Maintenance and Safety
This chapter provides preventive maintenance information and safety
considerations when troubleshooting your SLC 500 system.
Preventive Maintenance 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.
The National Fire Protection Association (NFPA) recommends
maintenance procedures for electrical equipment. Refer to article 70B
of the NFPA for general requirements regarding safety related work
practices.
ATTENTION
To ensure personal safety and to guard against damaging
equipment, inspect connections with incoming power turned
OFF.
