4.2.2.3. Internal SNMP Communication
Internal SNMP can be installed into SNMP slot placed at the front rear of UPS. As soon as SNMP
installed, RS232 port would be disabled.
Internal SNMP has the same logic with External SNMP so please read
Section 4.2.2.1 for more
information.
4.2.2.4. SNMP Switch
If internal SNMP would be used, SNMP switch should be switched to SNMP side as indicated by the
arrows. If RS232 Serial Communication would be used, switch should be switched to RS232 side as
indicated by the arrows.
4.2.2.5. Emergency Power Off and Generator Connections
Upon request, UPS can be remote shut down and can make softstart to prevent the generator loaded
instantly when it is ON. For this purpose, there are two terminals on the Interface card which operate
with digital input.
Digital Inputs should be connected like dry contacts. Do not apply any voltage.
Input Function
UPS OFF (EPO)
If the UPS OFF Input is activated then UPS stops supplying the load.
When the energy is removed, UPS returns back to NORMAL operation
mode.
GEN ON
If GEN ON input is activated, then UPS reduces the absorbed current
from Generator during the transfer from Battery Mode to Normal Mode.
In case of internal SNMP use with UPS, serial communiation port (RS232) is disabled.
In order to activate the RS232 serial port, Internal SNMP should be removed.
If the switch is switched to SNMP side, RS232 Serial Communiation is disabled.
