• WARNING
TO PROTECT PERSONNEL ASSOCIATED WITH INSTALLATION,
COMMISSIONING, OPERATION, AND MAINTENANCE OF THESE
SWITCHGEAR ELEMENTS, THE FOLLOWING PRACTICES MUST BE
FOLLOWED:
Only qualified persons, as defined in the local electrical code, who
•
are familiar with the installation and maintenance of medium-voltage
circuits and equipment, should be permitted to work on switchgear.
Read these instructions carefully before attempting installation or
•
commissioning of this equipment.
Do not work on a closed breaker mechanism or a breaker mechanism
•
with closing springs charged. The closing spring should be discharged
and the main contacts opened before working on the breaker
mechanism. Failure to do so could result in injuries.
Do not use a circuit breaker by itself as the sole means of isolating a
•
high voltage circuit. Open or ground the associated 3PS for verification
of the isolating gap and follow necessary lockout tagout procedures, as
well as all applicable codes, regulations and work rules.
Power Xpert IGX switchgear employs pressurized insulating gas in the
•
enclosure tanks. Special precautions must be followed if service is
required on the insulating gas tanks.
The insulating gas is heavier than air and will displace air in a confined
•
space. This can present a suffocation hazard.
Never allow only one person to access any Power Xpert IGX tank to
•
perform maintenance or service work.
Once Power Xpert IGX tank service is completed, personnel must clean
•
their hands, faces and exposed skin immediately. Tools and PPE must
also be cleaned.
The insulating gas MUST NOT be discharged into the atmosphere. It
•
should be collected and may be reused only after treatment and testing
by qualified experts.
