10. Extended Warranty
The Stack Switchgear tracks usage and operating conditions throughout its lifetime.
It has a concept of
remaining life
for several of its components (e.g. fuse, contactors, relays). The
health of these components decreases with time and/or with events.
The
fuse
and
pre-charge resistor
's remaining lives are calculated by taking a baseline number
(TBD) and continuously substracting an amount dependent on current through them. The life of these
components decreases more rapidly at higher currents.
The
contactor
's remaining life is calculated by taking a baseline number (TBD) and substracting the
an amount (dependent on switching voltage and current) at every switching event. The impact of
switching under load is significantly higher than at no load.
The
safety relay
,
fan relay
, and
service disconnect switch
's remaining lives are calculated by
taking a baseline number (TBD) and substracting the an amount at every switching event.
In the event of a warranty claim, the remaining life of each component is queried. If the damage is
found to be related to a component that has been put under excessive stress (for example, a
contactor that’s been repeatedly switched under load), the warranty may be voided.
The Stack Switchgear is not designed to be opened and serviced in the field. Opening
the Stack Switchgear voids its warranty.
