Installing A Module - GE 90-30 PLC Series Installation And Hardware Manual

Installing a Module

Use the following instructions as a guide when inserting a module into a baseplate slot.
Figure 2-2. Installing a Module
GFK-0356Q Chapter 2 Installation
Do not insert or remove modules with power applied. This could cause the
PLC to stop or malfunction. Injury to personnel and damage to the module
or baseplate may result. Also, attempts to force a module into an improper
slot type will result in damage to the module and/or the baseplate. Modules
will mount in the correct slot type easily, with a minimum of force.
Check that module catalog number matches slot configuration. Each slot is, or will be,
assigned a particular module type during configuration. A Power Supply module must be
installed in the left end unnumbered slot only, and a CPU module and some special Option
modules can only be installed in Slot 1 of a CPU baseplate. I/O Modules and most Option
modules install in slots numbered 2 and higher.
Grasp the module firmly with terminal board toward you and with rear pivot hook facing
away from you.
Align the module with the desired baseplate slot and connector. Tilt the module upwards so
that top rear pivot hook of the module engages the baseplate's top module retainer.
Swing the module downward until the module's connector engages the baseplate's backplane
connector, and the release lever on the bottom of the module snaps into place in the
baseplate's bottom module retainer.
Visually inspect the module to be sure that it properly seated.
