9.1.5 EPO (Emergency Power Off)
Be aware:
The reliability of the system depends on this contact NC (Normally Closed)!
An external Emergency switch (Normally Closed voltage-
free contact) can be connected on terminals X2 / 1, 2 or
connector J2 / 12, 25 of the P4 - Interface Customer.
Remove the cable short-circuiting terminals X2 when using
this external switch.
When opened, this contact causes the immediate opening
of the Contactors K3, K4, K6, K7 and K8, as well as the
shutdown of Rectifier, Inverter and Static-Switch.

NOTE !
This procedure could imply a load shutdown.
NOTE !
To enable this function, remove jumper JP3 on the P4 - Customer Interface, when the
cables have already been connected on X2 or J2.
In case of parallel Customer Interface (up to 3) the EPO contact must be connected to
one Customer Interface only, but the bridge on X2 and jumper JP3 on the P4 –
Customer Interface must be removed on all other boards.
In a parallel system a separate NC (Normally Closed) contact must be connected
individually to each unit.
When the EPO has been activated, the system must be restored as follows:
• Press the push-button EPO (contact on X7 / 1, 2 is closed again).
• Press the key “O” (inverter off – see Section 6.2) on the control panel.
In case of a parallel system press the key “O” (inverter off) on the control panel of
each unit connected on the parallel bus and having its output switch Q1 closed.
