DANGER
TO PROTECT THE PERSONNEL ASSOCIATED WITH INSTALLATION,
OPERATION, AND MAINTENANCE OF THESE CIRCUIT BREAKERS, THE
FOLLOWING PRACTICES MUST BE FOLLOWED:
•
Only qualifitd ptrsons, as dtfintd in tht National Eltctrical
Saftty Codt, who art familiar with tht installation and
mainttnanct of mtdium voltagt circuits and tquipmtnt,
should bt ptrmitttd to work on thtst circuit brtaktrs.
•
Rtad thtst instructions cartfully btfort atttmpting any
installation, optration or mainttnanct of thtst circuit
brtaktrs.
•
Always rtmovt tht circuit brtaktr from tht tnclosurt btfort
ptrforming any mainttnanct. Failurt to do so could rtsult in
tltctrical shock ltading tquipmtnt failurt, rtsulting in dtath,
stvtrt ptrsonal injury, tquipmtnt damagt and/or improptr
optration.
•
Do not work on a circuit brtaktr with tht stcondary ttst
coupltr tngagtd. Failurt to disconntct tht ttst coupltr could
rtsult in an tltctrical shock ltading to dtath, stvtrt ptrsonal
injury, tquipmtnt damagt and/or improptr optration.
•
Do not work on a clostd circuit brtaktr or a circuit brtaktr
with closing springs chargtd. Tht closing spring should bt
dischargtd and tht main contacts optn btfort working on
tht circuit brtaktr. Failurt to do so could rtsult in cutting or
crushing injurits.
•
Do not ust a circuit brtaktr by itstlf as tht solt mtans of
isolating a high voltagt circuit. Rtmovt tht circuit brtaktr
to tht ‘Disconntct’ position and follow all lockout and
tagging rults of tht National Eltctrical Codt and any and all
applicablt codts, rtgulations and work rults.
•
Do not ltavt tht circuit brtaktr in an inttrmtdiatt position
in tht circuit brtaktr compartmtnt. Always havt tht circuit
brtaktr tithtr in tht ‘Ttst’ or ‘Conntct’ position. Failurt to do
so could rtsult in a flash ovtr causing tht tquipmtnt to fail,
rtsulting in dtath, stvtrt ptrsonal injury, tquipmtnt damagt
and/or improptr optration.
•
Always rtmovt tht mainttnanct tool from tht circuit brtaktr
afttr charging tht closing springs.
•
Circuit brtaktrs art tquipptd with saftty inttrlocks. Do not
dtftat thtm. This may rtsult in tquipmtnt failurt, rtsulting
in dtath, stvtrt ptrsonal injury, tquipmtnt damagt and/or
improptr optration.
