SECTION 8: MAINTENANCE
8.1 INTRODUCTION
HIGH VOLTAGES ARE PRESENT IN AND AROUND
TRANSFER SWITCH EQUIPMENT. BEFORE
INSPECTING OR MAINTAINING THIS EQUIPMENT,
DISCONNECT LINE POWER FROM LOCKING OUT,
IF POSSIBLE, THE NEXT HIGHEST DISCONNECT
DEVICE. FAILURE TO FOLLOW THIS PROCEDURE
COULD CAUSE PERSONAL INJURY AND/OR
DEATH.
In general, transfer switch equipment is designed to be
relatively maintenance free under normal usage.
However, because of the variability of application condi-
tions and the importance placed on dependable opera-
tion by this type of equipment, inspection and mainte-
nance checks should be made on a regularly scheduled
basis. Since equipment maintenance will consist mainly
of keeping the equipment clean, the frequency of main-
tenance will depend to a large extent on the cleanliness
of the surrounding. If a significant amount of dust of for-
eign matter is present, a more frequent maintenance
schedule should be followed.
It is suggested that visual inspections of the equipment
be made on a regular basis, not just during scheduled
periods. Always be alert for an accumulation of dirt in
and around the structure; loose parts and/or hardware;
cracks and/or discoloration to insulation; and damaged
or discolored components.
Figure 8-1 is the wiring diagram for the AGswitch auto-
matic transfer switch. Only qualified and experienced
personnel should attempt any diagnostic work using this
diagram.
8.2 PROCEDURES
A suggested maintenance procedure to follow is out-
lined in Table 8.1.
