· M6x60 expansion bolts are delivered with the solar inverter. If the length and number of the bolts do not meet installation requirements, prepare M6 stainless steel expansion bolts by yourself.
· The expansion bolts delivered with the solar inverter are mainly used for solid concrete walls. For other types of walls, prepare bolts by yourself and ensure that the wall meets the load bearing requirements of the solar inverter.
· In residential areas, do not install the solar inverter on drywalls or walls made of similar materials which have a weak sound insulation performance because the noise generated by the solar inverter is noticeable.
· Loosen the nut, flat washer, and spring washer of the expansion bolt at the bottom. Level
2. (Optional) Install the screw for locking the DC switch.
3. Install the solar inverter onto the mounting bracket. 4. (Optional) Install an anti-theft lock.

3 Connecting Cables
3.1 Preparing Cables

· Connect cables in accordance with the local installation laws and regulations. · Before connecting cables, ensure that the DC switch of the solar inverter and all the switches
connected to it are set to OFF. Otherwise, the high voltage produced by the solar inverter may cause electric shocks.
Prepare cables based on site requirements.

is reserved.

3.3 Installing a WLAN Antenna

Antenna port (ANT)

Ensure that the WLAN antenna is installed securely.
3.4 Installing the AC Output Power Cable
Ensure that the protective layer of the AC output power cable is inside the connector, that the core wires are totally inserted into the cable hole, and that the cable is connected securely. Failing to do so may cause device malfunction or damage. 1. Connect the AC output power cable to the AC connector.

3.5 Installing DC Input Power Cables

1. Ensure that the PV module output is well insulated to ground. 2. Use the Staubli MC4 positive and negative metal terminals and DC connectors supplied with
the solar inverter. Using incompatible positive and negative metal terminals and DC connectors may result in serious consequences. The caused device damage is not covered under warranty. 3. The DC input voltage of the solar inverter must not exceed maximum input voltage. 4. Before installing DC input power cables, label the cable polarities to ensure correct cable connections. 5. If DC input power cables are reversely connected, do not operate the DC switch as well as positive and negative connectors immediately. Failing to do so may cause device damage, which is not covered under warranty. Wait until the solar irradiance declines at night and the PV string current reduces to below 0.5 A, and then turn off the DC switch and remove the positive and negative connectors. Correct the string polarity before reconnecting the PV string to the solar inverter.

Y-branch connectors can be used to connect multiple PV modules to a SUN2000. However, it is recommended that the same number of PV modules be connected to each Y-branch connector. Use the Staubli Y-branch connectors, MC4 positive and negative metal terminals, and DC connectors. Those of other brands may be incompatible and cause damages, which will not be covered under warranty.
3.6 Installing Signal Cables
· When laying out a signal cable, separate it from power cables to avoid strong signal interference.
· Ensure that the protective layer of the cable is inside the connector, that excess core wires are cut off from the protection layer, that the exposed core wire is totally inserted into the cable hole, and that the cable is connected securely.
· Block the unused cable hole using a cap and tighten the cable gland. · If more than one signal cables are required, ensure that they have the same outer diameter.

3.7.2 Connecting the AC Input Power Cable

Connect AC input power cables of the SmartACBox to input circuit breakers QF01 to QF05 and QF07 to QF11. It is recommended that AC input power cables be routed to input circuit breakers QF01 to QF05 through AC input cable hole 1 and be routed to QF07 to QF11 through AC input cable hole 2.
1. Remove an appropriate length of the jacket and insulation layer from each AC input power cable using a wire stripper.

· The lengths of the jackets and insulation layers that need to be removed from the AC input power cables to input circuit breakers QF01 to QF05 are different. When connecting a stripped cable, ensure that the exposed insulation layer is in the enclosure, and the jacket is outside the enclosure.
· For the lengths of the jackets and insulation layers that need to be removed from the AC input power cables to input circuit breakers QF07 to QF11, refer to the AC input power cables to input circuit breakers QF01 to QF05.
