NEUTRAL SYSTEM:
Keor T does not modify the neutral system: output neutral system is the same as
input neutral system. Do not connect the output neutral to the protective ground
or protective bounding (PE or PB).
Installation of an external isolation transformer is required when necessary to
modify the neutral system downstream Keor T.
To enable the short circuit protection feature of the UPS, each load should be
supplied through a separate circuit breaker chosen according to the load current.
This may provide quick disconnection of the short circuited load and maintain
operation continuity of the other loads.
Each load should be supplied through separate circuit breaker and the cable cross
section should be chosen according to the load current value.
Make sure that the UPS is not overloaded to provide a higher quality supply to the
loads.
