How to mount processor modules

Introduction

NOTICE

PLC MODULE DESTRUCTION

Switch off the rack power supply before mounting a processor module.

Failure to follow these instructions can result in equipment damage.

NOTE: Mounting and removing processor modules is otherwise identical to mounting and removing other modules.

when extracting/inserting modules with the power on, the terminal block or HE10 connector must be disconnected. You must also take care to shut off the sensor/pre-actuator supply.

Installing a processor module onto a rack

Carry out the following steps:

Step	Action	Illustration
1	Place the pins at the back of the module into the centering holes on the lower part of the rack (number 1, see diagram 1).
2	Swivel the module to bring it into contact with the rack (number 2).
3	Fix the processor module to the rack by tightening the screw on the upper part of the module (number 3).

NOTE: the mounting of processor modules is identical to the mounting of other modules.

NOTE: Maximum tightening torque: 2.0 Nm (1.5 lb. ft.)

Grounding modules

Processor modules are grounded using metal plates at the rear of the module. When the module is in place, these metal plates are in contact with the metal of the rack. This ensures the link with the ground connection.
