Basic Safety Precautions
Every effort has been made to ensure that this unit will run with a minimum of user
input or maintenance. However, there are still precautions to be taken whenever
operating, performing maintenance, or servicing this unit. This unit makes use of
heating elements and electrical components, both of which pose inherent burn, fire,
and electrical shock hazards. These hazards can result in injury to personnel, the
plant, and/or the process. Please note the following to aid in the operation of your
unit and to decrease the risk of the above-mentioned hazards.
Precautions:
Carefully and completely read through this and all accompanying literature
completely to verify that you understand the functionality and features of this
system. Please become familiar with the integral safeties and controls within this
system, and know their functions.
Always disconnect all electrical power prior to installing, servicing, or replacing
electric heating elements and/or assemblies. The means for disconnection must
be incorporated in the fixed wiring in accordance with the wiring rule.
Electrical termination enclosures should be selected to match the application’s
environment and be able to withstand worst-case failures, especially in hazardous
locations.
Avoid fire hazards. Electric heaters and their components can develop
temperatures that produce an auto-ignition source. Avoid mounting heaters in
atmospheres containing combustible gases, vapor, or dust. Article 501 of the
National Electrical Code (NEC) requires that the maximum sheath temperature
when the heater is continually energized not exceed 80 percent of the surrounding
atmosphere’s auto-ignition temperature.
Avoid having heaters come in contact with combustible materials. Keep heaters
far enough away from combustible materials to prevent ignition.
Be aware of the labeling on the unit, such as a lightning-bolt warning symbol, which
alerts you to a safety hazard that could harm you or the unit.
While servicing or operating this unit it is advisable to remove all metal from the
individual working on the unit. This includes metal bracelets, rings and jewelry, as
well as metal rim glasses and wristwatches.
Keep your clothing, hands, and feet dry at all times whenever working with
electrical equipment.
Pull the fuses, open the circuit breakers, or disconnect the circuits from their source
of power to protect yourself, the test equipment and the equipment under test.
Do not troubleshoot or service a circuit with the primary power applied.
