Section 1: Safety Instructions
Before working with the Safety Bus system, carefully read this manual. All the installation and
maintenance operations described herewith must be carried out by qualified personnel. The Safety
Bus system must be used exclusively for the purposes it has been designed for and must operate
according to the operating conditions stated by the manufacturer. Furthermore, the field devices
connected to the system must be compatible and approved to operate with SB modules. Incorrect
use of this type of equipment, failure to observe the instructions provided in this manual or the
action of unqualified personnel can cause serious damage to people, premises and the surroundings
for which Honeywell shall not be responsible.
1.1 Protection Against Electrostatic Discharges
All Safety Bus system modules contain electronic components sensitive to electrostatic discharges.
Adopt the appropriate measures for preventing damage caused by electrostatic discharges. Trans-
port and keep all system components in containers with electrostatic discharge protection. Do not
remove components from their protective packaging until the moment of installation. Use a
grounded anti-static wrist strap to remove electrostatic discharges from the body during installa-
tion. Avoid contact with module terminal blocks.
1.2 Grounding
All Safety Bus system modules are equipped with a grounding screw located on the front panel and
identified by the relevant symbol. Ensure that all the modules are properly connected to the ground-
ing system using the appropriate conductor.
1.3 Equipment Modifications
All components, circuits and configuration parameters subject to hardware/software modifications
must be 100% tested.
