the corresponding terminals of the AC connector terminal and make sure insert them

5.5.3 Residual current protection The inverter is equipped with an all-pole sensitive residual current monitoring unit (RCMU) with an integrated differential current sensor which fulfills the requirements of DIN VDE 0100-712 (IEC60364-7-712:2002). Therefore an external residual current device (RCD) is not required. If an external RCD needs to be installed because of local regulations, a RCD type A or type B can be installed as an additional safety measure. The all-pole sensitive residual current monitoring unit (RCMU) detects alternating and direct differential currents. The integrated differential current sensor detects the current difference between the neutral conductor and the line conductor. If the current difference increases suddenly, the inverter disconnects from the grid. The function of the all-pole sensitive residual current monitoring unit (RCMU) has been tested in accordance with IEC 62109-2.
Rating of the external residual current device · If an external residual current device (RCD) is required in a TT or TN-S system, install
a residual current device which trips at a residual current of 100 mA or higher. · For each connected inverter, a RCD with 100mA rated residual current has to be
provided. The rated residual current of the RCD must be equal to at least the sum of the rated residual currents of the connected inverters. That means that, if, for example, two transformerless inverters are connected, the rated residual current of the RCD must be at least 200 mA.
5.5.4 Overvoltage category The inverter can be deployed in grids of installation category III or lower, as defined under 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 overvoltage-reducing measures must be taken so that the overvoltage category is reduced from IV to III.

22

UM0023_ASW3000-6000-S-G2_EN_V02_0124

5.5.5 Grounding conductor monitoring The inverter is equipped with a grounding conductor monitoring device. This grounding conductor monitoring device detects when there is no grounding conductor connected and disconnects the inverter from the utility grid if this is the case. Depending on the installation site and grid configuration, it may be advisable to deactivate the grounding conductor monitoring. This is necessary, for example, in an IT system if there is no neutral conductor present and you intend to install the inverter between two line conductors. If you are uncertain about this, contact your grid operator or AISWEI-TECH.
5.5.6 Rating of miniature circuit-breaker
Danger to life due to fire · You must protect each inverter with an individual miniature circuit- breaker in order
that the inverter can be disconnected safely.
No load should be applied between the circuit-breaker and the inverter. Use dedicated circuitbreakers with load switch functionality for load switching. The selection of the 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 circuit breaker rating may be necessary due to self-heating or if exposed to heat. The maximum output overcurrent protection of the inverters can be found in section 10.2.
5.6 DC Connection

Danger to life due to high voltages in the inverter · Before connecting the PV array, ensure that the DC switch is switched off and that it
cannot be reactivated. · Do not disconnect the DC connectors under load.

7 Commissioning

Risk of injury due to incorrect installation · We strongly recommend carrying out checks before commissioning to avoid possible
damage to the device caused by faulty installation.
7.1 Electrical checks Carry out the main electrical tests as follows: 1. Check the PE connection with a multimeter: make sure that the inverter’s exposed metal
surface has a ground connection.

Danger to life due to the presence of DC voltage · Do not touch parts of the sub-structure and frame of PV array. · Wear personal protective equipment such as insulating gloves.
2. Check the DC voltage values: check that the DC voltage of the strings does not exceed the permitted limits. Refer to the Section 2.1 “Intended use” about designing the PV system for the maximum allowed DC voltage.
3. Check the polarity of the DC voltage: make sure the DC voltage has the correct polarity. 4. Check the PV array’s insulation to ground with a multimeter: make sure that the insulation
resistance to ground is greater than 1 MOhm.

Danger to life due to the presence of AC voltage · Only touch the insulation of the AC cables. · Wear personal protective equipment such as insulating gloves.
5. Check the grid voltage: check that the grid voltage at the point of connection of the inverter complies with the permitted value.

36

UM0023_ASW3000-6000-S-G2_EN_V02_0124

7.2 Mechanical checks
Carry out the main mechanical checks to ensure the inverter is waterproof: Make sure the inverter has been correctly mounted with wall bracket. Make sure the cover has been correctly mounted. Make sure the communication cable and AC connector have been correctly wired and
tightened.
7.3 Start-Up
After finishing the electrical and mechanical checks, switch on the miniature circuit-breaker and DC-switch in turn. Once the DC input voltage is sufficiently high and the grid-connection conditions are met, the inverter will start operation automatically. Usually, there are three states during operation: Waiting: When the initial voltage of the strings is greater than the minimum DC input voltage but lower than the start-up DC input voltage, the inverter is waiting for sufficient DC input voltage and cannot feed power into the grid. Checking: When the initial voltage of the strings exceeds the start- up DC input voltage, the inverter will check feeding conditions at once. If there is anything wrong during checking, the inverter will switch to the “Fault” mode. Normal: After checking, the inverter will switch to “Normal” state and feed power into the grid. During periods of low radiation, the inverter may continuously start up and shut down. This is due to insufficient power generated by the PV array. If this fault occurs often, please call service.
Quick Troubleshooting If the inverter is in “Fault” mode, refer to Section 11 “Troubleshooting”.
