3.4.4.1.
AC mode (X6 to X10)
The equipment has 3 output phases (U, V and W) which are referenced to the neutral point of
the system (N). Therefore, the EUT must be connected between one of the phases and the
neutral point (phase-N) or between two phases (phase-phase):
-
Output phase U (
X6
)
-
Output phase V (
X7
)
-
Output phase W (
X8
)
-
Neutral point N (
X9
)

Emergency Power Off terminals (X12)
CINERGIA units are equipped with a local Emergency Stop pushbutton at the front panel. When
this local pushbutton is pressed, the unit will be completely switched off by disconnecting the
main contactors at the input and at the output. For safety reasons, the operation is done by
hardware.
In addition, CINERGIA units also integrate two terminals dedicated to an external Emergency
Power Off (EPO). When these terminals are used, the unit will have two Emergency Pushbuttons
active: the local pushbutton and the external-remote pushbutton. This document describes the
connection of the external-remote pushbutton (hereafter EPO).
WARNING: the internal circuitry will be damaged if an external power supply is
connected to X12 (J15) EPO terminals. Do not connect an external power supply or
active signal. Only Normally Closed dry contact is allowed.
