Make sure that all circuit breakers are at “OFF” position before starting with the
installation.
NEUTRAL SYSTEM :
KEOR T EVO 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.
Connect the phase cable to X2 OUTPUT: X2/L1 – X2/L2 – X2/L3 terminal and the neutral cable to X2
OUTPUT: X2/N terminal.
Cables must be protected by fuses or MCCB, refer to Section 5.4
