3.4 Electrical Installation for DC Wiring
DANGER : ELECTRICAL HAZARD!!
– PV arrays convert sunlight into electric power with high DC voltage and high DC current which can cause dangerous electrical shock! – Use opaque material to cover the PV arrays before wiring or cabling. – Ensure the correct polarities are connected when DC cabling is applied. – The amount of PV module of each string within one MPPT should be the same to avoid the circulating current between the strings.
WARNING !
– The inverter may overheat and catch fire under fault conditions. – Only PV modules that are listed with system voltage under 1100V are permitted
for use. – Make sure the DC switch is in the “OFF” position, and disconnect the PV array
before plug in/out the DC connectors. – Inverter warranty void if the DC input voltage exceeds 1100 Vdc.
ATTENTION
– The PV Array current carrying conductors (positive or negative) must not be referenced to ground.
– Before plug in the DC connectors, please notice the polar of connectors. Reverse positive and negative voltage will make damage.

– Do not remove the waterproof plug for unused DC strings.

ATTENTION
– According to different local regulations, if the external string fuse is required, please contact Delta dealers.

Please read the following instructions for connecting DC connector : · Ensure the DC conductors used are Cu and sized to the correct ampacity per
NEC or other local code · Strip off all wires for 6.5~7.5 mm. · The cross- sectional area for each DC conductor is 12~10 AWG (4~6 mm²). · Choose the DC string wire size based on NEC requirements or other local code.
M30A_230 uses H4 type connectors mounted on the bulkhead to connect the string to the inverter. Mating connectors (See Figure 3-13) are provided within the packing.

3.6.1 Accessing the Communication Module
The communication module consists of an assembly with a PCB and a plastic carrier. It is located in slot through the bottom of the chassis. It can be accessed from the chassis bottom outside. The carrier is fixed to the chassis by two self-retaining screws. See Figure 3-17. Loose the self-retaining screws from the chassis, and gently pull the carrier straight out of the chassis to withdrawthe communication module. After passing the required signal cable through the wiring gland provided or a connected conduit and making the electrical connections as shown in the following sections, the module can be reinstalled in the opposite direction described above.

ATTENTION
This inverter is compliant with the “Technical Specification for Security Inspection of Solar Inverter and Monitoring Units” required by BSMI. After completing the communication wiring, please apply a brand new one-time-use security seal (item 9, Table2-1) on the carrier. We will not be liable or responsible for any security incident caused by an improper application of the sticker.

Installation

3.6.2 RS-485 Connection
The pin definition for the RS-485 terminal block is shown in Table 3-2. – Pins 1 and 2 provide a 12VDC bus for use with accessories.
(If use of the 12VDC bus is necessary, please set switch 1 to the ON position.) – Pins 3 and 5 are both connected to the DATA+ input. – Pins 4 and 6 are both connected to the DATA – input. These connections allow easy daisy- chaining of multiple inverters. A 120ohm bus termination resistor and associated control switch are located on the communication board. The switch function is as shown in Table 3-3. Different RS-485 connection scenarios require different set up for the 120ohm bus termination resistor. · When multiple inverters are cascaded (i.e., “daisy-chained”), only the last inverter
in the chain must have its bus termination resistor switched ON.(Figure 3-18) · If the length of any RS-485 bus is greater than 610m, it is recommended to use
Belden 3105A cable (or equivalent cable) to ensure communication quality.
ATTENTION
– It is recommended to use twisted-pair as a communication cable for well transmission quality.

3.7 Wi-Fi
The communication module supports the inverter to communicate with devices (such as smartphones, tablets, etc.) via Wi-Fi (base WPA2-PSK). User can restart the function through the APP or DSS. There is an antenna for Wi-Fi in the package (item 8,Table 2-1), which must be mounted on the plastic carrier as the procedure below. 1. Remove the protective nut. 2. Tighten the antenna.
Figure 3-22: Installation of Wi-Fi antenna
ATTENTION
– Please properly install the antenna as shown below to keep communication quality and avoid equipment damage.
– More detail for Wi-Fi connection and APP : https://mydeltasolar.deltaww.com/index.php?p=manual
– To establish a successful communication between Inverter Wi-Fi to MyDeltaSolar Cloud, in the Wi-Fi connection setup page, the signal strength must be above -70dBm between each Wi-Fi device (Wi-Fi router, inverter, DC1…etc.). In case the signal strength is below -70dbm, it may cause certain communication errors which may prevent a successful Wi-Fi communication. To avoid such issues, please adjust the Wi-Fi device position to improve the signal strength/quality.

Maintenance

5cMaintenance
Regular maintenance can ensure that the inverter maintains great performance. DELTA recommends that the unit should be inspected at least every 6 months. The maintenance frequency should be adjustable, depending on the sit environment, different seasons and weather effects.
DANGER : ELECTRICAL HAZARD!!
– Make sure that both AC breaker and DC switch are turned off and the LED indicators are off to avoid the risk of electric shock!
5.1 Open and Close the Door
In order to ensure the normal long-term operation of the inverter, the M30A_230 door must be opened and closed according to the following step.
5.1.1 Open Door
WARNING ! – Do not attempt to open the door under raining condition. – Before opening the front door, please wipe the inverter case if it is wet to
avoid water seepage. 1. Loosen the screws on both latch covers with hexagon wrench attached on the
latch cover. (Figure 5-1) 2. Open the latch covers and release latches to open the door. (Figure 5-1) 3. Use the hexagon wrench to secure the door from closing. (Figure 5-2)

5.1.2 Close Door
ATTENTION
– Due to corrosion of live parts, excessive moisture or dust in the inverter may cause accidental damage. Ensuring that the inner of the inverter is clean free from unreasonable pollution is important for long service operating systems.
– After cabling or maintenance for the inverter, please lock both toggle latch to make sure the inverter will remain IP66 protection.

1. Ensure that the gasket in the mounting slot and mating surface on the enclosure are clean and in good condition.
2. Make sure all protective covers are properly installed. 3. Remove the hexagon wrench and close the door. 4. Buckle the latch and apply a one-time- use security seal (item 9, Table 2-1) on
the top toggle latch as the following attention. 5. Secure the latch cover with the hexagon wrench. 6. The hexagon wrench can be fixed on the latch cover.

ATTENTION
– This inverter is compliant with the “Technical Specification for Security Inspection of Solar Inverter and Monitoring Units” required by BSMI. After closing the door, please apply a security seal on the toggle latch. We will not be liable or responsible for any security incident caused by an improper application of the sticker.

Maintenance
5.5 De-Commissioning
If it is necessary to remove the inverter from active operation for maintenance or replacement, please follow the instructions below.
DANGER : ELECTRICAL HAZARD!!
To avoid serious injury, please follow the procedure below.
CAUTION : HOT SURFACES, DO NOT TOUCH !
– Please be careful of hot surfaces if the inverter is just shutting down. – Not to do any maintenance until inverter is sufficiently cooled down.
CAUTION : POSSIBILE INJURY !
The inverter weighs 42 kg (92 lb). When the inverter is improperly handled or dropped during transportation or removed from the rack, it may cause personal injury.
– Switch off external AC circuit breaker or switch to disconnect the electrical grid from the inverter chassis.
– Switch off the DC switch to cease inverter operation. – Use H4 wrench tool to disconnect each string from the chassis mounted H4terminals. – Remove Wi-Fi antenna from the bottom of the cassis.
RS-485 Communication module 1. Remove the communication module from inverter. 2. Remove all communication cables from the module terminals. 3. Reinstall the communication board assembly in inverter.
