To Install The Ppda I/O Pack - GE Mark VIeS System Manual

10.2.4 Installation
Caution
➢ ➢ To install the PPDA I/O pack
1. Securely mount the desired terminal board.
2. Directly plug the PPDA I/O pack into the JA1 terminal board connectors. The PPDA I/O pack mounts on a JPDG or
JPDS 28 V dc control power distribution board. Refer to the section
3. Mechanically secure the I/O pack using the threaded studs adjacent to the Ethernet ports. The studs slide into a mounting
bracket specific to the terminal board type. The bracket location should be adjusted such that there is no right-angle force
applied to the DC-62 pin connector between the I/O pack and the terminal board. The adjustment should only be required
once in the service life of the product.
Plug in one or two Ethernet cables depending on the system configuration. The I/O pack will operate over either port. If
4.
dual connections are used, the standard practice is to connect ENET1 to the network associated with the R controller.
5. Apply power to the pack by plugging in the connector on the side of the pack. It is not necessary to remove power from
the cable before plugging it in because the I/O pack has inherent soft-start capability that controls current inrush on
power application.
6. Connect ribbon cables from connector P2 on JPDG or JPDS to daisy chain other core boards feeding information to
PPDA.
Note Additional power distribution feedback signals may be brought into the PPDA I/O pack through the P2 connector on
the host board. The P1 connector is never used on a board that hosts the PPDA I/O pack, PPDA must always be at the end of
the feedback cable daisy chain.
7. Use the ToolboxST application to configure the I/O pack as necessary. From the Component Editor, press F1 for help.

In 240 V ac applications, do not inadvertently cross-connect the 240 V ac and the dc
voltages. The peak voltage will exceed the Transorb rating, resulting in a failure.
Most ac supplies operate with a grounded neutral, and if an inadvertent connection
between the 125 V dc and the ac voltage is created, the sum of the ac peak voltage and
the 125 V dc is applied to Transorbs connected between dc and ground. However, in
120 V ac applications, the Transorb rating can withstand the peak voltage without
causing a failure.
