SLC X-PERT UPS auxiliary terminals.
5.2.3.1. External manual bypass.
The auxiliary contacts are located in terminals X10-1/2. A
normally open contact is required; when it is closed, the
microprocessor will obtain the status of the contact and turn
off the inverter.
5.2.3.2. Normal/Bypass selector.
The auxiliary contacts of this selector are located in terminals
X10-3/4. When the contact is closed, the UPS will transfer the
load from the inverter to the bypass.
5.2.3.3. External output switch.
The auxiliary contacts are located in terminals X10-5/6. This
contact is necessary to indicate the position of the disconnector.
If the external switch has not been provided, short-circuit
terminals 5 and 6.
5.2.3.4. Remote emergency power off button.
The auxiliary contacts are located in terminals X10-7/8. The
supply of voltage to the loads can be interrupted from a remote
location by using this contact. A normally closed contact is
required; when it is open, the static inverter and bypass switches
will open and the output power supply will be interrupted.
If the external EPO switch has not been provided, short-circuit
terminals 7 and 8.
5.2.3.5. Auxiliary batteries contact.
The auxiliary contacts are located in terminals X10-9/10. This
contact is necessary to indicate the position of the disconnector
(open-closed).
5.2.3.6. Auxiliary diesel generator contact.
The auxiliary contacts are located in terminals X10-11/12. A
normally open contact must be used; the contact must be closed
when the diesel generator is operating. The microprocessor
will acquire the state of the contact, and when the rectifier
is started, it will enable operation in ‘Diesel Mode,’ in which
operation is with DC voltage reduced to decrease the power
extracted from the AC line.
5.2.4. Serial interface.
The UPS is equipped with serial interfaces and external
connection ports for communication of operating status and
parameters.
