Failure to remove power from the backplane or wiring arm
could cause module damage, degradation of performance, or
injury.
2. Place the module in the plastic tracks on the top and bottom of the
slot that guides the module into position.
Important: Be aware that Pro-Set 600 expects your QDC module to be
placed in slot 0 of I/O rack 0 when operating in inject mode. If you choose
to install your QDC module in some other slot, some modifications to your
PLC-5 application program will be necessary (refer to your Pro-Set 600
documentation for details).
3. Do not force the module into its backplane connector. Apply a firm
and even pressure on the module to seat it properly.
4. Snap the chassis latch over the top of the module to secure it.
5. Connect the wiring arm to the module.
Use the wiring arm (1771-WF) supplied with the QDC module to wire I/O
devices (Figure 2.3). The wiring arm lets you install or remove the QDC
module from the I/O chassis without rewiring. Wiring arm terminals are
numbered in descending order from the top down, starting with terminal 18
(Figure 2.3 and Table 2.B).
