Installazione e avviamento INGENIO PLUS UPS 30÷40 kVA
38 OMS02082 REV. D
4.5 CONNECTION OF THE AUXILIARY CABLES
The UPS systems of the INGENIO PLUS 30÷40 kVA line can be connected to external
controls/components specifically designed to improve the safety and reliability of the device.
External manual bypass (MBCB);OPTIONAL
External Normal/Bypass selector switch; OPTIONAL
External output switch (OCB); OPTIONAL
Remote emergency power off button (EPO); OPTIONAL
Auxiliary battery contact (BCB).
Diesel generator; OPTIONAL
The auxiliary cables are connected to a dedicated terminal board. Wires up to 4 mm
2
can be
connected to the terminals.
Auxiliary contacts of OCB - MBCB - BCB
The auxiliary contacts of the external switches MBCB, BCB and OCB (if provided)
must be mandatorily connected to the UPS.
4.5.1 External manual bypass OPTIONAL
Auxiliary contact of the external Manual Bypass Switch (if provided) on terminals
OF PCB EXT-INP 1/2.
A normally open contact is required; when the contact is closed (see Manual Bypass
procedure), the microprocessor will acquire the status of the contact and shut down the inverter.
4.5.2 NORMAL/BYPASS selector OPTIONAL
Auxiliary contact of the external NORMAL/BYPASS selector on terminals OF PCB EXT-INP 3/4.
When the contact is closed the UPS will UPS will transfer the load from inverter to bypass.
4.5.3 UPS output switch OPTIONAL
Auxiliary contact of the external UPS output switch (if provided) on terminals
OF PCB EXT-INP 5/6.This auxiliary contact is necessary to indicate the position of the isolator
(open-closed)..
In case the external switch is not provided short-circuit the terminals 5-6.
4.5.4 Remote emergency power off (EPO) OPTIONAL
Auxiliary EPO contact on terminals OF PCB EXT-INP 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 X10-1/2.
This auxiliary contact is necessary to indicate the position of the isolator (open-closed).
