5.1 Safety precautions
5.2 Preparing cables
Ÿ You are recommended to prepare firefighting equipment on
site, such as fire sand and fire extinguishers.
Ÿ Wear insulated gloves and use insulated tools to prevent
electric shock injuries.
Ÿ When exposed to light, the PV modules generate high DC
voltage which is present in the DC cables. Ensure that the DC
SWITCH on the inverter is set to OFF before connecting cables.
Ÿ Follow the wiring instructions specified in the user manual.
otherwise, any device damage caused by improper wiring will
not be covered under any warranty.
Ÿ Do not use single-strand wire as the output wire for the inverter.
Ÿ Do not use aluminum wire as the output cable.
Ÿ Wear insulated gloves to prevent static electricity from
damaging the components of the inverter.
Ÿ Unqualified persons shall not perform any electrical
connections.
Ÿ Avoid overstress on the cable, which could lead to poor contact.
Ÿ Damage caused by dust or moisture penetration due to
improper installation of waterproof connectors is beyond the
scope of warranty.
Ÿ When assembling cables, please keep a distance from the
inverter to prevent cable debris from falling into the inverter,
which might cause short circuits.

5.3 Preparing the AC breaker
Ÿ An external AC circuit breaker should be installed on the AC side of the inverter to
ensure a safe disconnection between the inverter and the grid.
Ÿ The AC breaker is not required to offer residual current protection as the inverter is
equipped with a sensitive residual current detection device (RCD). If local
regulations require the use of an AC breaker that incorporates residual current
protection, it is advised to install a type A or a type B RCD between the inverter and
the grid. The rated residual current must be greater than or equal to 300 mA.
Ÿ If an AC breaker with a rating greater than the recommended
specification or the value outlined in local regulations is used,
the inverter might fail to disconnect from the grid when an
exception occurs, which might lead to severe damage. Growatt
shall not be liable for the consequences.
Ÿ Each inverter must be equipped with an AC output breaker, and
multiple inverters cannot share the same AC breaker.
Ÿ Users are responsible for preparing the terminals for
connecting the AC breaker.
