1.6. Information about the presence of foreign materials in the vicinity of UPS
equipment installations
Warning
The purpose of this note is to provide information and warnings on a potential risk to the
operational integrity of an installed UPS system, as posed by the presence of foreign
material inside or in the vicinity of the UPS module and its 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 subsequent
degradation or loss of power to the connected critical site load.
Vertiv applies 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 during operation (built to IP20, with optional
filters available for special conditions).
However, it is not possible for Vertiv to ensure that foreign bodies will not be introduced
during on-site installation, or when the UPS doors & covers are "open" and the electrical
terminals are exposed to allow power line connections to be made by the electrical
contractor/installer.
It is also not uncommon to have other personnel working in the same (UPS equipment)
room during on-site installation. Such personnel sometimes work above the UPS
equipment and associated auxiliary equipment/components.
To prevent major disruption to site operations and risk to property and personnel,
including the possibility of a fatality, each site's facility manager or construction
manager must prevent foreign bodies from being introduced into the UPS module
and associated auxiliary equipment/components.
All UPS modules and associated auxiliary equipment/components are thoroughly
inspected by Vertiv engineers prior to placement into service and testing on-site. When
conductive foreign bodies are identified, our engineers are instructed to interrupt all work
until the equipment and the area have 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, are kept
clean and free from any possible conductive material such as metal foil, food wraps, cable
shields, washers and other hardware, scrap metal, scrap and dust.
If the UPS system is shut down after placement into service & testing are completed, the
UPS room must be kept clean to avoid the possibility (during restart) of the considerable
volume of air-flow produced by UPS operation to dislodge and/or drag any foreign bodies
into the equipment, which would result in system failure and possible supply interruption
to the critical site load, and several hours of downtime resulting from the damage typically
associated with such events.
