Connect To Power Supply - GE PACSystems RX3i CPE400 Quick Start Manual

Connect to Power Supply

The 24Vdc power input connector is located on
the underside of the CPE400, as shown in Figure 8.
The signal pinouts are also indicated.
The mating connector for the CPE400 24Vdc
power input is the 3-pin Phoenix 1827716 shown
in Figure 9. The power supply cable prepared by
the user must use the specified mating connector.
The positive "+" and negative "-" signals are
required. FGND is optional, but recommended.
For the mating connector, the compatible
conductor size is from 24AWG to 16AWG. Strip the
wires back 7mm before inserting into the
connector. Tightening torque for the three signal
screws is 2.2 in-Ibs (0.248Nm). Secure the mating
connector to the power input connector via the
two captive screws provided.
The user-supplied SELV
supply voltage in the range of 18Vdc to 30Vdc.
Once the power supply cable (or compatible
Energy Pack ACC403) has been attached to the
CPE400 and the power supply has been turned on,
the unit will start booting. There is no need to push
any button.
The unit is equipped with built-in reverse polarity
protection. If + and - are swapped the unit will not
power-up. If + is connected to FGND, this will
cause a short. The power supply needs to protect
itself against this condition.
Inrush Current
The CPE400 may experience an inrush current of up to 49A for 15µs.
