There are “L1”, “L2”, “N” and “ ” symbols marked inside the connector ( see
Figure 4.11), the Line wire must be connected to
“
L1
”
and “L2” terminals; the
Neutral
wire must be connected to
“
N
”
terminal; the Earth of grid must be connected to
“
”
(see Figure 4.5).
WARNING:
Please refer figure 4.2 to connect the DC1 and DC2 in the DC terminal of inverter, then
connect the ground wire of two DC input. The DC wire connected to DC terminals (shown
in Fig. 4.5) is recommended AWG12-8, and the fuse is KLM-20 of Cooper Bussmann, only
professional can replace it.
The inverter is suitable for both 208V and 204V grid. Please connect the L1, L2 and N in
the AC terminal, and connect the ground on the ground terminal.The AC wire connected to
AC terminals (“L1”, “L2” shown in Figure 4.5) is recommended AWG 8, and the fuse is
KLM-30 of Cooper Bussmann, only professional can replace it.
Damage to the inverter through the use of fuses as disconnecting units in the
output circuit of the inverter
WARNING:
Damage to the DC Disconnect due to enlarged knockouts
Enlarged knockouts enable moisture to penetrate the DC Disconnect which
could damage electronic components in the DC Disconnect.
Note:
4.3.2 Connect grid side of inverter
Before electrical connection Please make sure below steps are strictly followed:
a. Switch the Solar Supply Main Switch (AC) OFF.
b. Switch the solar panel DC Isolator OFF.

Warning
Before connecting inverter, please make sure the PV array open circuit voltage
is within the limit of the inverter. Otherwise the inverter could be damaged.
Please don’t connect PV array positive or negative pole to the ground, it could
cause serious damages to the inverter
Please use qualified DC cable for PV system.
