Before connecting to the grid and the load, please install a separate AC breaker (250VAC/30A) between the inverter and
the grid. This will ensure the inverter can be securely disconnected during maintenance.
It's very important for system safety and efficient operation to use appropriate cable for the AC connection. To reduce risk
of injury, please use the suitable recommended cable size. Refer to Figure 4.1-1.
Please adhere to the following steps when making an AC connection:
(
1
)
Check the grid voltage and frequency at the connection point of the inverter. It should meet the Zeus Appollo Solar products'
specification.
(
2
)
Measure the impedance between neutral cable and earth cable, make sure it does not exceed 10 ohms.
(
3
)
Disconnect AC breaker between the inverter and the Grid.
(
4
)
Disconnect the screw cap from the insulator.
(
5
)
Disconnect waterproof ring from insulator.
(
6
)
Feed the cable through the components in this order: screw cap,waterproof ring, insulator, AC cover and AC terminal.
Refer to Figure 4.1-2.
(
7
)
Compress the terminal head using an appropriate tool and screw down the screw cap slightly. Refer to Figure 4.1-3, Figure 4.1-4.
(
8
)
Insert AC terminals into the corresponding holes and fasten them by a screwdriver
(
Suggestion: diameter
of
the cutter bar is
4mm,
torsion:8~12Kg-f.cm), then fasten the AC cover with pan head screws in the accessory bag. Refer to Figure 4.1-5, Figure 4.1-6,
Figure 4.1-7.
(
9
)
Screw down the screw cap again.

Remember that this inverter is heavy! Please be careful when removing from the packaging.
1. Use the wall-mounted bracket as a template and drill 6 holes on the wall, 10mm in diameter and 80mm deep.
Refer to Figure 3.4-1.
2. Fix the wall-mounted bracket on the wall with six expansion bolts in the accessory bag.
3. Carry the inverter by holding the heat-sink two sides. Refer to Figure 3.4-2.
4. Place the inverter on the wall-mounted bracket. Refer to Figure 3.4-3,
Figure 3.4-4.
