4.5.4 Remote emergency power off (EPO)
Auxiliary EPO contact on terminals X10-7/8.
The voltage supply to the loads can be interrupted from a remote location by using this contact (i.e.
for safety requirements). A normally closed contact is required; when this contact is open the static
inverter and by-pass switches are opened so that the output supply is interrupted.
In case the external EPO command is not provided short-circuit the terminals 7-8.
4.5.5 Battery auxiliary contact
Battery auxiliary contact on terminals X10-9/10.
This auxiliary contact is necessary to indicate the position of the isolator (open-closed).
4.5.6 Diesel Generator auxiliary contact
Auxiliary contact from the Diesel Generator on terminals X10-11/12.
A normally open contact must be used; the contact must close when the diesel generator is
operating.
The microprocessor will acquire the status of the contact and, upon the rectifier start-up, it will
enable the "Diesel Mode" operation, that is the operation at reduced DC voltage in order to reduce
the power drawn from the AC line.
4.6 PROVISION FOR COLD START FUNCTION
At the terminal board a specific connector is avaialble, that is used to connect the pre-charge circuit
which is necessary for implementing the "Cold Start" function.
