2. Safety
DT series inverter of Jiangsu GoodWe Power Supply Technology
Co.,Ltd. ( hereinafter referred to as GoodWe ) strictly conforms to
related safety rules in design and test. As electric and electronic
equipment, Safety Regulation shall be followed during installation
and maintenance. Improper operation may bring severe damage to
the operator, the third party and other properties.
The installation and maintenance of the inverters must be performed
by qualified personnel only in compliance with national and local
standards and regulations.
Before installation and maintenance, DC input and AC output of the
inverter should be cut off beforehand and the inverter cannot be
touched within 10 minutes after power cut-off in case of electric
shock.

3/ 56
Partial temperature of the inverter may exceed 60 ℃during
operation, please do not touch in case of scalding.
All electric installation should conform to local electric standard and
permission has to be obtained from local power supply department
before synchronization by qualified personnel.
Children must be kept away from inverters.
Please do not open the front cover of inverter. Apart from wiring
terminal, touching or changing components without authorization
may cause damage to people and inverters. GoodWe may deny the
obligation of warranty service accordingly.
Static electricity may damage electronic components and proper
measures shall be adopted to avoid static electricity.
The output voltage of proposed PV array should be lower than the
inverter maximum rated input voltage; otherwise, GoodWe will not
undertake any obligations and warranty services.
Please switch off the breaker between PV-Inverter and Grid (utility)
firstly before any service. Or else electric hazards will be caused.

3.3. Equipment Installation
3.3.1 Selecting the installation position
Installation position should be selected based on the following
aspects:
The installation method and mounting location must be suitable for
the inverter's weight and dimensions.
Mount on a solid surface.
Select a well ventilated place sheltered from direct sun radiation.
Install vertically or tilted backward by max 15°. The device cannot
be installed with a sideways tilt. The connection area must point
downwards.

3.4 Electrical Connection
You must comply with the connection requirement of local regulations.
The inverter is integrate with an RCMU according to VDE0126-1-1/A1.
It monitors residual current from the solar module to grid side of
inverter. The inverter can automatically differentiate between fault
current and normal capacitive leakage currents.
3.4.1 Connection to Grid (AC Side Connection)
ACheck the grid (utility) voltage and frequency at the connection
point of the inverter. It should be phase to phase 400VAC, 50Hz and
three phases.
BCheck the rating of branch circuit breaker. For installing one unit of
6K, 10K or 12K inverter, the recommended breaker rating is
400V/25A. For installing one unit of 15K or 17K inverter, the
Padlock hole ¢5.0

13 / 56
recommended breaker rating is 400V/32A.
CDisconnect the breaker or fuse between PV-Inverter and utility.
D Connect the inverter to the grid as follows:
Switch off the AC Breaker.
Disassemble female connector of the AC wire connector and connect
AC wires to connection socket as indicated.
Figure 3.4.1-1
Insert AC wire to AC socket according to below table and figure.
Caution!
