Clothing and PPE Worn by Staff
Installers are recommended to wear clothing and PPE provided by their employer. Staff must not wear
clothes or accessories that could start res or produce static electricity or, generally speaking, any item of
clothing that could affect personal safety. When carrying out any operation on the equipment, clothes and
instruments must be suitably insulated.
Ex: class 0, category RC insulated gloves
Maintenance operations must be strictly carried out with the equipment disconnected from the mains, from
the PV generator and from the batteries.
Staff must NOT access the equipment with bare feet or wet hands.
The maintenance engineer must always ensure that nobody else is able to reset or operate the equipment
during the maintenance stages and must report any fault or deterioration caused by wear or by aging, in
order to restore the correct safety conditions.
The installer or maintenance engineer must always pay attention to the working environment, to ensure it
is well lit and has a suitable escape route.
A rst aid kits must be provided.
Do not underestimate burns or wounds.
2.4 Protection from Electric Shock
An electric shock can be fatal.
Avoid touching internal or external normally live parts whilst the system is powered on.
Cables and connections must always be secured, in good conditions, insulated and suitably sized.
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.
2.5 Electromagnetic Fields and Interferences
Electromagnetic elds 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 20cm from the inverter.
The installer must be an expert in the eld and must therefore be responsible for commissioning the system
according to the manufacturer's instructions and local legislation. Should electromagnetic interferences be
detected, the installer must solve the problem by contacting the manufacturer's technical support service.
In any case, electromagnetic interferences must be reduced so that they no longer cause disruptions.
Connect to ground the DLS external frame or other conductive parts to ensure best protection to the system
and best safe to the operators.
National standards related to grounding must be complied with.
