Installing the Module

Installation Precautions

Power is supplied to the module by the bus at the bottom of the rack (3.3 Vdc and 24 Vdc).

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH

Ensure that the turbomachinery is stopped while connecting or disconnecting the module or the terminal block.
Connect or disconnect the terminal block with sensor and pre-actuator voltage switched off.

Failure to follow these instructions will result in death or serious injury.

Backplane Slot Selection

In the main local rack, slot 00 (the first module slot after the power supply) is where the CPU is installed. In the main rack of a remote drop, slot 00 is where the (e)X80 EIO adapter module is installed. The remaining slots can be used by the module.

Before installing a module, take off the protective cap from the module connector located on the rack.

Installing the Module on the Rack

Mount the module in a single slot on the backplane:

Step	Action	Illustration
1	NOTE: Before positioning the pins, remove the protective cover. Position the locating pins situated at the rear of the module (on the bottom part) in the corresponding slots in the rack.
2	Swivel the module towards the top of the rack so that the module sits flush with the back of the rack. It is now set in position.
3	Tighten the retaining screw to hold the module in place on the rack. Tightening torque: 0.4...1.5 N•m (0.30...1.10 lbf-ft).
