ModularEasy
MX ModularEasy
enables parallel
operation when combining two
MX
UPSs.
Consequently you can enhance the
availbility level of your equipment (N+1
redundancy). You can also double your
secured power capacity according to your
needs (migration, network extension...).
In the unlikely event a major fault would
occur, the manual maintenance bypass of
MX ModularEasy
would allow the UPS
maintenance without interrupting your
connected equipment.
In single unit mode,
MX ModularEasy
combined with one
MX
UPS adds a
second level of availability to your
installation.
The manual bypass mode allows the
replacement of the UPS without any
interruption to the connected equipment
in case of a major fault that would not be
related to the most critical components of
the UPS (i-e front-accessible, hot-
swappable Battery and Power Sub-
Modules).
