Maintenance and Safety
Preventative Maintenance This chapter provides preventive maintenance information and safety
considerations when troubleshooting your SLC 500 system.
The printed circuit boards of the analog modules must be protected
from dirt, oil, moisture and other airborne contaminants. To protect
these boards, the SLC 500 system must be installed in an enclosure
suitable for the environment. The interior of the enclosure should be
kept clean and the enclosure door should be kept closed whenever
possible.
Regularly inspect your terminal connections for tightness. Loose
connections may cause improper functioning of the SLC 500 system or
damage the components of the system.
For general maintenance procedures for electrical equipment, refer to
the requirements specific to your region.
•
Europe: Refer to the standards found in EN 60204 and your
national regulations.
•
United States: Refer to article 70B of the National Fire Protection
Association (NFPA). It describes general requirements regarding
safety related work practices.
Safety considerations are an important element of proper
troubleshooting procedures. Actively thinking about the safety of
yourself and others, as well as the condition of your equipment, is of
primary importance. Refer to the SLC 500 Fixed Hardware Style
Installation & Operation Manual (publication 1747-6.21) or the SLC
500 Modular Hardware Style User Manual (publication 1747-UM011)
for additional information on troubleshooting.
ATTENTION
To ensure personal safety and to guard against
equipment damage, inspect connections with
incoming power OFF.
