SECTION 7: MAINTENANCE
7.1 INTRODUCTION
HIGH VOLTAGES ARE PRESENT IN AND AROUND
TRANSFER SWITCH EQUIPMENT. BEFORE
INSPECTING OR MAINTAINING THIS EQUIPMENT,
DISCONNECT LINE POWER FROM THE EQUIPMENT
BEING SERVICED BY OPENING AND LOCKING
OUT, IF POSSIBLE, THE NEXT HIGHEST DISCON-
NECT DEVICE. FAILURE TO FOLLOW THIS PROCE-
DURE COULD CAUSE PERSONAL INJURY AND/OR
DEATH.
THIS CLOSED TRANSITION PRODUCT CONTAINS A
SPECIAL CONTACT ARRANGEMENT (OVERLAP-
PING CONTACTS). MISUSE CAN RESULT IN DEATH,
SEVERE PERSONAL INJURY AND/OR PROPERTY
DAMAGE.
In general, transfer switch equipment is designed to be
relatively maintenance free under normal usage. How-
ever, because of the variability of application conditions
and the importance placed on dependable operation by
this type of equipment, inspection and maintenance
checks should be made on a regularly scheduled basis.
Since equipment maintenance will consist mainly of
keeping the equipment clean, the frequency of mainte-
nance will depend, to a large extent, on the cleanliness
of the surroundings. If a significant amount of dust or
foreign 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 regularly
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.
7.2 PROCEDURES
A suggested maintenance procedure to follow is out-
lined in Table 7.1.
