Safety-Related Slice Description

Overview

The following figure shows the three components of a safety-related slice:

1 Safety-related bus base

2 Safety-related electronic module

3 Safety-related terminal block

 DANGER
INCOMPATIBLE COMPONENTS CAUSE ELECTRIC SHOCK OR ARC FLASH
  • Do not associate components of a slice that have different colors.
  • Always confirm the compatibility of slice components and modules before installation using the association table in this manual.
  • Verify that correct terminal blocks (minimally, matching colors and correct number of terminals) are installed on the appropriate electronic modules.
Failure to follow these instructions will result in death or serious injury.

The safety-related bus base and the safety-related terminal block for the safety-related electronic module, must be ordered separately. For the references see respective sections below.

When assembled the three components form an integral unit that resists vibration and electrostatic discharge.

NOTICE
ELECTROSTATIC DISCHARGE
  • Never touch the contacts of the electronic module.
  • Always keep the connector in place during normal operation.
Failure to follow these instructions can result in equipment damage.

The compatibility table gives the possible associations between components of a slice.
