PRE-ENERGIZATION CHECK
Page 35
Before closing the enclosure, all metal
chips, scrap wire and other debris left
over from installation must be cleaned
out.
If there is an appreciable accumulation
of dust or dirt, the enclosure should be
cleaned by using a brush, vacuum
cleaner or clean, lint free brush.
The integrity of all bus bar supports
must be checked for secureness and
damage.
Care should be exercised that when
covers are installed and doors closed,
no wires are pinched and that all
enclosure parts are properly aligned and
tightened.
A supply of spare parts, fuses, etc.
should be established.
Instruction manuals and diagrams
should be collected and filed.
WIRING CHECK (Fig. 41)
Field wiring should be checked for
clearance to
live
busses where
necessary, physically secured to
withstand the effects of fault current.
All grounding connections should be
checked.
Each motor should be connected to its
intended controller, and phase rotation
should be correct prior to startup.
Shorting jumpers (Fig. 42) for current
transformer secondary windings must
be removed once the secondary circuit
is completed. A circuit transformer
must not be operated with its
secondary windings open.
Changes made to circuit diagrams
during installation should be recorded.
