Install the QDC Module
Chapter 2
2-6
To install your QDC module in an I/O chassis, complete the following:
1. Turn off power to the I/O chassis.
ATTENTION: Remove power from the 1771 I/O chassis back-
plane and wiring arm before removing or installing a module.
Failure to remove power from the backplane could cause injury
or equipment damage due to possible unexpected operation.
Failure to remove power from the backplane or wiring arm
could cause injury, module damage, and/or degradation of
module performance.
2. Place the module in the plastic guides on the top and bottom of the
slot that slides the module into position.
Important: Pro-Set 600 software expects your QDC module (configured
for inject, clamp, and eject mode) to be placed in rack 0, module group 0,
slot 0. If you choose to install it in some other slot, you must modify your
PLC-5 application program accordingly (refer to your Pro-Set 600
documentation for details).
3. Do not force the module into its backplane connector. Apply firm,
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.
