SAFETY INFORMATION OVERVIEW
We use note, caution and warning symbols throughout this
book to draw your attention to important operational and
safety information.
“WARNING” describes an alert with information that is
important for protecting personnel and equipment from
damage.
“CAUTION” describes any condition that could result in
damage to the equipment or result in physical harm to
personnel.
The CAUTION or WARNING “SAFETY” alert symbol (an
exclamation mark in a triangle) precedes a general
caution or warning statement. It describes safety
requirements to meet local, national and
international standards.
The Electrical Shock Hazard CAUTION OR WARNING
symbol, (a lightning bolt in a triangle) precedes an
electric shock hazard. It describes a potential
electrical shock hazard which can result in personal
injury or death.
“NOTE” describes any item of interest to the user, owner, or
operator.
WARNINGS
Disconnect all power to circuits and panels where
this product is about to be installed or when
installing this product.
Follow extreme caution when applying NOsparc to trip
and close contacts or in circuits containing elements
that can be energized by a 1/2 power cycle pulse.
This User Manual must be thoroughly understood and
accurately followed to avoid unintended equipment operation.
The assembly must conform to National Electric
Code (NEC) safety standards, as well as locally
applicable codes. Failure to do so could result in
personal injury or loss of life. See the product rating
curve for wire gauge selection, ambient
temperature and current restrictions.
Follow extreme caution when conducting short
cycle time tests, especially below the maximum
rated cycle time for the associated relay; and
NEVER LESS THAN A 16s CYCLE TIME. Even at significantly
reduced power levels the relay contacts become extremely
hot due to high current densities at the point of contact
constriction just before the contact breaks open. Always
follow the relay manufacturers specifications and requirements
and DO NOT CYCLE CONTACTS MORE THAN 225 TIMES PER
HOUR.
Only authorized and qualified personnel should
install and service the NOsparc MGXDC1F250.
Failure to comply with these recommendations
may result in damage to equipment and property
and injury to personnel.
Always test the function and performance of NOsparc in the
intended application.
An arc suppressor DOES NOT eliminate arcing,
therefore, NOsparc will not eliminate hazards
associated with electrical current contact arcing.
SAFETY
All creepage distances and clearances of NOsparc have been
designed to meet requirements of safety standards.
When using NOsparc MGXDC1F250, basic safety precautions
should always be followed to reduce risk of fire, electric shock,
and injury to persons. When installing NOsparc into your
system, make sure that the Quick Connect Terminal
connector is properly crimped, terminated, insulated and that
the proper wire gauge is used and that the connector is
securely seated. Incorrect application or termination can
result in harmful or fatal electrical shock or component damage.
CAUTIONS
The NOsparc will pass a leakage current (see specifications)
even though the contacts across which it is connected are
open (similar to leakage present with snubber use). This
capacitive leakage current can be sufficient to turn-on some
solid state and electromechanical relays, or to cause electric
shock to personnel. Therefore:
–
The NOsparc must never be connected across relay, contactor, or
snap action switch contacts driving high impedance loads.
