5.3.1 Power Connector
Fig.5-16: DC Power connector on the bottom (rear) side of the OIC Panel system
The DC Power connector (refer to Fig.5-15, #11 and Fig.5-16) provides the power connection of the Operator
Interface Computer 10"/15"/17” NEMA4 system, IP10IA99 / IP15IA99 / IP17IA99 to the main power source via the
DC power cable or the AC/DC adapter.
5-pin terminal block connector for power inlet from the adaptor to the unit. 3-pin is the power (V+ / NC / V-)
supplied from a wide input range DC +12V ~ +24V (± 20% tolerance); while the other 2-pin serves the UPS-like
purpose. If the AC power source is failed and no power inputs to the DC adaptor, the other 2-pin on the right side
of the connector can supply the power to the unit from the standby UPS.

5.3.1.1 Power Button and Power LED
The Operator Interface Computer 10"/15"/17” NEMA4 system, IP10IA99 / IP15IA99 / IP17IA99, provides a power
button (refer to #4, Fig.5-13) and a power LED (refer to #5, Fig.5-13) on the front panel.
The power button allows to Power ON/OFF Operator Interface Computer 10"/15"/17” NEMA4 system, IP10IA99 /
IP15IA99 / IP17IA99, depending on the settings for the power button in BIOS Setup (default setting is Power/After
Power Failure/ON).
The power LEDs show the ON/OFF state of the system. The OIC (Operator Interface Computer) 10"/15"/17”
NEMA4 system, IP10IA99 / IP15IA99 / IP17IA99 is equipped with a power LED on the front panel (refer to Fig.5-17).
An additional power LED (PWR) is available on bottom (rear) side of the system (refer Fig.5-18).
