NOTE:
To open a dipswitch, press down on the side of
the dipswitch marked OPEN. To close a

slide switch, push the slide to the side marked ON.
Do NOT install the card in its edge connector
until ALL OMM-1 field wiring is completed and
checked for shorts, opens, and other faults.
Refer to the Wiring Checkout Chart. Replace
the card in its protective bag if the wiring is not
complete.
Find the card slot key provided in the installation
kit with the ZCT-8B board. Place the card slot key
in the OMM-1 edge connector for the ZCT-8B as
shown in Figure 2. See Figure 3 for the exact

location of the key for this module. This prevents
installation of any other card type in the ZCT-8B
slot. Two other keys already installed in the
OMM-1 prevent reverse installation of the card in
the OMM-1 edge connectors. (See Figure 3.)
Place the card in its card edge connector cor-
rectly. The components on the board must face
the 22 position terminal block where the wiring is
terminated. Press the card firmly in place to be
sure it is seated properly in the edge connector.
