When installing RS485, the COM sealing plate needs to be
removed. All operation MUST NOT proceed until AC and DC
power is securely disconnected and discharged to prevent
electric shocks.
6.2 Output Power Control via Smart Meter
The inverter can control active power output via connecting smart meter,
following is the system connection mode.
Smart meter as above SDM630-Modbus connecting method and setting
baud rate method for Modbus please refer to its user manual.
6.3 Demand Responsive Modes(DRMs)
DRMs Application Description
Only applicable to AS/NZS4777.2:2015.
•
Only DRM0 is available.
•
Users can close the S9 on DREDBOX to activate DRED function and
Operate the Disconnection Device by close S0. Other function of DRED is
all disabled.
The inverter shall detect and initiate a response to all supported demand
response commands.
Moistures and dust will damage the inverter
• Secure and tighten the screws on COM sealing plate.
• Warranty will be void if the inverter is damaged due to moisture and
dust caused by poor installation of COM sealing plate.

7. START UP AND OPERATION
7.1 Safety Check Before Start Up
Please check before switching on any voltage resources connected to the
inverter and closing inverter's DC switch:
1. Grid Voltage: Check the grid voltage at point of connection at the
inverter complies with permitted range of the inverter.
2. Mounting Bracket: Check if the mounting bracket is properly and
securely installed.
3. Mounting of the inverter: Check if the inverter is properly mounted and
attached to the mounting bracket.
4. DC Connectors: Check if the DC connectors are installed correctly on
terminals.
5. AC Connectors and Wire Assembly: Check if wires are assembled
correctly on the AC side and if the AC connector is properly and securely
installed. Check if the AC connector is firmly plugged into AC terminal.
6. Cables: Check if all cables are reliably connected. Check if the
connections are effective, while the insulations are undamaged.
7. Groundings: Check all groundings using multimeter and if all exposed
metal parts of the inverter are properly grounded.
8. DC Voltage: Check if the largest open-circuit voltage of PV arrays
complies with the permitted range.
9. DC Polarity: Check if the wires from DC voltage resource are connected
to terminals with correct polarity.
10. Grounding Resistance: Check if the grounding resistance of PV strings
>1MOhm using a multimeter.
After all installation and checks, close the AC circuit-breaker, then the
DC switch. The inverter will start to operate when DC input voltage and
grid conditions meet the requirements of inverter startup.
