Title
1.1 Field of Applications
This installation manual is intended for Eaton certified installers. It describes how to securely install and
commission the following Eaton xStorage Home three phase (3P) hybrid inverters (Table 1):
Table 1. xStorage Home 3P system overview
1.2 Symbols used in this manual
1.2.1 Safety related icons
1.2.2 Hazard icons
Imminent dangers causing serious injuries.
Danger of death.
An electric shock can be fatal.
Avoid touching internal or external normally live parts whilst the system is powered on.
Surfaces can be hot.
The equipment contains capacitors that store static electricity, which could produce dangerous
electric discharges. Make sure that the devices have discharged their energy before carrying
out any work on the equipment.
Electromagnetic fields may have harmful effects (unknown to date) on the health of people who
are subjected to long exposure. Avoid standing for long periods of time at less than 20 cm from
the inverter.
The Guards or covers can be removed only 10 minutes after disconnecting the
inverter from the power supply to allow its components to cool down and any static
electricity storage devices to discharge.
Hazardous behaviors that could cause serious injuries.
Hazardous behaviors that could cause death.
Behaviors that could cause minor injuries to people or
minor damages to things.

1.2.3 Mandatory action symbols
1.2.4 Other symbols
Read the instructions. These instructions are intended for Eaton certified installers.
The notes preceded by this symbol relate to technical issues and ease of operations.
IP21 Protection class rating.
A threaded plug fuse cannot be used as a load circuit breaker.
Do not use measuring instruments with a maximum input voltage lower than 1000 V.
During the installation, make sure that the inverter is powered off.
The EU Directive on Waste Electrical and Electronic Equipment (WEEE).
Should the noise level exceed legal limits, the working area must be circumscribed and all the
people who have access to the area must wear ear defenders or ear plugs. The noise level
produced by the inverter in normal working conditions is: < 50 db.
A first aid kit must be provided. Do not underestimate burns or wounds.
The instructions provided in this manual do not replace the safety regulations and the installation
and operational technical data printed on the products, nor do they replace the current safety
standards enforced in the country where the equipment is installed, and the rules dictated by
common sense.
The Eaton certified installer must be an expert in the field and must therefore be responsible
for commissioning the system according to the manufacturer’s instructions and local legislation.
Any repair or replacement of parts of the system must be performed exclusively by Eaton
certified installers.
The ropes and vehicles used for lifting must be suitable for withstanding the weight of
the equipment.
