Install the QDC Module
Chapter 2
2-6
To install your QDC module in an I/O chassis, complete the following:
1. First, turn off power to the I/O chassis.
ATTENTION: Remove power from the 1771 I/O chassis
backplane and wiring arm before removing or installing a QDC
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 module damage, degradation of performance, or
injury.
2. Place the module in the plastic guides on the top and bottom of the
slot that slides the module into position.
Important: Be aware that Pro-Set 600 software expects your Clamp and
Eject QDC module to be placed in slot 1 of your I/O rack. If you choose to
install your QDC module in some other slot, some modifications to your
PLC application program may be necessary (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.
