Information about the presence of foreign materials
in the vicinity of UPS equipment installations
The purpose of this note is to provide information and warning regarding a potential risk to the opera-
tional integrity of an installed UPS system, posed by the presence of foreign material inside or in the
vicinity of the UPS module and the associated auxiliary equipment/components.
This risk is especially high if conductive materials find their way inside the UPS module or the associated
auxiliary equipment/components.
The risk potentially involves damage to the installed UPS equipment, and subsequently degradation or
loss of power to the connected critical site-load.
Chloride SpA employs the highest safety standards in equipment design, to ensure that no live parts are
exposed to external contact, and also to ensure that the equipment is protected against the introduction
of foreign bodies when operational (built to IP20 with optional filters available for specific conditions).
However, it is not practically possible for Chloride SpA to ensure that foreign bodies will not be intro-
duced during the site installation works, when the UPS doors & covers are "open" and the electrical-ter-
minals are exposed for power-line connections to be made by the electrical contractor/installer.
It is also not uncommon to have other trades working in the same (UPS equipment) room during the site-
installation period, sometimes involving working above the UPS equipment and associated auxiliary
equipment/components.
To avoid the possibility of a major disruption to site operations, and risks to property and per-
sonnel, including the possibility of a fatality, it must be the responsibility of each site's facility
manager or construction manager, to ensure that the introduction of foreign bodies to the UPS
module and associated auxiliary equipment/components is prevented.
UPS modules and their associated auxiliary equipment/components are all thoroughly inspected by
Chloride SpA engineers prior to any commissioning and testing works being performed on site. Our en-
gineers are instructed to abort all live work upon identification of conductive foreign bodies until the
equipment and area has been thoroughly cleaned of any contaminants.
However, the person responsible for the site must ensure that the UPS module and associated auxiliary
equipment/components, and the immediate surroundings is kept clean and free of any possible conduc-
tive material such as metallic foil, food wraps, cable shields, washers and other hardware, scrap metal,
swarf and dust.
If the UPS system is shutdown after the commissioning & testing works are completed, the UPS room
must be kept clean to avoid the possibility (during restart) of the considerable volume of air-flow pro-
duced by UPS operation to dislodge &/or drag any foreign bodies into the equipment resulting in system
failure and possible supply interruption to the critical site-load, and several hours of downtime occa-
sioned by the damage typically associated with such events.
If the UPS is left running/operational at the completion of the commissioning and testing works, the room
similarly needs to be kept clean to avoid ingress of any foreign bodies into the UPS module via the UPS
forced air-flow.
Chloride SpA will not accept any liability or expenditure associated with incidents caused by the pres-
ence of introduced conductive foreign bodies in the UPS module or associated auxiliary equipment/com-
ponents originated during pre-commissioning or post-commissioning activities within the UPS
environment.
