1. Connect the 5-pin DC power connector of the DC power cable (refer to Fig.5-26) to the appropriate DC power
connector (refer to #12, Fig.5-15) of the Operator Interface Computer 10"/15"/17” NEMA4 system, IP10IA99 /
IP15IA99 / IP17IA99. The DC power connector of the system is on the rear bottom side and is labeled “12V/24V
(+/-20%) DC”. Make sure the connector is locked tightly in place.
2. Ensure that the DC power source is switched off via an isolating switch, in order to ensure that no power is flowing
from the external power source during the connection procedure.
3. Connect the other end of the DC power cable (wires with lug terminals) (refer to Fig.5-26) to the terminals of the
24V DC power source. The wires of the DC power cable are labeled (+) and (-) to indicate their polarity. Ensure that
the power connections maintain the proper polarity.
4. Switch on the isolating switch in order to apply voltage to the terminals of the power source (cable wires).
5. Turn on the system via the power button (refer to “Power Button and Power LED”).
Hints for DC power connection: The DC power source should be able to be switched off and on via an
isolating switch. The unit is only completely disconnected from the DC main power source, when the DC
power cord is disconnected either from the power source or the unit. Therefore, the DC power cord and its
connectors must always remain easily accessible.
