2. Installation
The module must be used together with the AC Digital Input FTA T8824.
2.1. Module Insertion/Removal
CAUTION:
The module contains static sensitive parts. Static handling precautions must be observed.
Specifically ensure that exposed connector pins ARE NOT TOUCHED. Under no circumstances
should the module housing BE REMOVED.
Before installation, visually inspect the module for damage. Ensure that the module housing appears
undamaged and inspect the I/O connector at the back of the module for bent pins. If the module
appears damaged or any pins are bent, do not install the module. Do not try to straighten bent pins.
Return the module for replacement.
Ensure that the module is of the correct type.
Record the module type, revision and serial number of the module before installation.
To install the module:
1. Ensure that the field cable assembly is installed and correctly located.
2. Release the ejector tabs on the module using the release key. Ensure that the ejector tabs
are fully open.
3. Holding the ejectors, carefully insert the module into the intended slot.
4. Push the module fully home by pressing on the top and bottom of the module fascia.
5. Close the module ejectors, ensuring that they click into their locked position.
The module should mount into the chassis with a minimum of resistance. If the module does not
mount easily, do not force it. Remove the module and check it for bent or damaged pins. If the pins
have not been damaged, try reinstalling the module.
2.2. Field Cable Selection
The chassis end of the T8424 field cables are fitted with a 96 way type ‘C’ connector housed in either
a single width hood (TC-523) if the system is configured as smartslot or double hood (TC-223) if the
system is configured as companion slot. The other end of the cable is fitted with one 7-way and five
10-way BLZF 3.5 series connectors enabling the cable to be terminated at a T8824 FTA.
The field cables suitable for use with the Trusted
TM
TMR 120VAC Digital Input are detailed in the PD-
TC500 and TC200 product descriptions document. Refer to types TC-523 or TC-223.
